      ABSTRACT = {This issue of Natural Language Engineering journal reports on recent achievements in the domain of hpsg-based parsing. Research groups at Saarbrücken, CSLI Stanford and the University of Tokyo have worked on grammar development and processing systems that allow the use of hpsg-based processing in practical application contexts. Much of the research reported here has been collaborative, and all of the work shares a commitment to producing comparable results on wide-coverage grammars with substantial test suites. The focus of this special issue is deliberately narrow, to allow detailed technical reports on the results obtained among the collaborating groups. Thus, the volume cannot aim at providing a complete survey on the current state of the field. This introduction summarizes the research background for the work reported in the issue, and puts the major new approaches and results into perspective. Relationships to similar efforts pursued elsewhere are included, along with a brief summary of the research and development efforts reflected in the volume, the joint reference grammar, and the common sets of reference data.},

      ABSTRACT = {We present a context-free approximation of unification-based grammars, such as HPSG or PATR-II. The theoretical underpinning is established through a least fixpoint construction over a certain monotonic function. In order to reach a finite fixpoint, the concrete implementation can be parameterized in several ways, either by specifying a finite iteration depth, by using different restrictors, or by making the symbols of the CFG more complex adding annotations à la GPSG. We also present several methods that speed up the approximation process and help to limit the size of the resulting CF grammar.}

      ABSTRACT = {Following high hopes and subsequent disillusionment in the late 1980s, the past decade of work in language engineering has seen a dramatic increase in the power and sophistication of statistical approaches to natural language processing, along with a growing recognition that these methods alone cannot meet the full range of demands for applications of NLP. While statistical methods, often described as 'shallow' processing techniques, can bring real advantages in robustness and efficiency, they do not provide the precise, reliable representations of meaning which more conventional symbolic grammars can supply for natural language. A consistent, fine-grained mapping between form and meaning is of critical importance in some NLP applications, including machine translation, speech prosthesis, and automated email response. Recent advances in grammar development and processing implementations offer hope of meeting these demands for precision. This volume provides an update on the state of the art in the development and application of broad-coverage declarative grammars built on sound linguistic foundations -- the 'deep' processing paradigm -- and presents several aspects of an international research effort to produce comprehensive, re-usable grammars and efficient technology for parsing and generating with such grammars.}
