Though here are been many different approaches to the representation and processing of spatial expressions, most existing computational treatments have been restricted to particularly narrow problem domains, usually specific spatial contexts determined by overall system goals. To date, AI research in this field has rarely taken advantage of studies of language and spatial cognition carried out by the cognitive science community. One of the intentions of this workshop is to bring together researchers from both disciplines in the belief that artificial intelligence has much to gain from an appreciation of cognitive theories. The workshop will consist of formal presentations, prepared commentaries on presenations and two ``taking issue'' discussions sessions (on ''Function'' and ``Shape'') led our invited speakers.

crl.nmsu.edu>SIGLEX 96 -- CALL for PARTICIPATION ACL'96 Workshop on the BREADTH and DEPTH of SEMANTIC LEXICONS June 28, 1996 Santa Cruz, California, USA. FOCUS OF THE WORKSHOP - ------------------- Building semantic lexicons is a very time consuming task. Efficient large-scale acquisition and representation of lexical knowledge will be greatly aided by capturing regularities in the lexicon. Two main issues present themselves: a) treatment of lexical ambiguity and b) lexical rules as a conceptual tool for controlled proliferation of entries. Whereas the former has been regarded as a topical issue for quite some time, the latter is only now receiving its due attention. This workshop will concentrate on lexical rules as a regulator of breadth and depth of the lexicons. Lexical rules are known under a variety of names, e.g., Leech's (1991) "semantic transfer rules," "lexical inference rules" of Ostler and Atkins (1991) and others. They are also addressed in the framework of such theories as the generative lexicon of Pustejovsky (1995). Such linguistic frameworks as LFG and HPSG have also used the concept, albeit in a different sense and for a different purpose. At the same time, theoretical accounts of the use of lexical rules (such as, for instance, preemption or blocking) are rather too general and underspecified to support actual processing. The workshop will stress issues connected with the practical application of lexical rules: when to apply the rules, how the rules influence system design, how to reexamine and adjust the theoretically posited rules in view of practical needs and evidence. Another central issue for the workshop will be large-scale acquisition of computational-semantic lexicons. We are mainly interested in examining the following trade-offs: the coverage vs.the depth of existing semantic lexicons vs. the effort involved in building them. The workshop is intended for researchers in computational linguistics, artificial intelligence, psycholinguistics or other fields who have been working in lexical semantics and large-scale lexical knowledge acquisition. Some (though not necessarily all) specific questions suggested for discussion include: 1) What are the different types of lexical rules which should be considered in the building of computational lexicons (inflectional and derivational morphology, verbal diatheses, regular word-sense shifts, other) 2) When should the rules be applied (run-time, load-time, acquisition, other) 3) How to evaluate the cost-efficiency of the acquisition effort against the utility of the resulting lexicons. How could we characterize an NLP system along the dimensions of size, corpus coverage, and depth. 4) Analyses of appropriate types of inheritance for different lexical rules. 5) The use of lexical underspecification (and contextual word-use grounding) as a partial alternative to lexical rules. PROGRAM - ----- The meeting is scheduled from 8:30am to 6pm. The papers will be organised around topics followed by discussions. A summary general discussion will be scheduled at the end of the day. Attendees are required to register for the main ACL-96 conference.
