Breadth and Depth of Semantic Lexicons - Notes on the Workshop
Evelyne Viegas · 1996
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 as a regulator of breadth and depth of the lexicons. Lexical are known under a variety of names, e.g., Leech's (1981) transfer lexical implication 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 (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 rules: when to apply the rules, how the influence system design, how to reexamine and adjust the theoretically posited in view of practical needs and evidence. Another central issue for the workshop will be large-scale acquisition of computational-semantic lexicons for practical applications. 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.
