About me
Welcome to my website.
I am a PhD student within the International Research Training Group (IRTG) Language Technology and Cognitive Systems at Saarland University. I am interested in dialogue, spoken dialogue systems and computer assisted language learning (CALL). My supervisor is Manfred Pinkal and I work together with Magdalena Wolska.
Before that I worked with robots in the CoSy project at DFKI Language Technology Lab and did my Diploma thesis under supervision of Geert-Jan Kruijff and Hans Uszkoreit.

German subordinate clause word order in dialogue-based CALL

We present a dialogue system for exercising the
German subordinate clause word order. The pedagogical method-
ology we adopt is based on focused tasks: the targeted linguistic
structure is embedded in a naturalistic scenario, "Making ap-
pointments", in which the structure can be plausibly elicited. We
report on the system we built and an experimental methodology
which we use in order to investigate whether the computer-based
conversational focused task we designed promotes acquisition of
the form. Our goal is two-fold: First, learners should improve
their overall communicative skills in the task scenario and,
second, they should improve their mastery of the structure. In
this paper, we present a methodology for evaluating learnersâ
progress on the latter.

We report on a pilot experiment conducted in order to investigate
whether computer-based conversational focused tasks promote
acquisition of forms. The structure we targeted was the
German dative case in prepositional phrases. The goal of the
task we designed was two-fold: First, learners should improve
their overall communicative skills in the scenario and, second,
expand their mastery of the target structure. In this paper, we
present an evaluation of learners' progress on the latter.

Role-plays for CALL: System Architecture and Resources.

We present a system architecture for roleplay-like dialogue exercises for computerassisted
language learning (CALL). Our ultimate goal is to (i) provide learners with
flexible dialogue exercises which facilitate practising interactive skills in a variety of
typical communicative scenarios, and (ii) provide teachers and CALL content developers
with an environment which would allow them to create and maintain resources
needed for such exercises in an easy way. The modularity of our dialogue exercise architecture
is motivated by the envisioned distribution of labour in resources authoring
between language experts (linguistic resources) and knowledge engineering experts
(domain models for the dialogue scenarios).

Service robots dealing with indirect speech acts.

Successful interaction between a service robot and its human users
depends on the robot's ability to understand not only direct commands,
but also more indirect ways for a human to express what she would like
the robot to do. Such indirect ways are pervasive in human-human
interaction; enabling the robot to understand them can make
human-robot interaction more human-friendly. This paper presents a
model for a robot that pursues its serving duties by trying to
interpret indirect ways of expressing requests to execute certain
actions. In case of uncertainty about the proper interpretation the
robot can ask for clarification and adapt its interpretation for
future interactions.

Dispositions for Sociable Robots.Sabrina Wilske.

One of the great challenges in Artificial Intelligence is to build sociable robots that humans can easily and intuitively interact with.
This requires to examine the mechanisms and capabilities that underly social
interaction and to provide robots with the necessary skills to take part in those
social processes.
A central issue is adaptivity -- the robot must be able to change its behavior
based on its experience. This thesis proposes the acquisition of
dispositions -- behavioral tendencies or preferences -- as a general
adaptive mechanism to enable social behavior.
The thesis develops and implements a model that enables dispositions to determine
behavior in the physical and social environment. A robot acquires dispositions
for actions aimed at
certain kinds of objects based on verbal feedback of a
human and the success of those actions.
Dispositions are further applied to communicative actions:
based on linguistic knowledge and depending on the reactions of communication partners, the robot learns (a) how to interpret indirect speech acts and (b) how to engage others to help it in pursuing its goals.
By giving such exemplary applications of dispositional mechanisms the thesis
shows how they can be employed to promote social behavior.

My interest for robots was ignited by a seminar in 2004 during which we created talking robots with Lego bricks.
Here's what came out of it.
