The major components of the BCI are two copies of the SRI Core Language Engine, equipped with English and Swedish grammars respectively. These are linked by the transfer and disambiguation components. Translation takes place by analyzing the source-language sentence into Quasi Logical Form (QLF), a linguistically motivated logical representation, transferring this into a target-language QLF, and generating a targetlanguage sentence. When ambiguities occur that cannot be resolved automatically, they are clarified by querying the appropriate user. The clarification dialogue presupposes no knowledge of either linguistics or the other language. The prototype system has a broad grammatical coverage, a initial vocabulary of about 1000 words together with vocabulary expansion tools, and a set of English-Swedish transfer rules. The formalisms developed for coding this linguistic information make it relatively easy to extend the system. We believe that the project was successful in demonstrating the feasibility of using these techniques for interactive translation applications, and provides a sound basis for development of a large scale message translator system with potential for commercial exploitation.}, Year = {1991} } @techreport{ Alshawi:1991:TTQ, Author = {Alshawi, Hiyan and Carter, David M. and Gambäck, Björn and Pulman, Stephen G. and Rayner, Manny}, Title = {Transfer through Quasi Logical Form: A New Approach to Machine Translation}, Address = {Stockholm, Sweden}, Institution = {SICS}, Number = {T91020}, Type = {Technical Report}, CoLiURL = {Alshawi:1991:TTQ.pdf Alshawi:1991:TTQ.ps}, URL = {www.sics.se/humle/papers/T91020.ps}, Abstract = {This document is an introduction to a research project aimed at produc- ing a prototype system for on-line translation of typed dialogues between speakers of different natural languages.

By shifting the peak leftwards towards the beginning of the accented syllable (H*) the pragmatic category changed from check to statement. Both categories have a L% boundary tone. However, subjects' judgements indicated that the strength of the intonational information was not equal for the two utterance types. The situational pre-context had a strong influence on the interpretation of the utterance as a check or statement. In case the intonation contour diverged from the unmarked contour for a particular function, the category judgement was accompanied by a change in the emotional message. To examine the general validity of these observations a further experiment was carried out. Three checks, three statements with low terminal boundary tones (L%), and three statements with continuation rises (H%) were selected from Map Task recordings made for a number of male and female speakers [3]. From each of these 9 natural utterances three intonational variants were generated, one for each pragmatic category. Firstly, a stylised resynthesized version of the original (e.g. a check) was produced. Then the intonation contours for the other two pragmatic categories (e.g. statement with terminal fall and continuation rise) were derived from the stylised contour. Four repetitions of the stimuli were presented (Roman square design) to 15 native speakers of Sofia Bulgarian in three situational contexts: question, neutral statement and polite statement. The context utterance together with the stimulus form a minimal dialogue. The natural context for the check was a statement, and for the two statement forms it was a question. In the test, each context was offered with each pragmatic category, producing potential tension between context and stimulus. The subjects were required to judge - on a five-point scale - the degree to which each stimulus was suited to its context. The results show that all three intonational contours can be accepted as statements in the context of a preceding question, whereas the change of context cannot shift the interpretation of a statement to a check. The following explanation can be offered for this asymmetry of reinterpretation. The context plays an extremely important role for the interpretation of checks or statements. The context priming a statement (question-answer sequence) provides enough information to uniquely specify the communicative frame. It is a strong enough speech act marker to relegate function of the intonational form to a minor one. Thus the context weakens the distinctive function that intonation has when word sequence and syntactic structure are identical.This does not, however, mean that the intonational form is irrelevant. The shift in the interpretation of the sentence mode (check to statement) can only occur because a compensatory change of modal meaning accompanies it. The check contour cannot be accepted as a neutral statement, it can only be accepted as an emphatic, impatient or angry statement. The statements with a continuation rise were also accepted in the statement context, but the compensatory modal message was of an exaggeratedly polite speaker. Apparently, when a typical (neutral) feature of a particular communicative situation is replaced by a feature typical of another situation, it introduces an additional modal marking. Thus intonation alone, without syntactic and lexical support, can imply a certain shade of modal meaning. This phenomenon is already known at the grammatical level. In Bulgarian, for example, the future tense is the neutral form for referring to events in the future. If the present tense is used, the utterance is immediately modally marked as a firm intention. In English and German the reverse is true.}, Year = {2000} } @inproceedings{ Andreeva:1999:RBT, Author = {Andreeva, Bistra and Koreman, Jacques and Barry, William J.}, Title = {On the Role of the Burst and Transitions for the Identification of Palatalized and Non-Palatalized Plosives in Bulgarian}, BookTitle = {Proceedings of the 14th International Congress of Phonetic Sciences (ICPhS'99), August 1-7}, Address= {San Francisco, USA}, CoLiURL = {Andreeva:1999:RBT.pdf Andreeva:1999:RBT.ps}, URL = {http://www.coli.uni-sb.de/~koreman/Publications/1999/ICPhS99_BulgPal.ps.gz}, Year = {1999} } @techreport{ Areces:1999:HLC, Author = {Areces, Carlos and Blackburn, Patrick and Marx, Maarten}, Title = {Hybrid Logics: Characterization, Interpolation and Complexity}, Address = {Saarbrücken}, Institution = {Universität des Saarlandes}, Number = {108}, Type = {CLAUS-Report}, Month= {February}, Pages = {35}, CoLiURL = {Areces:1999:HLC.pdf Areces:1999:HLC.ps Areces:1999:HLC.dvi}, URL = {ftp://ftp.coli.uni-sb.de/pub/coli/claus/claus108.ps ftp://ftp.coli.uni-sb.de/pub/coli/claus/claus108.dvi}, Abstract = {Hybrid languages are extended modal languages which can refer to (or even quantify over) worlds.

The key result to emerge is that the system corresponds precisely to the first-order fragment which is invariant for generated submodels.

Almost no such attempts have been made before, although some of the syntactic problems that arise have been mentioned and treated from different viewpoints in studies concerned with complex tenses, with voice and mood, with the status of pronouns, of negative and interrogative particles etc. The partially free word order of Bulgarian has been mentioned in very few works based on the transformational approach. For the sake of description of the Bulgarian verb complex, we felt we had to refrain from some of the standards of the linguistic background of many current non-transformational (as well as other) approaches. The changes we introduced concern the constituent structures used and they consist inriching the established approach with ideas stemming from the works of the Prague Linguistic School, namely with the notion of communicative dynamism. The shape of the structures is briefly sketched in the first part of the work, while the linguistic facts and their description are the main content of its second part; in the closing paragraphs, some phenomena are mentioned which were not examined in detail in the central sections of the work and their incorporation into the description as presented before is considered.}, Year = {1991} } @article{ Avgustinova:1995:WPR, Author = {Avgustinova, Tania and Oliva, Karel}, Title = {Wackernagel Position and Related Phenomena in Czech}, Journal = {Wiener Slavistisches Jahrbuch}, Volume = {41}, Pages = {21-42}, Year = {1995} } @techreport{ Avgustinova:1995:PSC, Author = {Avgustinova, Tania and Oliva, Karel}, Title = {The Position of Sentential Clitics in the Czech Clause}, Address = {Saarbrücken}, Institution = {Universität des Saarlandes}, Number = {68}, Type = {CLAUS-Report}, Month= {December}, Abstract = {Our main goal is to propose a unified analysis of the "second position" and Wackernagel phenomena, which would adequately accommodate also certain non-trivial data that seem to be problematic for the currently available approaches: 1. Correct sentences with multiple syntactic constituents preceding the sentential clitics in Czech, and respectively, multiple syntactic constituency in the German "Vorfeld": a. Czech clitics (respectively, the tensed verb in German main clauses) preceded by two or more adverbials describing together a spatial or temporal interval; b. Czech clitics (respectively, the tensed verb in German main clauses) preceded by two or more adverbials of the same type, which can be viewed as a repetition of the respective modification; c. Czech clitics (respectively, the tensed verb in German main clauses) preceded by a combination of a temporal and a local adverbial; d. Czech clitics (respectively, the tensed verb in German main clauses) preceded by more than one contrasted syntactic constituents 2. Sentences with a single constituent preceding the sentential clitics (respectively, single constituent in the "Vorfeld") but judged to be highly unacceptable . We reconsider the Prague School treatment of the communicative structure of the sentence, and assume that, for each particular utterance, it can be determined which of the contained elements are informationally essential (significant) - i.e. informationally indispensable from a communicative perspective - and which of them are informationally unessential (insignificant) - i.e. without actual communicative contribution - and occur in the utterance for other, e.g., structural, pleonastic etc., reasons only. On such a basis we (re)introduce the notion of communicative importance. We further assume that not all elements of an utterance can be assigned a degree of communicative dynamism - i.e. that there are items for which the feature communicative importance is inappropriate. Another assumption is that in an utterance there might exist two or more syntactically distinguishable constituents which are of equal communicative importance. After these modifications, we introduce a structuring of an utterance into communicative units which we tentatively call communicative segments. A substantial communicative segment is defined as a contiguous sequence of adjacent syntactic units (i.e. words or phrases) of equal communicative importance, while an auxiliary communicative segment is a contiguous sequence of informationally insignificant items for which communicative importance is inappropriate as a feature. From such a perspective the Wackernagel's clitic cluster in Czech is regarded as an instance of an auxiliary communicative segment. We further define the "second" / Wackernagel position as the position delimiting the first (leftmost) substantial communicative segment in an utterance, and thus propose an alternative treatment also of the German "Vorfeld". Inasmuch as there are language-specific constraints on what can form a substantial communicative segment, our analysis allows for a natural explanation also of, e.g., the "constituent-second" / "word-second" position of Serbo-Croatian clitics.}, Year = {1995} } @inproceedings{ Avgustinova:1996:CNW, Author = {Avgustinova, Tania and Oliva, Karel}, Title = {The Communicative Nature of the Wackernagel Position}, BookTitle = {Prague School Linguistics Conference}, Address= {Prague}, Year = {1996} } @techreport{ Avgustinova:1996:UDH, Author = {Avgustinova, Tania and Oliva, Karel}, Title = {Unbounded Dependencies in HPSG Without Traces or Lexical Rules}, Address = {Saarbrücken}, Institution = {Universität des Saarlandes}, Number = {70}, Type = {CLAUS-Report}, Month= {January}, Abstract = {In the course of work on large-coverage HPSG grammars destinated for application in commercial grammar checkers for Bulgarian and Czech, two languages typologically different from English with respect to the word order freedom, we have developed and practically tested an alternative, efficient-implementation oriented treatment of unbounded dependencies dispensing both with gaps and with lexical rules.

Während existierende Dialogsysteme zur Kommunikation zwischen der Maschine und einem einzigen menschlichen Benutzer gedacht sind, nimmt das DISCO-System an Dialogen zwischen mehr als zwei Teilnehmern teil. Die autonomen kooperierenden Agenten, für die das DISCO-System geschaffen wurde, sind KISoftwaresysteme auf vernetzten Computern. DlSCO führte Forschung sowohl in Computerlinguistik als auch in anderen Gebieten der KI durch. Frühere Arbeiten an natürlichsprachlichen Dialogsystemen konzentrierten sich entweder auf moderne Methoden für die linguistische Spezifikation und die Sprachverarbeitung oder auf fortgeschrittene Dialogverarbeitung. Im Unterschied dazu konnte DISCO erfolgreich Resultate aus beiden Gebieten integrieren.

TDL distinguishes between AVM types (open-world reasoning) and SORT types (closed-world reasoning) and allows the declaration of partitions and incompatible types. Working with partially as well as with fully expanded types is possible, both at definition and at run time.

Silbenanfang. Die Aussprache von Wörtern, die auf "-ig" enden wird durch ein "Archiphonem" /G/ geregelt. Für potentiell intervokalische /r/ am Ende des Wortstammes wird [6r] transkribiert. So können durch systeminterne Umwandlungsregeln sowohl intervokalische als auch präkonsonantische /r/ korrekt ausgesprochen werden. Bezüglich der Realisierung der Phonemfolge /@r/ wurde ein Bewertungsexperiment mit folgendem Ergebnis durchgeführt: [6] wurde in den meisten Kontexten besser bewertet als [@]. Insbesondere im Folgen von unbetonten Silben, wenn der Wortstamm auf /@r/ endet (unabhängig von Betontheit der Folgesilbe) und in den Vorsilben "ver-", "zer-" und "er-".

An "archiphoneme" /G/ controls the pronunciation of morphemes ending in "-ig". By transcribing [6r] system internal rules can be used to account for the different realisation of /r/ stem-finally in intervocalic and preconsonantal position. A perception experiment was carried out in order to evaluate the realisation of /@/ before /r/.

The main aim of theGerman government funded FLAGproject1 is to develop technologies for controlled language (CL) and grammar checking applications for German. The project work has therefore been divided into two separate but complementary streams of activity. Firstly, the aim was to develop an modular NLP software architecture for quickly developing different kinds of CL and grammar checking applications. Secondly, to validate the first activity, it was seen as important to build up an empirical base for testing and formally evaluating checking components. Given the lack of existing annotated corpora of errors for German (or indeed for any language as far as the authors know), the construction of such a corpus was a high priority task. This would enable us not only to perform quantitative tests, but also to derive an empirically based typology of errors which the project could use for orientation. The corpus was particularly important given the approach which the FLAG project was taking to the task of grammar and controlled language checking, which relies on a phenomenonoriented approach to the problem of identifying errors, using shallow processing techniques. In order to finetune the heuristics which are central to such an approach, i.e. one based on identifying “candidate errors” of increasing probability, it is essential to have good test suites annotated with respect to the phenomena under investigation. The annotation of the corpus was to be carried out in such a way that we could easily access and quantify snapshots of the data, for producing test suites for testing purposes and for producing statistics on the frequency of particular error types. The research community not only lacked an annotated corpus of errors, there was no existing ontology of errors which could be easily translated into an annotation schema. The definition of such a schema based on traditional descriptions of errors (such as Luik, 1993a; Luik, 1993b) thus formed the first major workpackage. Fortunately, tools for the annotation of corpora, and the management thereof are becoming increasingly sophisticated; it was therefore necessary to evaluate a number of tools in the light of our specific needs.}, Year = {1999} } @inproceedings{ Bretan:1996:MET, Author = {Bretan, Ivan and Engstedt, Maans and Gambäck, Björn}, Title = {A Multimodal Environment for Telecommunication Specifications}, BookTitle = {Recent Advances in Natural Language Processing (RANLP '96).

In general, information extraction (IE) is a rather scaled down version of natural language understanding, in which there is little room for the processing of deep (i.e. lexical semantic) knowledge. However, in obvious ways, underspecified lexical semantic representations can be seen as shallow lexical meanings that have a similar status as chunks in syntactic processing. Therefore, the use of such representations in IE seems an attractive option to extend the semantic capabilities of these systems, although it is not entirely clear where underspecification will be useful and where not.

Systematic polysemy -- senses that are systematically related and therefore predictable over classes of lexical items -- is fundamentally different from homonymy -- senses that are unrelated, non-systematic and therefore not predictable. At the same time, studies in discourse analysis show that lexical items are often left underspecified for a number of related senses. Clearly, there is a correspondence between these phenomena, the investigation of which is the topic of this paper. Acknowledging the systematic nature of polysemy and its relation to underspecified representations, allows one to structure ontologies for lexical semantic processing more efficiently, generating more appropriate interpretations within context. In order to achieve this, one needs a thorough analysis of systematic polysemy and underspecification on a large and useful scale. The paper establishes an ontology and semantic database (CoreLex) of 126 semantic types, covering around 40,000 nouns and defining a large number of systematic polysemous classes that are derived by a careful analysis of sense distributions in WordNet. The semantic types are underspecified representations based on generative lexicon theory.}, Year = {1998} } @inproceedings{ Buitelaar:1999:ASA, Author = {Buitelaar, Paul}, Title = {Ambiguity in Semantic Annotation Submitted}, BookTitle = {Standardizing Lexical Resources Workshop (SIGLEX '99), June 21-22}, Address= {University of Maryland College Park, USA}, Year = {1999} } @inproceedings{ Buitelaar:2000:RLS, Author = {Buitelaar, Paul}, Title = {Reducing Lexical Semantic Complexity with Systematic Polysemous Classes and Underspecification}, BookTitle = {Workshop on Syntactic and Semantic Complexity in Natural Language Processing Systems (ANLP-NAACL'00), April 29 - May 3}, Editor = {Bagga, Amit and Pustejovsky, James and Zadrozny, Wlodek}, Address= {Seattle, Washington, USA}, CoLiURL = {Buitelaar:2000:RLS.pdf Buitelaar:2000:RLS.ps}, URL = {ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/anlp00.ps. http://dfki.de/~paulb/anlp00.ps}, Abstract = {This paper presents an algorithm for finding systematic polysemous classes in WordNet and similar semantic databases, based on a definition in (Apresjan 1973).

A common practice in this respect is labeling of documents with thesaurus classes for the sake of document classification and management. In the medical domain, for instance, there is a long-standing tradition in terminology maintenance and annotation/classification of documents using standard coding systems such as ICD, MeSH and the UMLS meta-thesaurus. Semantic annotation in a broader sense also addresses document structure (title, section, paragraph, etc.), linguistic structure (dependency, coordination, thematic role, co-reference, etc.), and so forth. In NLP, semantic annotation has been used in connection with machine-learning software trainable on annotated corpora for parsing, word-sense disambiguation, co-reference resolution, summarization, information extraction, and other tasks. A still unexplored but important potential of semantic annotation is that it can provide a common I/O format through which to integrate various component technologies in NLP and AI such as speech recognition, parsing, generation, inference, and so on. INTELLIGENT CONTENT is semantically structured data that is used for a wide range of content-oriented applications such as classification, retrieval, extraction, translation, presentation, and question-answering, as the organization of such data provides machines with accurate semantic input to those technologies. Semantically annotated resources as described above are typical examples of intelligent content, whereas another major class includes electronic dictionaries and inter-lingual or knowledge-representation data. Some ongoing projects along these lines are GDA (Global Document Annotation), UNL (Universal Networking Language) and SHOE (Simple HTML Ontology Extension), all of which aim at motivating people to semantically organize electronic documents in machine-understandable formats, and at developing and spreading content-oriented application technologies aware of such formats. Along similar lines, MPEG-7 is a framework for semantically annotating audiovisual data for the sake of content-based retrieval and browsing, among others. Incorporation of linguistic annotation into MPEG-7 is in the agenda, because linguistic descriptions already constitute a main part of existing metadata. In short, semantic annotation is a central, basic technology for intelligent content, which in turn is a key notion in systematically coordinating various applications of semantic annotation. In the hope of fueling some of the developments mentioned above and thus promoting the linkage between basic researches and practical applications, the workshop invites researchers and practitioners from such fields as computational linguistics, document processing, terminology, information science, and multimedia content, among others, to discuss various aspects of semantic annotation and intelligent content in an interdisciplinary way.}, Year = {2000} } @inproceedings{ Buitelaar:1994:CCC, Author = {Buitelaar, Paul and Mineur, Anne-Marie}, Title = {Coercion and Compositionality in Categorial Grammar}, BookTitle = {9th Amsterdam Colloquium}, Editor = {Dekker, P. and Stokhof, M.}, Address= {Amsterdam}, Publisher = {Institute for Logic, Language and Computation}, Pages = {175-188}, CoLiURL = {Buitelaar:1994:CCC.pdf Buitelaar:1994:CCC.ps}, URL = {Full text in postscript gzipped http://dfki.de/~paulb/ac93.ps.gz}, Year = {1994} } @inproceedings{ Buitelaar:1998:IDS, Author = {Buitelaar, Paul and Netter, Klaus and Xu, Feiyu}, Title = {Integrating Different Strategies in Cross-Language Information Retrieval in the MIETTA Project}, BookTitle = {Proceedings of the 14th Twente Workshop on Language Technology (TWLT 14).

Whether lexical choice must be exact in the sense that all and only the intended meaning is verbalized, depends on the respective communication situation. In a multimodal discourse, where language is supplemented by gestures or graphics, the linguistic device need not convey everything to the partner. In written discourse without a predefined context, as in DISCO, exact verbalization seems much more in order. In all theories of lexical choice, the convergence problem has to be solved: there is always a decision for exactly one lexical item. We may distinguish the following subtasks of lexical choice: Definite reference, proforms: Events and objects must often be described using words that allow for an unambiguous identification of the referent. The problem subdivides in finding appropriate words for the referents and in describing the relations between them, as deictic and intrinsic readings of "The ball is infront of the car" suggest. Social jugdement: Some words carry social jugdements with them. German Putzfrau and Raumpflegerin mean both cleaning woman, but only the latter is now used officially.1 The former has a pejorative connotation. See [6]. Collocations: There are different kinds of cooccurrence restrictions between lexemes. Some words cannot be used together with others, some tend to be used together with others and some yield a different meaning when used with certain others (idioms). Choice of open class words: Given a conceptual representation of the intended meaning, an appropriate word for each concept must be identified. In this paper, we assume that for lexical selection the following kinds of knowledge are necessary: • the concepts of the meaning representation language • lexical entries (lemmata and/or phrasal items including semantic and syntactic in formation, among other things ) • knowledge about the reader (including the reader's goals ans beliefs) • knowledge about the linguistic, situational, and social context We will show that lexical choice requires a domain model based on linguistic considerations, and that standard KL-ONE techniques are insufficient for parts of the task at hand.}, Year = {1992} } @incollection{ Busemann:1993:HVL, Author = {Busemann, Stephan}, Title = {A Holistic View of Lexical Choice}, BookTitle = {New Concepts in Natural Language Generation: Planning, Realization and Systems}, Editor = {Horacek, H.}, Address = {London}, Publisher = {Frances Pinter}, Pages = {302-308}, CoLiURL = {Busemann:1993:HVL.pdf Busemann:1993:HVL.ps Busemann:1993:HVL.dvi}, URL = {ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/lex-choice.dvi.Z ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/lex-choice.entry ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/lex-choice.ps.Z}, Abstract = {Recently the problem of choosing communicatively adequate lexemes has attracted much interest in the NL generation community.

Surface generation starts from input semantics representations that may vary across grammars. For many declarative grammars, the concept of derivation implicitly built in is that of parsing. They may thus not be interpretable by a generation algorithm. We show that linguistically plausible semantic analyses can cause severe problems for semantic-head-driven approaches for generation (SHDG). We use SeReal, a variant of SHDG and the DISCO grammar of German as our source of examples. We propose a new, general approach that explicitly accounts for the interface between the grammar and the generation algorithm by adding a control-oriented layer to the linguistic knowledge base that reorganizes the semantics in a way suitable for generation.}, Year = {2000} } @inproceedings{ Busemann:2001:LGC, Author = {Busemann, Stephan}, Title = {Language Generation for Cross-Lingual Document Summarisation}, BookTitle = {Proceedings of the International Workshop on Innovative Language Technology and Chinese Information Processing (ILT&CIP '01)}, Editor = {Sheng, Hyanye}, Address= {Shanghai}, Publisher = {Science Press}, CoLiURL = {Busemann:2001:LGC.pdf}, URL = {ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/musi-nlg.entry ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/musi-nlg.pdf}, Year = {2001} } @inproceedings{ Busemann:2002:IGI, Author = {Busemann, Stephan}, Title = {Issues in Generating from Interlingua Representations}, BookTitle = {Proceedings of the 1st International Workshop on UNL, other Interlinguas and their Applications}, Editor = {Tovar, Edmundo and Gallardo, Carolina}, Address= {Las Palmas}, Pages = {1-7}, CoLiURL = {Busemann:2002:IGI.pdf}, URL = {ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/interlingua.entry ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/interlingua.pdf}, Abstract = {Multi-lingual generation starts from non-linguistic content representations for generating texts in different languages that are equivalent in meaning.

Im Jahr 2002 wird die nunmehr sechste KONVENS von der GI, Fachgruppe "Natürlichsprachliche Systeme'', in Saarbrücken veranstaltet. Themen der wissenschaftlichen Konferenz sind alle Bereiche der maschinellen Verarbeitung von natürlicher Sprache in gesprochener als auch in geschriebener Form. Die Tagung verfolgt das Ziel, einen breiten Querschnitt durch die aktuelle Forschung und Entwicklung im Gebiet der Sprachverarbeitung zu bieten - unter Einschluss aller relevanten Disziplinen wie Computerlinguistik, Sprachtechnologie, Kognitions-Psychologie, Informatik, Akustik und Nachrichtentechnik. Beiträge aus der gesamten Bandbreite zwischen Forschung, Entwicklung, Anwendung und Evaluation von natürlichsprachlichen Ressourcen, Komponenten und Systemen waren in Form unveröffentlichter Forschungs- und Entwicklungsergebnisse oder innovativer industrieller Anwendungen willkommen. 44 Papiere wurden eingereicht und von je zwei Mitgliedern des Programmkomitees begutachtet, die teilweise weitere Gutachter hinzuzogen. In diesem Begutachtungsverfahren wählte das Programmkomitee 22 Beiträge als Vorträge und 11 als Poster zur Präsentation während der Tagung und zur Veröffentlichung aus. Zudem konnten zwei hochrangige Wissenschaftler gewonnen werden, ihre aktuellen Arbeiten in Form eingeladener Vorträge vorzustellen. Christiane Fellbaum (Princeton University und Berlin-Brandenburgische Akadamie der Wissenschaften) beschreibt Arbeiten zur Repräsentation idiomatischer Wendungen im Lexikon und lexikalischen Datenbanken (WordNet). Matthew Crocker (Universität des Saarlandes) zieht Verbindungen zwischen Psycholinguistik und statistischer Computerlinguistik. Der vorliegende Tagungsband enthält Kurzfassungen der eingeladenen Vorträge sowie die angenommenen Vorträge und Poster. Im Namen des Programmkomitees danke ich herzlich allen Autorinnen und Autoren, die durch ihre Einreichung ein interessantes und anspruchsvolles Tagungsprogramm ermöglichten. Besonders möchte ich den beiden eingeladenen Vortragenden, Christiane Fellbaum und Matthew Crocker, für ihre Beiträge danken.

In order to improve this situation, we suggest and evaluate shallow generation methods associated with increased flexibility.

But especially the computer screen yields the possibility to present informations in the form of animated graphics, i.e. animations. [Badler'90, Karp'90]. One advantage of animations is, that the dimension Time (succession, duration) can immediately be expressed. Another advantage is, that in an animation it is much easier to (virtually) cross the border to the third spatial dimension than it is in statical graphics. The problem of synthesizing an animation was regarded in this work as a planning problem and the result is an animation planner that, starting from an visualization goal, plans the whole script for an animation including all low-level camera and object motions. The system takes all decisions about camera positions, zooms, moves and cuts considering the actual context as well as some fundamental filmmaking rules [Karp'90]. The script is then realized by a given animation system which computes the single frames and does the playback. BETTY is part of the multimodal user interface WIP (Knowledge-based Presentation of Information, [Wahlster'93]), that generates instructions for technical devices.

It is based on activation-evaluation space, a representation derived from psychology. The activation dimension measures how dynamic the emotional state is; the evaluation dimension is a global measure of the positive or negative feeling associated with the state. Research suggests that the space is naturally circular, i.e. states which are at the limit of emotional intensity define a circle, with alert neutrality at the centre. To turn those ideas into a recording tool, the space was represented by a circle on a computer screen, and observers described perceived emotional state by moving a pointer (in the form of a disc) to the appropriate point in the circle, using a mouse. Prototypes were tested, and in the light of results, refinements were made to ensure that outputs were as consistent and meaningful as possible. They include colour coding the pointer in a way that users readily associate with the relevant emotional state; presenting key emotion words as ‘landmarks’ at the strategic points in the space; and developing an induction procedure to introduce observers to the system. An experiment assessed the reliability of the developed system. Stimuli were 16 clips from TV programs, two showing relatively strong emotions in each quadrant of activationevaluation space, each paired with one of the same person in a relatively neural state. 24 raters took part. Differences between clips chosen to contrast were statistically robust. Results were plotted in activation-evaluation space as ellipses, each with its centre at the mean co-ordinates for the clip, and its width proportional to standard deviation across raters. The size of the ellipses meant that about 25 could be fitted into the space, i.e. FEELTRACE has resolving power comparable to an emotion vocabulary of 20 non-overlapping words, with the advantage of allowing intermediate ratings, and above all, the ability to track impressions continuously.}, Year = {2000} } @proceedings{ Cowie:2000:PIW, Editor = {Cowie, Roddy and Douglas-Cowie, Ellen and Schröder, Marc}, Title = {Proceedings of the ISCA Workshop on Speech and Emotion: A Conceptual Framework for Research}, Address= {Belfast}, Publisher = {Textflow}, URL = {http://www.qub.ac.uk/en/isca/proceedings}, Year = {2000} } @inproceedings{ Creary:1989:RL, Author = {Creary, Lewis G. and Gawron, Jean Mark and Nerbonne, John}, Title = {Reference to Locations}, BookTitle = {27th Annual Meeting of the Association for Computational Linguistics (ACL-ANNUAL '89), June 26-29}, Editor = {ACL}, Address= {Vancouver, British Columbia, Canada}, Pages = {42-50}, Year = {1989} } @incollection{ Crocker:1999:MSP, Author = {Crocker, Matthew}, Title = {Mechanisms for Sentence Processing}, BookTitle = {Language Processing}, Editor = {Garrod, S. and Pickering, M.}, Address = {London}, Publisher = {Psychology Press}, Year = {1999} } @inproceedings{ Crocker:1999:IPM, Author = {Crocker, Matthew and Brants, Thorsten}, Title = {Incremental Probabilistic Models of Human Linguistic Performance}, BookTitle = {5th Conference on Architectures and Mechanisms for Language Processing (AMLaP '99), September 23-26}, Address= {Edinburgh, Scotland}, Abstract = {Models of human language processing increasingly advocate probabilistic mechanisms for parsing and disambiguation (e.g. Jurafsky, 1996; MacDonald et al 1994; Crocker and Corley; to appear). These models resolve local syntactic and lexical ambiguity by promoting the analysis which has the greatest probability of being correct. In this talk we will outline a new probabilistic parsing model which is a generalisation of the Hidden Markov Models which have previously been defended as pschological models of lexical category disambiguation (Corley and Crocker, in press). The model uses layered, or cascaded, markov models (CMMs) to build up a syntactic analysis (Brants, 1999). In contrast with many probabilisic parsing models, CMMs can easily be implemented to parse incrementally. Incremental CMMs have the property of generating partial structures including hypothetical continuations after receiving each new word in the input. New material is incorporated into the existing structure and ambiguities are resolved based on local context. Alternative hypotheses are assigned probabilities which are used for ranking, and only a bounded number of parallel alternatives are pursued. Simple bounds on the model straightforwardly predict the recency effects often attributed only to connectionist-based models (Stevenson, 1994; Macdonald et al, 1884; Kempen and Vosse, 1987). In contrast with several current models, the combination of weights in CMMs is motivated directly by probability theory. The parameters of the model are acquired automatically from a corpus, and there are relatively few stipulations about how probabilities are combined (contra Jurafsky, 1996; Tanenhaus et al, in press). An important cognitive parameter concerns the number of analyses which are maintained in parallel. We will present results of experiments which evaluate the performance of the model for both general language processing, and on several critical ambiguities where human performance is well understood. The model is a first step in exploring the role of optimal models of human linguistic performance, as motivated by Chater, Crocker, and Pickering (1998). Recently, Pickering, Traxler and Crocker (to appear) have provided experimental evidence which challenges a pure maximum likelihood model of syntactic ambiguity resolution.

Following the basic assumptions of lexicalist syntax, I claim that Fox preverb-verb combinations are indeed morphologically derived and that inflectional affixes are attached to complex morphological objects in the word-formation component already. In order to account for the syntactic effects, I propose an analysis in Linearisation HPSG (Reape, 1994, Kathol, 1995), which builds on the assumption that Fox preverb-verb complexes introduce more than one domain object into syntax (cf.

Instead, I claim that surface-syntactic linearisation constraints will relate clitic placement directly to a class of lexical items, which in turn is defined on the basis of semantic properties. Therefore, an integrated model of syntax and semantics is called for which builds on highly articulate lexical information. The analysis will, thus, be carried out in the framework of Head-driven Phrase Structure Grammar (HPSG) (Pollard and Sag, 1987; 1994), using multiple inheritance type hierarchies and linearisation constraints. The paper is organised as follows: in the first section, I shall briefly describe the basic empirical observations regarding EP proclisis. In section two, I shall review the empirical problems faced by previous (mostly syntactic) approaches. Section three provides the details of the proposal, starting with a semantic typology of proclisis licensors. In the remainder of the section, I outline the surface-syntactic constraints which define the phenogrammatical relation between licensor and licensee, analysing EP proclisis in an essentially similar way to English negative polarity items (NPI) (cf.

Motivated by the rigorous application of the diagnostic criteria suggested in Zwicky and Pullum (1983) and Miller (1992), clitics in Romance languages are treated as lexical afixes, whose morphological and morphosyntactic properties are derived entirely within the lexicon (Miller and Sag 1997; Monachesi (1996). Weak pronominals in Polish (Kupsc 1999) and second position clitics in Serbo-Croat (Penn 1999), however, enjoy a much higher degree of syntactic transparency, favouring an analysis in terms of linearisation approaches. In this paper, I will suggest that European Portuguese (EP) represents a transitional type, where clitics have already acquired the morphological properties of lexical affixes, yet, ``the rules governing clitic placement seem to relate more to syntax than to prosody or morphology'' (Spencer 1991, p. 365).

As a result, there is a vast body of evidence in French and Italian (Miller 1992; Miller and Sag, 1997; Monachesi, 1996) that weak pronominals in these languages resemble ordinary bound affixes much more than true postlexical clitics. In particular, syntactic, semantic, morphological, and phonological criteria jointly militate against the view of Romance clitics as proper inhabitants of the syntactic world. As a side effect, the distinction between lexical affixes and postlexical clitics (Halpern, 1995) is seen as a strict dichotomy, with little or no room for true morpho-syntactic hybrids. I will argue in this paper that transitional types do indeed occur, which are characterised by the fact that one group of criteria (e.g. morphological criteria) positively suggest syntactic opacity, while almost all syntactic criteria demand a degree of transparency. Based on data from clitic placement and coordination, however, I will suggest that the syntactic transparency is highly superficial in nature, and thus favours an account in terms of word order variation.

The ID tree is non-projective, and even non-ordered, and its edges are labeled by syntactic roles. The LP tree is projective, partially ordered, and its edges are labeled by topological fields. The shape of the LP tree is a flattening of the ID tree's obtained by allowing nodes to 'climb up'.

Aside from the mainstream, linguists in Eastern Europe and Japan have pursued an approach to syntax which seemed better suited for the analysis of freer word order languages: dependency grammar. The key asset of dependency grammar is that it allows for a clean separation of syntactic dependency and surface word order. Unfortunately, none of the frameworks for dependency grammar has really caught on. We suggest two reasons for their failure: 1. many of the dependency-based frameworks lack proper formalization and, perhaps surprisingly, 2. most of them lack a realistic and workable account of word order. In this thesis, we try to remedy these problems in the setting of a constraint-based approach to dependency grammar based on (Duchier 1999). We present a new account of word order for dependency grammar couched in a declarative grammatical formalism called Topological Dependency Grammar (TDG). TDG allows to cleanly separate the two levels of syntactic dependency and surface word order, which greatly facilitates the conception of grammars for freer word order languages. In addition, we can efficiently parse with TDG grammars: using a reduction described in (Duchier 2000), we achieved an efficient parser implementation using modern constraint programming techniques.}, Year = {2001} } @inproceedings{ Declerck:1996:MIP, Author = {Declerck, Thierry}, Title = {Modeling Information-Passing within the LFG-Workbench}, BookTitle = {Proceedings of the 1st Annual Lexical-Functional Grammar Conference}, Address= {Grenoble, France}, CoLiURL = {Declerck:1996:MIP.pdf Declerck:1996:MIP.ps}, URL = {ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/declerck96_lfg.entry ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/declerck96_lfg.ps.gz}, Year = {1996} } @inproceedings{ Declerck:1996:DCS, Author = {Declerck, Thierry}, Title = {Dealing with Cross-Sentential Anaphora Resolution in ALEP}, BookTitle = {Proceedings of the 16th International Conference on Computational Linguistics (COLING'96), August 5-9}, Volume = {1}, Address= {Copenhagen, Danmark}, Pages = {280-285}, CoLiURL = {Declerck:1996:DCS.pdf}, URL = {http://www.dfki.de/dfkibib/publications/docs/Declerck_1996_DCCSARA.pdf}, Abstract = {The experiments described here have been done in connection with the LSGRAM project, which is concerned with the development of large scale grammars and thus foreseen the coverage of "real life texts''.

The resolution of crosssentential anaphora is one of the problems we have to deal with, when we switch towards the analysis of such larger linguistic units. In order to propose an analysis of the crosssentential anaphora, one has to be able to refer back to an antecedent, which is to be found in a preceding sentence. This will be done on the basis of an informationpassing framework. Using also the simple unification technique a resolution of the pronoun can then be tried out: parts of the content information of the pronoun are going to be compared (unified) with specific parts of the content information of the (possible) antecedent.}, Year = {1996} } @inproceedings{ Declerck:1997:IRL, Author = {Declerck, Thierry}, Title = {Investigation on the Reusability of LFG-Based Grammar Resource}, BookTitle = {Proceedings of the 2nd Annual Lexical-Functional Grammar Conference}, Address= {San Diego, USA}, CoLiURL = {Declerck:1997:IRL.pdf Declerck:1997:IRL.ps}, URL = {ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/declerck97_lfg.entry ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/declerck97_lfg.ps.gz}, Year = {1997} } @inproceedings{ Declerck:1997:IBT, Author = {Declerck, Thierry}, Title = {An Interface between Text Structures and Linguistic Descriptions}, BookTitle = {Proceedings of the Datalingvistisk Forening (DALF'97), June 9-10}, Editor = {Christoffersen, Ellen and Music, Bradley}, Address= {Kolding, Denmark}, Pages = {8-22}, CoLiURL = {Declerck:1997:IBT.pdf Declerck:1997:IBT.ps}, URL = {ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/declerck97_dalf.ps.gz}, Abstract = {This paper describes various uses of the Text Handling to Linguistic Structure (TH-LS) component of the Advanced Linguistic Engineering Platform (ALEP).

But reinterpretation phenomena can also be regarded as a gateway for linguistic change, since they may get conventionalized and thus enlarge the domain of compositional semantics. Analyzing reinterpretation will therefore also provide insights into mechanisms of linguistic change. The proposed account of reinterpretation goes as follows. Semantic construction yields ambiguous structures for reinterpretation cases, which are then monotonically enriched with information from extralinguistic sources (e.g. world knowledge).

The exploitation of linguistic knowledge for adding additional constraints (e.g. word order, selectional restrictions) to the grammar may indeed help disambiguation, but it also rules out some perfectly grammatical non-ambiguous strings. Ways out of this dilemma are discussed in this paper. They include - reliance on processin g strategies without addition of additional knowledge - processing guided by statistical probability - leaving desambiguation to external knowledge sources - using additional constraints only if they are needed for disambiguation. We propose the addition of preference values to typed ferature structures. Using preference values has the effect that violation of the additional constraints needed for disambiguation only decreases the preference value, but does not make the sentence unacceptable. Disambiguation is achieved by selecting the reading with the highest preference value. We think that it is possible to define a processing strategy (preference-driven linguistic deduction) that finds the preferred reading first.}, Year = {1992} } @techreport{ Erbach:1992:HDLb, Author = {Erbach, Gregor}, Title = {Head-Driven Lexical Representation of Idioms in HPSG}, Address = {Saarbrücken}, Institution = {Universität des Saarlandes}, Number = {22}, Type = {CLAUS-Report}, Month= {May}, Abstract = {This paper is concerned with the lexical representation of idioms.

A lexical representation for idioms in Head-driven Phrease Structure Grammar (HPSG) is proposed, which can account for the syntactic variability found in idiomatic constructions, and for the non-compositional semantics of idioms. Since all idioms, which are not completely fixed, consist of a lexical head and "frozen" complements, the information about an idiomatic expression can be encoded in the subcategorization list of the idiom's lexical head. Since idioms in volve selection for particular lexemes, a feature is added to HPSG signs to encode this lexemic information. It will be argued that the Locality Principle of HPSG is too strong because it prohibits the representation of idioms proposed in this paper, and that the Semantics Principle must be modified.

Grammars are treated as a definite clause programs, to which program transformation and deduction techniques can be applied. In particular, the view of constraint logic programming is adopted, which abstracts away from the handling of constraints (which is regarded as a service provided by the constraint solver) and concentrates on resolution strategies. The contributions of the thesis are the following: A constraint language supporting sorted feature terms, Prolog terms, multi-dimensional inheritance, finite domains, by compilation to Prolog terms. The constraint language has been extended with external constraint solvers for set constraints, LP constraints, guarded constraints. A partial deduction system for compiling a principle-based grammar into a set of grammar rules. Partial deduction can be applied selectively through control information in the program, which makes it possible to do experimental work in order to determine the selection of goals to which partial deduction is best applied in order to bring the greatest performance improvement.

Bottom-up Earley deduction is better suited for handling discontinuous constituency than its top-down counterpart, it allows best-first search based on bottom-up information (e.g. tag probabilities), and provides different indexing schemes for different modes of combination of items. The correctness, completeness and termination properties of the algorithm have been shown. A generalised linguistic deduction system, which allows combination of different deduction strategies via control annotations, and which is tightly integrated with the underlying programming language in order to achieve efficiency.

Collocational phenomena in general are characterized by restricted lexical selection of the collocation partners. First a characterization of idioms and support verb constructions is given, and idioms and support verb constructions are differentiated from "compositional collocations''. "Compositional collocations" differ from idioms and support verb constructions as the meaning of a "compositional collocation" is derived by the usual compositional semantic functions from the meanings of its constituents, and their syntactic properties are similar to non collocational constructions. Further syntactic and semantic properties of idioms and support verb constructions are described. Unanalyzable and metaphorical idioms are distinguished. While unanalyzable idioms are diachronical often derived from metaphors, a metaphorical interpretation is no longer possible, and their meaning must be listed in the lexicon. In case of metaphorical idioms, where each part must be assigned a (metaphorical) meaning, the meaning of the parts either must be assigned in the lexicon or metaphorization rules must be stated in the grammar. Support verb constructions, which consist of a verb (the support verb) and a noun phrase including the nominal collocation partner (the predicative noun) of the verb, function as predicates and differ from idioms in the ability to express different phases of a process via Aktionsart, and the ability to express causative as well as non causative variation. Both idioms and support verb constructions allow for different degrees of syntactic variation and internal modification. There are some idioms and support verb constructions which are completely fixed. The majority, however, allows for considerably more flexibility such as passivisation, or flexibility in word order, heads and complements need not be adjacent. Due to this simmilarity, we have made an attempt to treat idioms and support verb constructions in a simmilar way. HPSG, as it stands, is not well equipped to handle lexical selection. We have argued that in case of totally fixed idioms a representation of multi-word lexemes with the specification of the PHON feature is appropriate. For idioms which consist of a head and a "frozen" complement and support verb constructions we proposed to handle the relationship between the head and the "frozen" complement or predicative noun, respectively, by subcategorization. Depending on how fixed the "frozen" complement or predicative noun is, either the PHON feature, the DAUGHTERS feature or the newly introduced INDEX feature LEXEME is specified. As a consequence, we subcategorize for feature structures of type SIGN instead of SYNSEM. We have specified the semantics of idioms in the syntactic head of the construction. The semantics of the "frozen" complement is ignored, and the Quantifier Inheritance Principle is modified so that quantification over the "frozen" complement is avoided. The semantic core of the support verb construction is inherited from the predicative noun; in general the support verb adds the Aktionsart and possibly information about the causative relation. The support verb fills one of its argument positions with the predicative noun, and its other argument positions with arguments of the predicative noun. Any remaining arguments of the predicative noun are appended to the SUBCAT list of the support verb. In case of causative support verb constructions, one argument position of the support verb is filled by the cause(r).}, Year = {1993} } @incollection{ Erbach:1994:ISV, Author = {Erbach, Gregor and Krenn, Brigitte}, Title = {Idioms and Support Verb Constructions in HPSG}, BookTitle = {Grammar in HPSG CSLI Lecture Notes}, Editor = {Nerbonne, John and Netter, Klaus and Pollard, Carl J.}, Address = {Stanford}, Publisher = {Center for the Study of Language and Information}, Pages = {365-396}, Year = {1994} } @inproceedings{ Erbach:1995:VFL, Author = {Erbach, Gregor and Manandhar, Suresh}, Title = {Visions for the Future of Logic-Based Natural Language Processing}, BookTitle = {Proceedings of the ILPS'95 Workshop "Visions for the Future of Logic Programming - Laying the Foundations for a Modern Successor to Prolog", December 8}, Address= {Portland, USA}, CoLiURL = {Erbach:1995:VFL.pdf Erbach:1995:VFL.ps}, URL = {ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/ilps95.ps.gz ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/ilps95.entry}, Year = {1995} } @article{ Erbach:1994:RGRb, Author = {Erbach, Gregor and Moshier, M.

In NLP systems which use constraint-based grammars the operation of unification typically plays a central role. Accordingly, the central concern of this thesis is to propose an approach to robust unification. The first part of the thesis underlines the importance of robustness in NLP, provides an overview of the sort of phenomena that require it, and reviews the state of the art. From this, it appears that no methods currently exist for robust processing with grammars of any real linguistic sophistication. The class of constraint-based grammars studied here is that based on Typed Feature Logic (TFL), of which Head-Driven Phrase Structure Grammar is the instance chosen for exemplification. The formalism is described in the second part of the thesis. Grammars based on TFL involve the notion of a signature, which defines the kinds of objects (types) assumed to exist in the grammar. Processing typically involves combining information about pieces of the input by unification. From this perspective, the need for robustness can be seen as arising because pieces of the input provide information which is inconsistent with information from other pieces of the input and/or from the grammar. The first inconsistency is tolerated --- it does not violate the grammar --- and processed using "robust types" which are created by extending the signature to a lattice. Inconsistency with the grammar on the other hand is punished by stripping away the offending information. Weights, added to it on the basis of the grammar, also disappear, thus making the ungrammaticality measurable. The conceptual and formal apparatus for this is developed and exemplified in the third part of the dissertation.}, Year = {2003} } @inproceedings{ Frank:2001:TCC, Author = {Frank, Anette}, Title = {Treebank Conversion.

The conversion and grammar extraction process imports linguistic generalisations that are missing the in original treebank. This supports the extraction of a linguistically sound grammar with maximal generalisation, as well as grammar induction techniques to capture unseen data in stochastic parsing. We further illustrate the flexibility of our conversion method by deriving an alternative representation in terms of topological field marking from the NEGRA treebank, which can be used as input for stochastic topological parsing approaches.

Its syntactic analysis is challenging, since the subject (Jaeger, man) is realised in the middle field in the left conjunct, and is thus - under standard analyses of constituent coordination - not accessible from within the second conjunct, which is missing a subject (hence "subject gap").

Nimmt man den Deckel ab und ruehrt die Fuellung um, steigen Daempfe auf. Takes one the cover off and stirrs the stuffing, steam rises. If one takes the cover off and stirrs the stuffing, steam will rise. SGF constructions have been analysed in terms of asymmetrically embedded conjuncts (Wunderlich 1988, Hoehle 1990, Heycock and Kroch 1993, Buering und Hartmann 1998) or symmetric conjuncts (Steedman 1990, Kathol 1995,1999). Asymmetric embedding is problematic as it involves extraction asymmetries, or a doubtful analysis of coordination as adjunction. Symmetric analyses assume special licensing conditions which are not independently motivated. Especially the word order conditions of Kathol's analysis lack any independent syntactic motivation, and fail to account for related asymmetric coordinations of verb-last and verb-fronted (VL/VF) sentences (2).

We present a multi-factorial LFG analysis of asymmetric constructions (1) and (2), which relies on independently motivated principles of the correspondences between c-structure, f-structure, and i-structure (information structure). SGF coordination is analysed as symmetric coordination in c-structure. Binding of the (prima facie) inaccessible subject of the first conjunct is enabled, at the level of f-structure, by asymmetric projection of a "grammaticalised discourse function GDF", a topic or subject function (Bresnan, 2001). "Asymmetric GDF projection" is motivated by relating the semantic and discourse-functional properties of asymmetric coordination to well-known discourse subordination effects of modal subordination. In conjunction with word order constraints in the optimality model of (Choi 1999, 2001), our analysis explains some mysterious word order constraints as well as some puzzling scoping properties.}, Year = {2002} } @inproceedings{ Frank:2001:LBS, Author = {Frank, Anette and van Genabith, Josef}, Title = {LL-based Semantics for LTAG - and what it teaches us about LFG and LTAG}, BookTitle = {Proceedings of the 6th International Lexical Functional Grammar Conference (LFG'01), June 25-27}, Editor = {Butt, Miriam and Holloway King, Tracy}, Address= {Hong Kong}, Publisher = {CSLI Online Publications}, CoLiURL = {Frank:2001:LBS.pdf}, URL = {http://csli-publications.stanford.edu/LFG/6/lfg01frankgenabith.pdf}, Abstract = {We review existing appoaches to semantics construction in LTAG (Lexicalised Tree Adjoining Grammar) based on the notion of derivation (tree)s.

Linear Logic based "glue semantics", as developed within the LFG framework (cf. Dalrymple (1999)), allows for flexible coupling of syntactic and semantic structure. We investigate application of glue semantics to LTAG syntax, using as underlying structure the derived tree, which is more appropriate for principle-based semantics construction. We show how Linear Logic based semantics construction helps to bridge the non-isomorphism between syntactic and semantic operations in LTAG. The glue approach captures non-tree local dependencies in control and modifcation structures, and extends to the treatment of scope ambiguity with quantified NPs and VP modifers. Finally, glue semantics applies successfully to the adjunction-based analysis of long-distance dependencies in LTAG, which differs signifcantly from the f-structure based analysis in LFG.}, Year = {2001} } @incollection{ Frank:2002:TLS, Author = {Frank, Anette and Zaenen, Annie}, Title = {Tense in LFG: Syntax and Morphology}, BookTitle = {How we say WHEN it happens.

The discourse intonation features focused on are denial and convergence. It has been observed that for German denial can be integrated into discourse-listing through intonation: Ja-acknowledge and Nein-/Ne-denial moves are both manifested by intonation rises. For Bulgarian, intonation rises in answering moves occur only in the acknowledge subtype: rises in denials (Ne-) are associated with uncertainty and surprise. The HG Ne- and SB Ne-moves are resynthesized by means of PSOLA, twelve stimuli being obtained for SB and sixteen for HG. Two appropriate contexts marked for discourse-listing and follow-up moves are excerpted from the MAP Task and are included in perceptual tests whereby native speakers are asked to determine the appropriateness of each stimulus in relation to each context. 'The results for Bulgarian contradict our preliminary observations. Convergence is defined as the matching of corresponding movements in pitch ranges and signals sympathetic agreement with the other speaker’s point of view. The check: answer move sequence can be viewed as instantiating convergence and exemplifies both lexical and Fo movement repetition, especially where ellipted moves are concerned. The two resynthesized sequences for HG and SB respectively are ”Im Westen” and ”Pravo nagore” as manifested in check and answering contexts. As above, native speakers are expected to determine the appropriateness of each stimulus in relation to each context. It has been observed that the differences between checks and answering moves for both HG and SB are phonetically manifested and are also established as being relevant by the perceptual tests, yet they cannot be accounted for phonologically by tone alignment: convergence seems to attenuate the phonological differentiation between checks and answering moves.}, Year = {1999} } @book{ Haider:1991:RDT, Editor = {Haider, Hubert and Netter, Klaus}, Title = {Representation and Derivation in the Theory of Grammar}, Publisher = {Kluwer Academic Publishers}, Address = {Dordrecht}, Series = {Studies in Natural Language and Linguistic Theory}, Volume = {22}, Year = {1991} } @incollection{ Hajicova:1997:NT, Author = {Hajicová, Eva and Kruijff-Korbayová, Ivana}, Title = {On the Notion of Topic}, BookTitle = {Prague Linguistic Circle Papers}, Editor = {Hajicová, Eva and Hoskovec, Tomás and Leška, Oldrich and Sgall, Petr and Skoumalová, Zdena}, Address = {Amsterdam}, Publisher = {John Benjamins Publishers}, Volume = {3}, Pages = {225-236}, Year = {1997} } @inproceedings{ Hajicova:1998:SD, Author = {Hajicová, Eva and Kruijff-Korbayová, Ivana and Kruijff, Geert-Jan M.}, Title = {Salience in Dialogues}, BookTitle = {5th International Congress of the International Association of Dialogue Analysis, April 17-20}, Editor = {Cmejrková, S. and Hoffmannová, J. and Müllerová, O. and Svetlá, J.}, Volume = {1}, Address= {Prague, Czech Republic}, Publisher = {Max Niemeyer Verlag}, Pages = {381-393}, URL = {http://www.coli.uni-sb.de/~korbay/Publications/dialog.ps.gz}, Year = {1998} } @incollection{ Hajicova:1999:PDT, Author = {Hajicová, Eva and Kruijff-Korbayová, Ivana and Sgall, Petr}, Title = {Prague Dependency Treebank: Restoration of Deletions}, BookTitle = {Text, Speech and Dialogue - Second International Workshop, TSD'99, Plzen, Czech Republic, September 1999}, Editor = {Matousek, Václav and Mautner, Pavel and Ocelíková, Jana and Sojka, Petr}, Address = {Berlin}, Publisher = {Springer}, Volume = {1692}, Pages = {44-49}, CoLiURL = {Hajicova:1999:PDT.pdf}, URL = {http://shadow.ms.mff.cuni.cz/pdt/Corpora/PDT_1.0/References/tsd99-deletion.pdf}, Year = {1999} } @phdthesis{ Hansen:2002:NTT, Author = {Hansen, Silvia}, Title = {The Nature of Translated Text - An Interdisciplinary Methodology for the Investigation of the Specific Properties of Translations}, Address = {Saarbrücken, Germany}, School = {Institute for Applied Linguistics - Translation and Interpreting, Saarland University}, Year = {2002} } @inproceedings{ Hansen:2002:CET, Author = {Hansen, Silvia and Teich, Elke}, Title = {The creation and exploitation of a translation reference corpus}, BookTitle = {Proceedings of the First International Workshop on Language Resources for Translation Work and Research (3rd International Conference on Language Resources and Evaluation (LREC-2002)), May 28}, Address= {Las Palmas de Gran Canaria, Spain}, URL = {http://www.coli.uni-sb.de/~hansen/hansen-teich.zip}, Abstract = {While in many branches of linguistics monolingual reference corpora are widely used, e.g., in lexicography, in the construction of grammars and generally in empirical linguistic studies, in translation research as well as translation practice the concept of a parallel refernce corpus has not yet assumed a similarly important role. In our view, this is partly due to a lack of interaction of researchers involved in the development of corpus tools (computational linguistics, humanities computing) and the potential users of such tools in the area of translation (translatology, translation practice). The goal of the present paper is to initiate such an interaction. We present the design of an German-English and French-English translation corpus and explore its use as a reference corpus for translatologists as well as translators. First, we introduce the the basic computational techniques needed to build such a translation reference corpus. These techniques cover the preparation of the corpus as well as its linguistic annotation. In the preparatory step the corpus has to be aligned and encoded. To enrich the corpus with linguistic information, part-of-speech tagging and syntactic parsing have to be carried out for the different languages. Furthermore, to make the parallel reference corpus usable for translation scholars and translators, it has to be searchable, i.e., appropriate query facilities must be provided. We show how to extract instances of linguistic phenomena that are of interest from a translation point of view using a multilingual English-German-French corpus. We explain possible translation procedures for perfect aspect, reduced relative clauses and cleft constructions from English into German and French on the basis of parallel concordances extracted from the translation reference corpus. Finally, we specify some additional requirements to improve the usability of translation corpora in both translation studies and translation practice.}, Year = {2002} } @article{ Hardcastle:1989:APF, Author = {Hardcastle, William J. and Barry, William J.}, Title = {Articulatory and Perceptual Factors in /l/ Vocalisations in English}, Journal = {Journal of the International Phonetics Association}, Volume = {15}, Number = {2}, Pages = {3-17}, Year = {1989} } @article{ Haridi:1999:ELV, Author = {Haridi, Seif and Van Roy, Peter and Brand, Per and Mehl, Michael and Scheidhauer, Ralf and Smolka, Gert}, Title = {Efficient Logic Variables for Distributed Computing}, Journal = {ACM Transactions on Programming Languages and Systems}, Volume = {21}, Number = {3}, Pages = {569-626}, CoLiURL = {Haridi:1999:ELV.pdf Haridi:1999:ELV.ps}, URL = {ftp://ftp.ps.uni-sb.de/pub/papers/ProgrammingSysLab/TOPLAS99.ps.gz}, Abstract = {We define a practical algorithm for distributed rational tree unification and prove its correctness in both the off-line and on-line cases.

Oz appears to the programmer as a concurrent object-oriented language with dataflow synchronization. Logic variables implement the dataflow behavior. We show that logic variables can easily be added to the more restricted models of Java and ML, thus providing an alternative way to do concurrent programming in these languages. We present common distributed programming idioms in a network-transparent way using logic variables. We show that in common cases the algorithm maintains the same message latency as explicit message passing. In addition, it is able to handle uncommon cases that arise from the properties of latency tolerance and third-party independence. This is evidence that using logic variables in distributed computing is beneficial at both the system and language levels. At the system level, they improve latency tolerance and third-party independence.

Yet, writing distributed applications remains difficult because the programmer has to manage models of these areas explicitly. A major challenge is to integrate the four models into a coherent development platform. Such a platform should make it possible to cleanly separate an application's functionality from the other four concerns. Concurrent constraint programming, an evolution of concurrent logic programming, has both the expressiveness and the formal foundation needed to attempt this integration. As a first step, we have designed and built a platform that separates an application's functionality from its distribution structure. We have prototyped several collaborative tools with this platform, including a shared graphic editor whose design is presented in detail. The platform efficiently implements Distributed Oz, which extends the Oz language with constructs to express the distribution structure and with basic primitives for open computing, failure detection and handling, and resource control.

This means that all network operations are invoked implicitly by the system as an incidental result of using particular language constructs. However, since network operations are expensive, the programmer must retain control over network communication patterns. This control is provided through the language constructs. While retaining their centralized semantics, they are extended with a distributed semantics. Distributed Oz is an extension of Oz, a concurrent state-aware language with first-class procedures. Distributed Oz extends Oz with just two concepts: mobility control and asynchronous ordered communication. Mobility control provides for truly mobile objects in a simple and clean way. Asynchronous ordered communication allows to conveniently build servers. These two concepts give the programmer a control over network communications that is both simple and predictable. We give scenarios to show how common distributed programming tasks can be implemented efficiently. There are two reasons for the simplicity of Distributed Oz. First, Oz has a simple formal semantics. Second, the distributed extension is built using network protocols that are natural extensions to the centralized language operations. We discuss the operational semantics of Oz and Distributed Oz and the architecture of the distributed implementation.

This paper focuses on the use and implementation of such abstractions for investigating programmable search algorithms and memory policies in a C++ constraint programming library.}, Year = {1999} } @article{ Henz:1996:CBT, Author = {Henz, Martin and Würtz, Jörg}, Title = {Constraint-Based Time Tabling - A Case Study}, Journal = {Applied Artificial Intelligence}, Volume = {10}, Number = {5}, Pages = {439-453}, Abstract = {In this paper, we concentrate on a typical scheduling problem: the computation of a time table for a German college.

In our view, this is due to the fact that most available tools are oriented towards contributing to a general purpose generation system rather than supporting the economic development of dedicated applications. In order to improve this situation, we present a methodology for developing application-oriented report generation with limited effort, emphasizing domain- and user-specific preferences over general-purpose communicative principles. Key parts in our approach comprise building an ontologically minimal initial representation on the basis of user parameters and associated domain data, the successive refinement of this initial representation by making implicit information explicit enough for fleshing out selected text and sentence patterns, and the opportunistic combination of linguistically motivated methods with template-based generation. This methodology should enable system developers to build application-oriented report generators more systematically and with reduced effort.}, Year = {1998} } @inproceedings{ Huckvale:1989:APF, Author = {Huckvale, Mark A. and Howard, I.

Besides the fact that it satisfies characteristic criteria of 'ambiguous reasoning', the underlying logic is also a suitable candidate as a minimal calculus for this task. Natural extensions of the calculus correspond to intuitive constraints on partial disambiguations.

An important discrepancy that is addressed in this paper is about the implicit assumption what exists. For instance, in the case of universal quantification natural language uses restrictions and presupposes that these restrictions are non-empty, while in classical logic it is only assumed that the whole universe is non-empty. On the other hand, all constants mentioned in classical logic are presupposed to exist, while it makes no problems to speak about hypothetical objects in everyday language. These problems have been discussed in philosophical logic and some adequate many-valued logics were developed to model these phenomena much better than classical first-order logic can do. An adequate calculus, however, has not yet been given. Recent years have seen a thorough investigation of the framework of many-valued truth-functional logics. Unfortunately, restricted quantifications are not truth-functional, hence they do not fit the framework directly. We solve this problem by applying recent methods from sorted logics.}, Year = {1996} } @article{ Kerber:1996:TCP, Author = {Kerber, Manfred and Kohlhase, Michael}, Title = {A Tableau Calculus for Partial Functions}, Journal = {Collegium logicum: Annals of the Kurt-Gödel-Society}, Volume = {2}, Pages = {21-49}, Year = {1996} } @techreport{ Kerber:1997:RBM, Author = {Kerber, Manfred and Kohlhase, Michael}, Title = {Reasoning without Believing: On the Mechanization of Presuppositions and Partiality}, Address = {Birmingham}, Institution = {University of Birmingham, School of Computer Science}, Number = {CSRP-97-23}, Type = {Technical Report}, Month= {September}, CoLiURL = {Kerber:1997:RBM.pdf Kerber:1997:RBM.ps}, URL = {ftp://ftp.cs.bham.ac.uk/pub/tech-reports/1997/CSRP-97-23.ps.gz}, Abstract = {It is well-known that many relevant aspects of everyday reasoning based on natural language cannot be adequately expressed in classical first-order logic. In this paper we address two of the problems, firstly that of so-called presuppositions, expressions from which it is possible to draw implicit conclusion, which classical logic normally does not warrant, and secondly the related problem of partiality and the adequate treatment of undefined expressions. In natural language, presuppositions are quite common, they can, however, only insufficiently be modeled in classical first-order logic. For instance, in the case of universal quantification one normally uses restrictions in natural language and presupposes that these restrictions are non-empty, while in classical logic it is only assumed that the whole universe is non-empty. On the other hand, all constants mentioned in classical logic are presupposed to exist, while it makes no problems to speak about hypothetical objects in everyday language. Similarly, undefined expressions can be handled in natural language discourses and utterances are not only classified into the two categories 'true' and 'false'. This has led to the development of various better-suited many-valued logics. By combining different approaches we can now give a static description of presuppositions and undefinedness within the same framework. Additionally, we have developed an efficient mechanization of the induced consequence relation (which has been missing in the literature) by combining methods from many-valued truth-functional logics and sort techniques developed for search control in automated theorem proving.}, Year = {1997} } @techreport{ Kiefer:1995:FIG, Author = {Kiefer, Bernd and Fettig, Thomas}, Title = {FEGRAMED - An Interactive Graphics Editor for Feature Structures}, Address = {Saarbrücken}, Institution = {DFKI}, Number = {RR-95-06}, Type = {Research Report}, CoLiURL = {Kiefer:1995:FIG.pdf Kiefer:1995:FIG.ps}, URL = {ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/fegramed.ps.gz ftp://ftp.dfki.uni-kl.de/pub/Publications/ResearchReports/1995/RR-95-06.ps.gz}, Abstract = {This paper describes a tool for supporting grammar development in those linguistic frameworks which employ some constraint-based formalism, such as LFG (Lexical Functional Grammar), HPSG (Head-Driven Phrase Structure Grammar), FUG (Functional Unification Grammar) and CUG (Categorial Unification Grammar).

During grammar processing, feature structures can become quite large (up to several thousand nodes), such that a customized view of the feature structure, which allows to selectively focus on relevant parts, becomes essential.

The purpose of the corpus is to support the diagnosis of errors in the syntactic components of natural language processing (NLP) systems. Two secondary aims are the evaluation of NLP systems components and the support of theoretical and empirical work on German syntax. The data consist of artificially and systematically constructed expressions, including also negative (ungrammatical) examples. The data are organized into a relational data base and annotated with some basic information about the phenomena illustrated and the internal structure of the sample sentences. The organization of the data supports selected systematic testing of specific areas of syntax, but also serves the purpose of a linguistic data base. The paper first gives some general motivation for the necessity of syntactic precision in some areas of NLP and discusses the potential contribution of a syntactic data base to the field of component evaluation. The second part of the paper describes the set up and control methods applied in the construction of the sentence suite and annotations to the examples.

The numbers of readings of different ambiguous components of a sentence or discourse multiply over all these components, yielding a number of readings that can be exponential in the number of ambiguities. Both from a computational and a cognitive point of view, it seems necessary to find small representations for ambiguities that describe all readings in a compact way. This approach is called underspecification, and it has received increasing attention in the past few years. Lately, two particularly elegant formalisms for the underspecified treatment of scope ambiguities in semantics have been proposed: Context Unification and the Constraint Language for Lambda Structures, CLLS. Common to both is that they regard the term representing the semantics of a sentence as a tree and describe it by imposing tree constraints. Furthermore, both offer the expressive power to describe simple ellipses and their interaction with scope ambiguities. This thesis investigates some formal properties of these two formalisms. It examines their relation and shows that, except for a few additional constructs of CLLS, both languages are equivalent in expressive power. In terms of computational complexity, this gives us the immediate result that the complexity of the satisfiability problem of CLLS is exactly the same as that of context unification, which, unfortunately, is unknown. The thesis further investigates the complexity of the satisfiability problem of dominance constraints, an important sublanguage of CLLS, and shows that it is NP-complete. In the course of the discussion of complexity, it also briefly explains how techniques from concurrent constraint programming can be applied to implement solution algorithms for these formalisms.}, Year = {1999} } @proceedings{ Koller:2002:PSR, Editor = {Koller, Alexander and Mann, Gideon}, Title = {Proceedings of the Student Research Workshop at ACL-02, July 7-12}, Address= {Philadelphia, Pennsylvania, USA}, Year = {2002} } @inproceedings{ Koller:2000:PTF, Author = {Koller, Alexander and Mehlhorn, Kurt and Niehren, Joachim}, Title = {A Polynomial-Time Fragment of Dominance Constraints}, BookTitle = {38th Annual Meeting of the Association of Computational Linguistics (ACL '00), October 1-8}, Address= {Hong Kong}, CoLiURL = {Koller:2000:PTF.pdf Koller:2000:PTF.ps}, URL = {ftp://ftp.ps.uni-sb.de/pub/papers/ProgrammingSysLab/poly-dom.ps.gz}, Abstract = {Dominance constraints are a logical language for describing trees that is widely used in computational linguistics.

Our aim is to propose a unified linking account of the MG ESPVCs. This unified account 1. is based on the assumption that the individual denoted by the object NP (or PP) of the MG ESPVCs is entailed to be semantically underspecified, and 2. makes use of Wechsler's (1995) Notion Rule, Davis and Koenig's (2000) linking theory, as well as Markantonatou and Sadler's (1996) proposal for the linking of indirect arguments.}, Year = {2001} } @inproceedings{ Kordoni:2001:OLM, Author = {Kordoni, Valia}, Title = {Optimal Linking for Modern Greek Psych Verb Constructions}, BookTitle = {Proceedings of the 6th International Lexical Functional Grammar Conference (LFG'01), June 25-27}, Editor = {Butt, Miriam and Holloway King, Tracy}, Address= {Hong Kong}, Publisher = {CSLI Publications}, Pages = {184-200}, CoLiURL = {Kordoni:2001:OLM.pdf}, URL = {http://cslipublications.stanford.edu/LFG/6/lfg01kordoni.pdf}, Abstract = {This paper focuses on the semantic properties and the syntactic behaviour of MG ESPVCs like the following: I Maria fovate tis kategides. the Maria.N fear.3S the storms.A "Mary is afraid of the storms."

In most state-of-the-art automatic speech recognition (ASR) systems, however, phonetic features do not play any role. The statistical models for each phone or phoneme are based on a spectral parameterisation of the signals, like mel-frequency cepstral coefficients (MFCC's) and energy. Three questions are dealt with in this paper: Can we successfully bridge this gap between phonological theory and ASR by using phonetic features in ASR? Which phonetic feature set is most appropriate for ASR? Can we attain the same result by using more complex non-linguistic modelling? 1. PHONETIC FEATURES IN ASR To bridge the gap between phonologists' formal representation of the phoneme and the almost purely acoustic description of the signal used in ASR systems, we have used phonetic features to create statistical phone models for automatic speech recognition. The phonetic features were derived from the spectral representation of the signal used in most standard ASR systems (MFCC's + energy) by means of a neural network. Not only do we find a clear increase in the phoneme identification rate (see under 2 below) [1], the confusions between phonemes are also much easier to interpret, since phonemes which are confused are usually very similar in terms of the phonetic features they are made up of. This is not the case when acoustic parameters are used to create phoneme models [2]. 2. DIFFERENT PHONETIC FEATURE SETS It is not self-evident which set of phonetic features is most appropriate to describe phonological categories and the processes that operate on them, since the various feature theories have different phonological implications. To evaluate how appropriate the different feature sets are for application in an ASR system, we have used several different feature sets, both articulatory-phonetic (IPA) and phonological (SPE) [3]. We have so far compared the phoneme identification results for both underspecified and fully specified SPE features with those for the set of features used in the IPA to distinguish all phonemes. In addition, the results were compared to those in a standard ASR system using acoustic parameters (MFCC's) directly to create phone models. We found a clear improvement in the phoneme identification rate when phonetic features were used to model the phones, in comparison to directly using acoustic parameters. Underspecified SPE features led to the best performance (for multi-language Eurom0 data, without the use of a lexicon or language model) of all: acoustic parameters: 15.6% IPA features: 42.6% SPE features: 36.2% Underspecified SPE features: 46.1% In addition to the features sets reported so far, the phoneme identification results for articulatory features [4] will be reported and their relative merits will be discussed. 3. VARIATION MODELLING VERSUS LINGUISTIC MODELLING The acoustic-phonetic mapping in a neural network combines two advantages, namely 1) variation modelling: different acoustic realisations of the same phoneme (e.g. allophonic variants) can be discerned by the neural network 2) linguistic modelling: these different realisations are mapped onto more homogeneous, distinctive features Even if the neural network can reduce the variation in the input parameters for statistical modelling by mapping different acoustic realisations of a phoneme onto phonetic features, the question remains whether the same result can be reached by using a non-linguistic approach. Variation modelling can also be achieved by using more complex acoustic phoneme models (multiple mixtures per state in HMM), so that we do not necessarily have to make a mapping onto phonetic features to achieve this goal. A comparison of the performance of a standard system which does not use phonetic features with the performance of a system in which phonetic features are used to train the phoneme models shows the merits of using a signal representation derived from phonological theory.}, Year = {2000} } @article{ Koreman:1997:RPF, Author = {Koreman, Jacques and Andreeva, Bistra and Barry, William J.}, Title = {Relational Phonetic Features for Consonant Identification in a Hybrid ASR System}, Journal = {PHONUS}, Volume = {3}, Pages = {83-110}, CoLiURL = {Koreman:1997:RPF.pdf}, URL = {http://www.coli.uni-sb.de/Phonetics/Research/PHONUS_research_reports/Phonus3/Koreman_PHONUS3.ps.gz}, Abstract = {In this article we discuss implementation of some fundamental phonetic ideas related to what we shall call "relational processing" in a cross-language consonant identification system. The term relational processing refers to the way vowel transitions play a role in the identification of neighbouring consonants. Two experiments are described: first, consonant identification results from a hidden Markov modelling experiment are presented for consonants plus the preceding and following vowel transitions, if present. The results are compared to a baseline experiment, in which the vowel transitions are not used in the identification of the consonants. In the second experiment, the acoustic parameters are first mapped onto phonetic features; this mapping is performed by a Kohonen network1. Since vowel transitions are considered to be particularly important for identification of the place of articulation of the neighbouring consonant, only the place features (and not the consonants' manner features or the phonetic features of the vowel to which the transitions belong) are derived for the vowel transitions. Separate hidden Markov models are trained for the consonants, for the vowel offset and vowel onset transitions which share all consonantal place-of-articulation features. Concatenations of these models form the phone-like recognition units (comparable to the concatenation of phone models for the recognition of words in a conventional ASR system) which are later used for consonant identification. The results are compared with a baseline experiment in which no acoustic-phonetic mapping is performed. The experiments show that relational processing improves the consonant identification results.}, Year = {1997} } @inproceedings{ Koreman:1998:AAP, Author = {Koreman, Jacques and Andreeva, Bistra and Barry, William J.}, Title = {Die Abbildung Akustischer Parameter auf phonetische Merkmale in der automatischen Spracherkennung}, BookTitle = {Computer, Linguistik und Phonetik zwischen Sprache und Sprechen : Tagungsband der 4.

The phonetic features are derived from acoustic parameters by means of Kohonen networks. Behind the use of phonetic features instead of standard acoustic parameters lies the assumption that it is useful to help the system to focus on linguistically relevant signal properties. Previous experiments using very simple hidden Markov models to represent the phones (with only one mixture for each state and without a lexicon or language model) have indeed shown that the phoneme identification rates on the basis of phonetic features were considerably higher than on the basis of acoustic parameters. When eight mixtures per state are used in hidden Markov modelling, the phoneme identification rates for three different sets of phonetic features were found to be lower than those obtained from a system in which the acoustic parameters are modelled directly. It is suggested that the results are still good enough, however, to further explore the use of phonetic features in a complete automatic speech recognition system: if each phone sequence representing a word in the lexicon is replaced by a sequence of underspecified phonetic feature vectors, the use of phonetic features in the acoustic decoding may have certain advantages.}, Year = {2000} } @inproceedings{ Koreman:1999:APV, Author = {Koreman, Jacques and Andreeva, Bistra and Strik, Helmer}, Title = {Acoustic Parameters Versus Phonetic Features in ASR}, BookTitle = {Proceedings of the 14th International Congress of Phonetic Sciences (ICPhS'99), August 1-7}, Address= {San Francisco, USA}, CoLiURL = {Koreman:1999:APV.pdf Koreman:1999:APV.ps}, URL = {http://lands.let.kun.nl/literature/strik.1999.2.ps}, Abstract = {By mapping acoustic parameters onto phonetic features, it is possible to explicitly address the linguistic information in the signal.

Some of the parameters can distinguish between (some of) the 5 groups regardless of speaker sex, whereas other parameter do so only for male or female voices. The results of this study can be useful for the derivation of parameters which can be used for instance for the evaluation of voice therapy; the results can also indicate parameters which should be given special attention in a pre-screening of speakers with a high risk of developing a voice pathology, since a change in these parameters between consultations at the ENT clinic may indicate a development towards a pathological voice.

The aim was to examine several hypotheses derived from Hawkins' (1994) performance theory. In this context it was crucial to examine whether and to which extend length influences the order of subject and objects. The analysis was based on data extracted from the annotated NEGRA corpus (Skut et al., 1998) and the untagged Frankfurter Rundschau corpus. We developed an analysis system operating on the untagged corpus that facilitates the acquisition of data and subsequent statistical analysis. We describe this system and discuss the results drawn from the analysis of the data. These results do not support the theoretical assumptions made by Hawkins.

The question whether it is a syntactic or a semantic process which provides the missing linguistic material in the complement of WRA comparatives is also given a complex answer: Linguistic context is accessed by combining a reconstruction operation and a mechanism of anaphoric reference.

With this general characterization, we prove completeness of the sequent calculus as well as a uniform relativization of strong completeness under appropriateness conditions. This establishes various completeness theorems from the literature as applications of the results here. To demonstrate the generality of our result, we also prove, by exactly the same technique, the completeness of an intuitionistic version of the calculus with respect to a class of Kripke structures. We next turn to a proof theoretic result that is intimately related to completeness: cut elimination. We prove a version of cut elimination for the classical calculus under appropriateness conditions, and as a corollary that various fragments of the calculus are also sound and strongly complete. Finally, completeness of the fragments allows us to investigate a correspondence between certain information systems and certain calculi.

The part that appears to the left of the main verb in verb final position and that is stranded when the finite verb is in initial position is traditionally called a separable prefix. Since prefixes are by definition not separable, the terms particle and preverb are used in more recent work. (1) a. Setzt der Fährmann Karl über? takes the ferryman Karl across 'Does the ferryman take Karl across?' b. daß der Fährmann Karl übersetzt. that the ferryman Karl across.takes In (1a), where the verb is in initial position, the preverb is stranded. Below I will argue that separable verbs in German behave like other elements in the predicate complex. This view is supported by the following facts: Preverbs are serialized like verbal or predicative adjectival complements in the right sentence bracket (the right periphery of a clause that does not contain extraposed elements), they can be fronted as can be done with single verbs or predicative adjectives. If preverbs are analyzed as part of the predicate complex, the fronting data can be accounted for as an instance of complex fronting (Partial Verb Phrase Fronting (PVP)). The inability of particles and predicates in resultative constructions to co-occur and the non-iterability of preverbs will be explained by the fact that particles and resultative predicates occupy a designated valance position that does not allow more than one particle Grammatical Interfaces in HPSG.}, Year = {2000} } @phdthesis{ Muller:19xx:CPV, Author = {Müller, Stefan}, Title = {Complex Predicates: Verbal Complexes, Resultative Constructions, and Particle Verbs in German}, Address = {Saarbrücken}, School = {Universität des Saarlandes}, Type = {Habilitationsschrift}, Abstract = {In dem Buch entwickle ich eine Theorie der komplexen Prädikate, die normale Kopulakonstruktionen, kohärente Infinitive einschließich der AcI-Konstruktionen, Subjekt- und Objektprädikative, Resultativkonstruktionen und Partikelverben erfaßt. (1) Er fährt das Auto kaputt / zu Schrott. (2) Er ißt das Fleisch roh. Zur Abgrenzung der Resultativkonstruktionen (1) von anderen sekundäre Prädikaten wird auch auf depiktive Prädikate (2) eingegangen und eine entsprechende Analyse für diese entwickelt. Ich zeige, daß depiktive Prädikate als Adjunkte zu behandeln sind, die mit einem Element in der Argumentstruktur des Verbs, das sie modifizieren, koindiziert sind. Ich zeige auch, daß die Elemente in der Argumentstruktur des Verbs je nach ihrer Obliqueness als Antezedenten unterschiedlich gut geeignet sind. Im Teil, der sich mit Partikelverben beschäftigt, argumentiere ich, daß sich Verbzusätze wie andere Teile das Prädikatskomplexes verhalten. Sie werden wie Verben in der rechten Satzklammer angeordnet (3)-(4), können wie Adjektive oder Verben einzeln im Vorfeld stehen (5) oder bei Fokussierung wie Adjektive auch im Mittelfeld links vom Verbalkomplex angeordnet werden. (3) Karl kommt abends in Berlin an. (4) Karl kommt abends in der Stadt an, in der ich wohne. (5) Fest steht, daß Karl nicht der Mörder war. Es scheint also angebracht zu sein, die Verbzusatz-Verb-Konstruktionen syntaktisch wie Verbalkomplexe, also in der Syntax, zu behandeln. Wenn Verbzusätze analog zu anderen Elementen des Verbalkomplexes behandelt werden, kann (5) als Falle von (Partial) Verb Phrase Fronting behandelt werden. Für nicht-transparente Partikelverben nehme ich Lexikoneinträge an, die denen von verbalkomplexbildenden Verben ähneln. Lexikoneinträge, die in transparente Partikelverbkombinationen verwendet werden, werden durch Lexikonregeln lizensiert. Bei Behandlung der Partikeln als eigenständige syntaktische Einheiten stellt sich natürlich die Frage, wie die morphologischen Fakten, insbesondere die Derivation erklärt werden kann. In einer breiten empirischen Untersuchung werden Ähnlichkeiten zur Derivation mit Resultativkonstruktionen aufgezeigt und es wird deutlich gemacht, daß weder bei Resultativkonstruktionen noch bei Partikelverben Listedness für die Derivation entscheidend ist. Produktive Partikel-Verb-Verbindungen und die eindeutig syntaktischen Resultativkonstruktionen treten z.B. in ähnlicher Weise in vielen Nominalisierungsformen auf. Zur Beschreibung von Flexion und Derivation nehme ich Lexikonregeln an, die Stämme auf flektierte Formen bzw. Stämme auf andere Stämme abbilden. Im Fall der Partikelverben wird ein Stamm, der für eine Partikel subkategorisiert ist, durch Flexionsregeln auf ein Wort abgebildet, das dann in der Syntax mit der Partikel kombiniert werden kann. Alternativ kann der Stamm aber auch durch eine Derivationsregel auf einen anderen Stamm abgebildet werden, dieser Stamm muß dann natürlich auch flektiert werden. Da der Stamm für die Partikel subkategorisiert ist, haben Derivationsregeln Zugriff auf Information, die von der Partikel begesteuert wird (z.B. semantische Information bzw. Information über zusätzliche Komplemente zusätzliche Komplemente). Die vieldiskutierten Klammerparadoxa existieren für diesen Ansatz nicht.

The interface is easily extendable to other constraint systems as done for set constraints. Constraints are implemented as instances of C++ classes, so-called propagators. Propagators are completely separated from the runtime system.

Current constraint systems focus on either high-level modeling or efficient implementation technology. While each approach lacks the advantages of the other one, this paper describes the combination of them in the high-level concurrent constraint language Oz. We describe an interface to Oz providing abstractions to program new efficient constraints in CPP, preserving the benefits of Oz for problem modeling. While constraints and the Oz runtime system are linked through the interface, and adequate interface abstractions are supplied to implement advanced algorithmic techniques. In particular, it provides the means to reflect the validity of a constraint and to control and inspect the state of a constraint. This allows the user to solve demanding combinatorial problems, such as hard scheduling problems. It is desirable to execute concurrent constraint programs in parallel to profit from multiprocessor architectures. We discuss how the proposed interface can be adapted to parallel execution, avoiding the recoding of constraint implementations for sequential solvers.}, Year = {1999} } @phdthesis{ Muller-Landmann:2000:CBP, Author = {Müller-Landmann, Sonja}, Title = {Corpus-Based Parse Pruning - Applying Empirical Data to Symbolic Knowledge}, Address = {Saarbrücken}, School = {Universität des Saarlandes, Department of Computational Linguistics}, Year = {2000} } @article{ Muskens:1996:CMS, Author = {Muskens, Reinhard}, Title = {Combining Montague Semantics and Discourse Representation}, Journal = {Linguistics and Philosophy}, Volume = {19}, Pages = {143-186}, Year = {1996} } @techreport{ Muskens:1997:PSC, Author = {Muskens, Reinhard}, Title = {Program Semantics and Classical Logic}, Address = {Saarbrücken}, Institution = {Universität des Saarlandes}, Number = {86}, Type = {CLAUS-Report}, Month= {January}, Pages = {29}, CoLiURL = {Muskens:1997:PSC.pdf Muskens:1997:PSC.ps}, URL = {ftp://ftp.coli.uni-sb.de/pub/coli/claus/claus86.ps ftp://ftp.coli.uni-sb.de/pub/coli/claus/claus86.dvi}, Abstract = {In the tradition of Denotational Semantics one usually lets program constructs take their denotations in reflexive domains, i.e. in domains where self-application is possible.

In the second phase the "frame system" is instantiated by the integration of existing components as well as by defining the particular flow of control between these components. Because of the object-oriented paradigm it is easy to augment the frame system, which increases the flexibility of the whole system with respect to new applications. The development of the COSMA system will serve as an example of this claim.}, Year = {1993} } @inproceedings{ Neumann:1994:AEB, Author = {Neumann, Günter}, Title = {Application of Explanation-Based Learning for Efficient Processing of Constraint-Based Grammars}, BookTitle = {Proceedings of the 10th IEEE Conference on Artificial Intelligence for Applications, March 1-4}, Address= {San Antonio, Texas, USA}, Pages = {208-215}, URL = {ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/ebl.dvi.Z ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/ebl.entry ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/ebl.ps.Z http://www.dfki.de/cl/papers/cl-abstracts.html#ebl.abstract}, Year = {1994} } @phdthesis{ Neumann:1994:UCM, Author = {Neumann, Günter}, Title = {A Uniform Computational Model for Natural Language Parsing and Generation.

Understanding the algorithmic properties of subtype entailment is relevant to several subtype inference systems.

Whether non-structural subtype entailment is decidable is a prominent open problem. We characterize subtype entailment in automata theory. This yields a uniform proof method by which all known complexity results on subtype entailment in the literature can be derived. The main contribution of the paper is an equivalent characterization of non-structural subtype entailment in automata theory (by so called P-automata). On the one hand side, our characterization implies that several variants of non-structural subtype entailment are polynomial time equivalent (with or without contravariant function types or recursive types).

To this end, two recent approaches to the problem will be reviewed and compared, which comparison creates actually the very core of the paper. The first of the appraches to description of crossing dependencies is presented in the paper "On Head Non-Movement" by Pollard. This approach tries to implant the "crossing" into the (syntactic) structure. To achieve this goal, it uses means resulting in changing the intuitive subcategorization requirements of words and phrases involved - actually a non-transformational analog of "raising". The second approach, put forward in the paper by Reape "A Theory of Word Order And Discontinuous Constituency in West Continental Germanic", keeps the immediate dominance relations (expressing subcategorization, among other) intact, and aims at describing the "crossing" phenomena by means of non-concatenative phonology. Unsurprisingly, it can be shown that, in the general case, neither of them is to be considered satisfactory alone, and that only a reasonable combination of the two can be hoped to cover the full range of data. Nevertheless, one of the approaches will be shown to be superior to the other as to description of their syntactically interesting part. Later some refinements and changes of this approach will be proposed (together with their motivations), with the aim of making the theory fit better the empirical data. The sketched approach is illustrated on certain constructions from German and Czech.}, Year = {1991} } @inproceedings{ Oliva:1992:PTW, Author = {Oliva, Karel}, Title = {The Proper Treatment of Word Order in HPSG}, BookTitle = {14th International Conference on Computational Linguistics (COLING '92), August 23-28}, Editor = {ICCL}, Address= {Nantes, France}, Pages = {184-190}, Year = {1992} } @techreport{ Oliva:1992:ELK, Author = {Oliva, Karel}, Title = {Expressing Linguistic Knowledge in STUF'91 (manual of the formalism)}, Institution = {IBM}, Number = {206}, Type = {IWBS Report}, Year = {1992} } @techreport{ Oliva:1992:WOC, Author = {Oliva, Karel}, Title = {Word Order Constraints in Binary Branching Syntactic Structures}, Address = {Saarbrücken}, Institution = {Universität des Saarlandes}, Number = {20}, Type = {CLAUS-Report}, Month= {February}, Abstract = {This paper describes a possibility of expressing ordering constraints among non-sister constituents in binary branching syntactic structures on a local basis, supported by viewing the binary branching structure as a list (rather than a tree) of constituents within HPSG-style grammars.

Further on, we concentrate on the more linguistical aspects of the latter understanding. In particular, we compare the pair of languages Czech and English, whose considerably different status as to the severity of constraints on ordering of elements within a continuous head domain of the finite verb is notorious, and aim this comparison at the possibilities which these languages offer for discontinuity of head domains. In this respect, we demonstrate that the two possible ways of understanding of word order freedom correlate, that is to say that English with its rather fixed order freedom within a continuos head domain also imposes severe constraints on extraction out of these domains, while Czech with its almost free order within a domain is also much more liberal as to extraction.

However, whenever such a grammar is aimed at development of a real world applied project, at least two disadvantages become clear. First, it breaks with the traditional understanding of a grammar as a network of phenomena (such as agreement, subcategorization, etc.), thus impeding the (direct) incorporation of this knowledge into such grammars. Second, a realistic grammar is inevitably huge and simultaneously contains very complex interdependencies among rules. This makes any modularization of grammar engineering (aka division of labour within a team) and above all maintaining and debugging realistic grammars a virtually impossible task. This paper presents an alternative view of formal (computational) grammars of natural language allowing for smooth modularization of the grammarwriting process and hence for meeting the pressing task of distributed grammardevelopment. The examples of both problems and their solutions are related to grammars in HPSG style, however, the problems discussed are in no way HPSG specific, just on the contrary, they indeed concern any approach making use of feature structured categories.}, Year = {1999} } @incollection{ Oliva:1998:PBD, Author = {Oliva, Karel and Petkevic, Vladimir}, Title = {Phenomena-Based Description of Dependency-Syntax: A Survey of Ideas and Formalization}, BookTitle = {Issues of Valency and Meaning - Studies in Honour of Jarmila Panevová}, Editor = {Hajicová, E. and Hladká, B.}, Address = {Praha}, Publisher = {Charles University Press}, Year = {1998} } @mastersthesis{ Oliver:1998:PTS, Author = {Oliver, Dominika}, Title = {Polish Text to Speech Synthesis}, School = {University of Edinburgh}, Year = {1998} } @inproceedings{ Oravecz:2002:ESP, Author = {Oravecz, Csaba and Dienes, Peter}, Title = {Efficient Stochastic Part-of-Speech Tagging for Hungarian}, BookTitle = {Proceedings of the Third International Conference on Language Resources and Evaluation (LREC2002), May 29-31}, Address= {Las Palmas, Canary Islands, Spain}, Pages = {710-717}, CoLiURL = {Oravecz:2002:ESP.pdf Oravecz:2002:ESP.ps}, URL = {http://www.coli.uni-sb.de/~dienes/oravecz_dienes_02.ps.gz}, Abstract = {Many of the methods developed for Western European languages and used widespread to produce annotated language resources cannot readily be applied to Central and Eastern European languages, due to the large number of novel phenomena exhibited in the syntax and morphology of these languages, which these methods have to handle but have not been designed to cope with. The process of morphological tagging when applied to Hungarian data to produce corpora annotated at least at the morphosyntactic level is most indicative of this problem: several of the algorithms (either rule-based or statistical) that have been used very successfully in other domains cannot readily be applied to a language exhibiting such a varied morphology and huge number of wordforms as Hungarian.

In German all permutations of the subject, the indirect, and the direct object do occur. Yet, they are supposed to differ regarding their degree of acceptability. Uszkoreit (1987) proposed a set of rules which aimed at representing such preferences as the product of different factors. This theoretical account leads to a predicted ranking of the possible syntactic forms. In a set of experiments we tested some of these predictions by application of different methods for tapping into the actual processing of the sentences. In particular, the predictions were (a) that sentences are more acceptable if subjects precede objects than vice versa and (b) that sentences are more acceptable if indirect objects precede direct objects than vice versa. Both comprehension and production experiments were carried out. The methods we used included a ranking task, delayed sentence matching, delayed articulation, rapid serial visual presentation and a sentence generation task. The findings yielded a very consistent picture concerning the position of the subject. Sentences were particularly easy to process if the subject was in initial position and particularly hard to process in subject-final constructions. Furthermore, there is somewhat weaker evidence for the assumption that sentences are easier to process if direct objects are preceded by indirect objects. Since these results were obtained by rather different methods they can be regarded as particularly reliable. Moreover, the data did provide evidence for a gradual increase or decrease of acceptability and no evidence for a jump function, sharply separating grammatical from ungrammatical forms. One of the principal aims of this first phase of our investigations which is reported in the present paper was to find experimental methods which consistently differentiate between the various permutations of verb complements as predicted by theoretical assumptions. This aim could be achieved. The next step will be to include pragmatic factors which are supposed to play a significant role in determining the acceptability of the sentences we are studying.}, Year = {1994} } @incollection{ Pechmann:1996:WID, Author = {Pechmann, Thomas and Uszkoreit, Hans and Engelkamp, Johannes and Zerbst, Dieter}, Title = {Wortstellung im Deutschen Mittelfeld}, BookTitle = {Perspektiven der Kognitiven Linguistik}, Editor = {Habel, Christopher and Kanngießer, Siegfried and Rickheit, Gert}, Address = {Oplaten}, Publisher = {Westdeutscher Verlag}, Pages = {257-299}, CoLiURL = {Pechmann:1996:WID.pdf}, URL = {http://www.dfki.de/dfkibib/publications/docs/Pechmann_1994_WOIGMF.pdf}, Year = {1996} } @inproceedings{ Peeters:1989:DDP, Author = {Peeters, Wim J. and Barry, William J.}, Title = {Diphthong Dynamics: Production and Perception in Southern British English}, BookTitle = {European Conference on Speech Communication and Technology (EUROSPEECH '89), September}, Editor = {Tubach, J.

The algorithm is presented as the simplification of the constraints which form the (possibly deep) guards and which are situated at different nodes (or, local computation spaces) in a tree (of arbitrary depth). In this algorithm, each variable may have multiple bindings (representing multiple constraints on the same variable in different nodes). These may be realized by re- and de-installation upon each newly resumed check of the guard in the corresponding node (as done, e.g., in AKL or Oz), or by using look-up tables (with entries indexed by the nodes).

Our starting point is the observation that the same propositional content often can be expressed linguistically by different lexical and grammatical means, for instance, by word order alternatives or by using different lexical categories. These alternatives result from the exploitation of a number of linguistic mechanisms (e.g., focussing, thematization) controlling the foregrounding and backgrounding of different parts of information communicated and differ in the pragmatic effects they achieve. Our interest lies in the textual-pragmatic motivations leading to the choice of a certain textual variant; in particular, we investigate the constraints global discourse structure imposes on sentence-level discourse organization. Proceeding from a stratificational model of the language system, our approach aims at the specification of interstratal constraints expressing the interdependency between higher-level discourse organization and lexico-grammatical realization on sentence level. A possible application area would be text generation where a notorious problem is the gap between global-level text planning and lexico-grammatical expression. The choice of grammatical (sentence) theme in German and its text type and domain dependency is taken as a sample phenomenon to illustrate our methodology.}, Year = {1995} } @incollection{ Ramm:1996:WTF, Author = {Ramm, Wiebke and Villiger, Claudia}, Title = {Wissenschaftliche Textproduktion und Fachdomäne.

The words were also varied systematically in their complexity and in the familiarity of their syllable structure. They combined familiar and unfamiliar sounds with known [CV(son)] and unknown [C(C)VC(C)] syllables. The realisations by the Korean learners were analysed for deviations from the native productions with respect to pause behaviour, articulation rate, the duration of the selected words, and the relative syllable duration within those words. Results show that unfamiliar sounds, syllable structure and Korean syllable-dependent rhythmic patterning combine to interfere with the production of the correct German rhythm. As the length and the syllable complexity of the German target words increases so does the degree of deviation from the native German patterns. Length of exposure to German did not appear to guarantee a closer approximation to the target patterns, but all learners were able to modify their L2-productions in the imitation task.}, Year = {1997} } @techreport{ Riezler:1995:BH, Author = {Riezler, Stefan}, Title = {Binding Without Hierarchies}, Address = {Saarbrücken}, Institution = {Universität des Saarlandes}, Number = {50}, Type = {CLAUS-Report}, Month= {January}, CoLiURL = {Riezler:1995:BH.pdf Riezler:1995:BH.ps}, URL = {ftp://ftp.coli.uni-sb.de/pub/coli/claus/claus50.ps}, Abstract = {The aim of this paper is to show that current HPSG binding theory (and similarly other binding approaches encoding asymmetries explicitly) is inadequate with regard to describing binding variabilities in local binding contexts.

Type expansion is an operation that makes the constraints on a typed feature structure explicit and determines their satisfiability. We describe an efficient expansion algorithm that takes care of recursive type definitions and allows exploration of different expansion strategies through the use of control knowledge. This knowledge is specified in a separate layer, independently of grammatical information. Memoization of the type expansion function drastically reduces the number of unifications. In the second part, nonmonotonic extensions to TDL and the implementation of well-typedness checks are presented. Both are closely related to the type expansion algorithm.

Starting from an informal description of the dynamic semantics in terms of a graph model, we develop step by step on various levels of abstraction a virtual machine for L. We begin with a simple basic model. We then propose several optimizations of this model. Afterwards we keep refining our approach by addressing specific aspects of the implementation of the model.

For this off-line scheduling problem a potentially indefinite, periodic processing has to be mapped onto a single time window of a fixed length. We make this new class of applications amenable to constraint programming. We describe which traditional scheduling and real-time computing techniques led to success and which failed when confronted with a large-scale application of this type. Global constraints were used to reduce memory consumption and to speed up computation. An elaborate heuristic, borrowed from Operations Research, was employed to solve the problem.

The obtained distributed search engines are simple yet offer substantial speedup on standard network computers.}, Year = {2000} } @incollection{ Walde:2001:SGM, Author = {Schulte im Walde, Sabine and Schmid, Helmut and Rooth, Mats and Riezler, Stefan and Prescher, Detlef}, Title = {Statistical Grammar Models and Lexicon Acquisition}, BookTitle = {Linguistic Form and its Computation}, Address = {Stanford}, Publisher = {CSLI Publications}, CoLiURL = {Walde:2001:SGM.pdf}, URL = {http://www.dfki.de/~prescher/papers/bib/2001csli.schulte_im_walde.schmid.rooth.riezler.prescher.pdf}, Year = {2001} } @inproceedings{ Schwenter:2000:ARS, Author = {Schwenter, Scott A. and Vasishth, Shravan}, Title = {Absolute and Relative Scalar Particles in Spanish and Hindi}, BookTitle = {26th Berkeley Linguistics Society Conference (BLS 26), February 18-21}, Address= {University of California, Berkeley, USA}, Pages = {225-233}, CoLiURL = {Schwenter:2000:ARS.pdf}, URL = {ftp://ftp.ling.ohio-state.edu/pub/Students/Vasishth/Published/BLS2000/BLS00paper.pdf}, Year = {2000} } @inproceedings{ Sen:1992:AMS, Author = {Sen, Sandip and Durfee, Edmund H.}, Title = {Automated Meeting Scheduling among Heterogeneous Agents}, BookTitle = {AAAI Workshop on Cooperation among Heterogeneous Intelligent Systems, June}, Address= {San Jose, California, USA}, Year = {1992} } @article{ Shieber:1990:SHD, Author = {Shieber, Stuart M. and van Noord, Gertjan and Pereira, Fernando and Moore, Robert}, Title = {A Semantic-Head-Driven Generation Algorithm for Unification-Based Formalisms}, Journal = {Computational Linguistics}, Volume = {16}, Number = {1}, Pages = {30-42}, Year = {1990} } @techreport{ Siegel:1994:DNA, Author = {Siegel, Melanie}, Title = {Definitheit und Numerus.

They can mark arguments as well as adjuncts, can be functional or have semantic funtions. There is, however, no straightforward matching from particles to functions, as, e.g., ga can mark the subject, the object or an adjunct of a sentence. Particles can cooccur. Verbal arguments that could be identified by particles can be eliminated in the Japanese sentence. And finally, in spoken language particles are often omitted. A proper treatment of particles is thus necessary to make an analysis of Japanese sentences possible. Our treatment is based on an empirical investigation of 800 dialogues.

Polysemy and metonymy are examples for this phenomenon. These meaning shifts of words can be modeled by augmenting the semantic representation of a natural language utterance with the information that is missing to make the shift in meaning explicit. This information can be provided by linguistic or non-linguistic sources or an interaction of both. Recently, Egg (1999) has suggested an account of meaning shifts which exploits underspecification methods to yield a monotonic augmentation process. The main idea is to have semantic construction derive a sufficiently relaxed (i.e. made less specific) semantic representation, so that adding the missing information is simply further specification of this representation. This thesis will examine a treatment of meaning shifts due to systematic polysemy or metonymy within Egg's framework. We will present a syntax/semantics interface which derives appropriately relaxed semantic representations. To account for meaning shifts these representations can be augmented monotonically with additional information. We will point out a potential problem for this approach: making underspecified semantic representations less specific may cause overgeneration. However, as we will show, for our applications relaxation is safe, i.e. there is no danger of overgeneration. The underspecification formalism that we will use throughout this thesis is in the class of tree description languages subsuming dominance constraints. We will distinguish a novel class of subconstraints with a certain structure which powerfully support the type of inferences on dominance and disjointness which we have to make for proving safety of relaxation.}, Year = {1999} } @inproceedings{ Striegnitz:2001:MCC, Author = {Striegnitz, Kristina}, Title = {Model Checking for Contextual Reasoning in NLG}, BookTitle = {Proceedings of Inference in Computational Semantics (ICoS-3), June 18-23}, Editor = {Blackburn, Patrick and Kohlhase, Michael}, Address= {Siena, Italy}, Pages = {101-115}, CoLiURL = {Striegnitz:2001:MCC.pdf Striegnitz:2001:MCC.ps}, URL = {http://www.coli.uni-sb.de/cl/projects/indigen/papers/icos3.ps.gz}, Abstract = {Presupposition triggers, such as e.g. 'the', 'too', 'another', impose constraints on the context they are used in.

That way information contained in the lexicon and the morphological grammar can guide the application of the two-level rules. Moreover, information can be transmitted from the two-level part to the grammar part. This approach allows for a natural description of some nonconcatenative morphological phenomena as well as morphonological phenomena that are restricted to certain word classes in their applicability. The approach is applied to German inflectional and derivational morphology.

However, deep grammatical analysis has played a negligible role in the development of language technology applications. Deep parsers have been lacking efficiently and robustness. Building up coverage has been slow and costly. The few linguistic grammars that truly exhibit large coverage have caused a constant fight with extensive ambiguity. In my talk I will present recent developments that provide new challenges and opportunities for linguistic methods. Increased efficiency of deep parsing and the embedding of a selective deep analysis into a robust shallow regime for information extraction offer ways to employ deep parsing in an environment where it can improve results without ruining robustness. I will argue that such a selective utilization as we have realized it by an integration of HPSG parsing into a hybrid IE system comprised of statistical and FST components, also provides a promising direction for gradual, measurable controlled progress in the development of deep grammars and lexicons.}, Year = {2002} } @inproceedings{ Uszkoreit:1994:DHBa, Author = {Uszkoreit, Hans and Backofen, Rolf and Busemann, Stephan and Diagne, Abdel Kader and Hinkelman, Elizabeth and Kasper, Walter and Kiefer, Bernd and Krieger, Hans-Ulrich and Netter, Klaus and Neumann, Günter and Oepen, Stephan and Spackman, Stephen P.}, Title = {DISCO - An HPSG-Based NLP System and its Application for Appointment Scheduling}, BookTitle = {Proceedings of the 15th International Conference on Computational Linguistics (COLING'94), August 5-9}, Volume = {1}, Address= {Kyoto, Japan}, Pages = {436-440}, CoLiURL = {Uszkoreit:1994:DHBa.pdf Uszkoreit:1994:DHBa.ps}, URL = {ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/coli.ps.Z ftp://ftp.dfki.uni-kl.de/pub/Publications/ResearchReports/1994/RR-94-38.ps.gz ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/coli.dvi.Z ftp://lt-ftp.dfki.uni-sb.de/pub/papers/local/coli.entry}, Abstract = {The natural language system DISCO is described.

More recently, a number of alternatives based on treebank resources (such as Penn-II, Susanne, AP treebank) have been explored. The idea is to automatically “induce” or rather read off (P)CFG grammars from the parse annotated treebank resources and to use the treebank grammars thusobtained in (probabilistic) parsing or as a starting point for further grammar development. The approach is cheap, fast, automatic, large scale, “data driven” and based on real language resources. Treebankgrammars typically involve large sets of lexical tags and non-lexical categories as syntactic informationtends to be encoded in monadic category symbols. They feature flat rules (trees) that can “underspecify” attachment possibilities. Treebank grammars do not in general follow Xbar architectural design principles (this is not to say that treebank grammars do not have design principles). As a consequence, treebank grammars tend to have very large CFG rule bases (e.g. Penn-II > 17,000 CFG rules for about 1 million words of text) with often only minimally differing rules. Even though treebank grammars are large, they are still incomplete, exhibiting unabated rule accession rates. From a grammar engineering point of view, the size of the rule base poses problems for maintainability, extendability and, if a treebank grammar is to be used as a CF-base in a LFG grammar, for functional (feature-structure) annotations. From the point of view of theoretical linguistics, flat treebank trees and treebank grammars extracted from such trees do not express linguistic generalisations. From the perspective of empirical and corpus linguistics, flat trees are well-motivated as they allow underspecification of subtle and often time consuming attachment decisions. Indeed, it is sometimes doubted whether highly general Xbar schemata usefully scale to “real” language. In previous work we developed methodologies for automatic feature-structure annotation of grammars extracted from treebanks. Automatic annotation of “raw” treebank grammars is difficult as annotation rules often need to identify subsequences in the RHSs of flat treebank rules as they explicitly encode head, complement and modifier relations. Xbar-based CFG rules should substantially facilitate automatic feature-structure annotation of grammar rules. In the present paper we conduct a number of experiments to explore a space of possible grammars based on a small fragment of the AP treebank resource. Starting with the original treebank fragment we automatically extract a CFG G. We then apply an automatic structure preserving grammar compaction step which generalises categories in the original treebank fragment and reduces the number of rules extracted, resulting in a generalised treebank fragment and in a compacted grammar Gc. The generalised fragment is then manually corrected to catch missed constituents (and the like) resulting in an automatically extracted, compacted and (effectively manually) corrected grammar Gc;m. Manual correction proceeds in the “spirit” of treebank grammars (we do not introduce Xbar analyses). We then explore how many of the manual correction steps on treebank trees can be achieved automatically. We develop, implement and test an automatic treebank “grooming” methodology which is applied to the generalised treebank fragment to yield a compacted and automatically corrected grammar Gc;a. Grammars Gc;m and Gc;a are very similar to compiled out “flat” LFG-82 style grammars. We explore regular expression based compaction (both manual and automatic) to relate Gc;m to a LFG-82 style grammar design. Finally, we manually recode a subsection of the generalised and manually corrected treebank fragment into “vanilla-flavour” Xbar based trees. From these we extract a compacted, manually corrected, Xbar-based grammar Gc;m;x. We evaluate our grammars and methods using standard labelled bracketing measures and according to how well they perform under automatic feature-structure annotation tasks.}, Year = {2001} } @techreport{ Leusen:1997:RIR, Author = {van Leusen, Noor}, Title = {The Role of Inference in the resolution of corrections}, Address = {Saarbrücken}, Institution = {Universität des Saarlandes}, Number = {93}, Type = {CLAUS-Report}, Month= {December}, Year = {1997} } @techreport{ Noord:1991:HCP, Author = {van Noord, Gertjan}, Title = {Head Corner Parsing}, Address = {Saarbrücken}, Institution = {Universität des Saarlandes}, Number = {15}, Type = {CLAUS-Report}, Month= {December}, Abstract = {I describe a head-driven parser for a class of grammars that handle discontinuous constituency by a richer notion of string combination than ordinary concatenation.

On the one hand it needs to be decided what should be said. This task is delegated to a planning component. Such a component might produce an expression representing the content of the proposed utterance. On the basis of this representation the syntactic generation component produces the actual output sentence(s). Although the distinction between planning and syntactic generation is not uncontroversial, we will nonetheless assume such an architecture here, in order to explain some of the issues that arise in syntactic generation. A (natural language) grammar is a formal device that defines a relation between (natural language) utterances and their corresponding meanings. In practice this usually means that a grammar defines a relation between strings and logical forms. During natural language understanding, the task is to arrive at a logical form that corresponds to the input string. Syntactic generation can be described as the problem to find the corresponding string for an input logical form. We are thus making a distinction between the grammar which defines this relation, and the procedure that computes the relation on the basis of such a grammar. In the current state of the art unification-based (or more general: constraint-based) formalisms are used to express such grammars, e.g., Lexical Functional Grammar (LFG) [Bre82], Head-Driven Phrase-Structure Grammar (HPSG) [PS87] and constraint-based categorial frameworks (cf. [Usz86] and [ZKC87]). Almost all modern linguistic theories assume that a natural language grammar not only describes the correct sentences of a language, but that such a grammar also describes the corresponding semantic structures of the grammatical sentences. Given that a grammar specifies the relation between phonology and semantics it seems obvious that the generator is supposed to use this specification. For example, Generalized Phrase Structure Grammars (GPSG) [GKPS85] provide a detailed description of the semantic interpretation of the sentences licensed by the grammar. Thus one might assume that a generator based on GPSG constructs a sentence for a given semantic structure, according to the semantic interpretation rules of GPSG. Alternatively, [Bus90] presents a generator, based on GPSG, which does not take as its input a logical form, but rather some kind of control expression which merely instructs the grammatical component which rules of the grammar to apply. Similarly, in the conception of [GP90], a generator is provided with some kind of deep structure which can be interpreted as a control expression instructing the grammar which rules to apply. These approaches to the generation problem clearly solve some of the problems encountered in generation---simply by pushing the problem into the conceptual component (i.e., the planning component). In this overview we restrict the attention to the more ambitious approach sketched above. The success of the currently developed constraint-based theories is due to the fact that they are purely declarative. Hence, it is an interesting objective---theoretically and practically---to use one and the same grammar for natural language understanding and generation. In fact the potential for reversibility was a primary motivation for the introduction of Martin Kay’s Functional Unification Grammar (FUG). In recent years interest in such a reversible architecture has led to a number of publications.}, Year = {1987} } @article{ Roy:1997:MOD, Author = {Van Roy, Peter and Haridi, Seif and Brand, Per and Smolka, Gert and Mehl, Michael and Scheidhauer, Ralf}, Title = {Mobile Objects in Distributed Oz}, Journal = {ACM Transactions on Programming Languages and Systems}, Volume = {19}, Number = {5}, Pages = {804-851}, CoLiURL = {Roy:1997:MOD.pdf Roy:1997:MOD.ps}, URL = {ftp://ftp.ps.uni-sb.de/pub/papers/ProgrammingSysLab/TOPLAS97.ps.gz}, Abstract = {Some of the most difficult questions to answer when designing a distributed application are related to mobility: what information to transfer between sites and when and how to transfer it. Network-transparent distribution, the property that a program's behavior is independent of how it is partitioned among sites, does not directly address these questions. Therefore we propose to extend all language entities with a network behavior that enables efficient distributed programming by giving the programmer a simple and predictable control over network communication patterns. In particular, we show how to give objects an arbitrary mobility behavior that is independent of the object's definition. In this way, the syntax and semantics of objects are the same regardless of whether they are used as stationary servers, mobile agents, or simply as caches. These ideas have been implemented in Distributed Oz, a concurrent object-oriented language that is state aware and has data flow synchronization. We prove that the implementation of objects in Distributed Oz is network transparent. To satisfy the predictability condition, the implementation avoids forwarding chains through intermediate sites.

This analysis is integrated into a framework that concerns a uniform treatment of semantically underspecified information and parallelism phenomena in discourse. The analysis put forward in this thesis gives correct predictions about the strict and sloppy readings of a series of problematic cases in the literature. It does not suffer from undergeneration or overgeneration problems. We use linking relations between anaphoric pronouns and their antecedents and claim that the interaction between linking relations and the parallelism requirement in VPE results in strict and sloppy readings.

I will offer an analysis that preserves Pustejovsky's intuition but avoids these shortcomings.
