As a consequence of the rise of amount of lexical information put in linguistic theories, the so-called head-driven processing, arose recently as attempts to incorporate the use of lexical information in computational applications as an explicit computational behavior. Instead of adding special mechanisms (such as the use of "head" feature structure) to our formalism, we explore the view that syntactical rules are not separated from lexical items. In our approach, each elementary structure is systematically associated with a lexical item. These structures specify extended domains of locality (as compared to Context-Free Grammars) over which constraints can be stated. The "grammar" consists of a lexicon where each lexical item is associated with a finite number of structures for which that item is the anchor. There are "rules" which tell us how these structures are composed. A grammar of this form will be said to be lexicalized. Context-free grammars are not in general in a lexicalized form. We show how the process of lexicalizing context-free grammars yields lexicalized tree-adjoining grammars which are naturally lexicalized. We illustrate the main structures found in a lexicalized TAG for English. As first shown by Kroch and Joshi (1985), the properties of TAGs permit us to encapsulate diverse syntactic phenomena in a very natural way. TAG's extended domain of locality and its factoring of recursion from local dependencies enable us to localize many syntactic dependencies (such as filler-gap) as well as semantic dependencies (such as predicate-arguments). After discussing lexicalization, we show how lexicalized grammars suggest a natural two-step parsing strategy. We review the main types of parsing algorithms for TAGs (DCG-style, CKY-style, Earley-style and LR-style) and summarize the effect of the two-step parsing strategy on these algorithms. Finally, we mention recent work in collaboration with Stuart Shieber on synchronous tree-adjoining grammars which, by characterizing correspondences between languages, enable us to use TAG beyond the confines of syntax, for example for the task of semantic interpretation, generation and machine translation. ******************************************************* Suggestions for AI Seminar speakers are always welcome.

The purpose of the workshop is to assess the state of the art and provide a snapshot of ongoing research in Case-Based Reasoning. The workshop is intended to bring active researchers together to review the latest research results in this field, to keep the government research community abreast of current technology, and to discuss the future of the case-based paradigm for a new generation of knowledge-based systems. The 1989 workshop was centered around a set of issue-oriented panels that discussed fundamental problems of Case-Based Reasoning, including case representation, indexing, similarity assessment, and case adaptation. The goal of this year's workshop is to discuss the progress of researchers towards solving these problems in the context of Case-Based Reasoning systems. Consequently, the program committee will prefer papers that discuss implemented systems over those that discuss unimplemented ideas. Papers that are concrete and concise will be preferred over those that are philosophical and/or abstract. Since AI research is largely an experimental science, it is anticipated that these papers will describe experiments performed and the measures applied to evaluate the experimental results. Papers that discuss specific applications where integration and/or scalability issues were solved in novel ways and program demonstrations are also encouraged. Researchers interested in demonstrating programs should contact Ray Bareiss to arrange for the needed computer equipment. A second goal of the workshop will be to provide challenges for future research by encouraging interaction between researchers and potential beneficiaries of their research, such as industrial designers, instructional designers, and builders of large software systems. Researchers who would like to present at the workshop are asked to submit five copies of their papers to: CBR91 Workshop c/o Ray Bareiss Institute for the Learning Sciences Northwestern University 1890 Maple Avenue Evanston, IL 60201 Submitted papers should be camera-ready, not exceeding twelve single-spaced pages including figures and bibliography. Formatting instructions will be sent via surface mail along with a hard copy of this announcement. It is the intention of the program committee to accept papers for publication as submitted, i.e., without revision. People who wish to attend without presenting should submit a brief statement of interest. The submission deadline is January 18, 1991; notification of acceptance will be made by February 28, 1991. As with other DARPA/ISTO sponsored workshops, a full proceedings of the workshop will be made available to those who attend.

It is useful, however, to think of text as being composed of higher level objects than bytes, and to be able to write computer programs that operate on these objects, as well as on collections of objects. The purpose of the Textual Object Management System (TOMS) is to implement an abstraction of text as a structure populated by such objects. In this talk I discuss the abstraction presented by the TOMS, from the point of view of both a client and a textual database designer. - ------------------------------- End of CILS Calendar ------------------------------ To: nl-kr@cs.rpi.edu Date: Tue, 20 Nov 90 18:11:35 -0500 >From: mike@park.bu.edu Subject: NN conference [ I include this only because there is a section on connectionist NLP down there in day 4.
