Title The Lexical Component Of Natural Language Processing
Venue Annual Meeting of the Association of Computational Linguistics
Session Main Conference
Year 1999

Computational linguistics is generally considered to be the branch of engineering that uses computers to do useful things with linguistic signals, but it can also be viewed as an extended test of computational theories of human cognition; it is this latter perspective that psychol- ogists find most interesting. Language provides a critical test for the hypothesis that physical symbol systems are adequate to perform all human cognitive functions. As yet, no adequate system for natural language processing has approached human levels of performance. Of the various problems that natural language processing has re- vealed, polysemy is probably the most frustrating. People deal with polysemy so easily that potential abiguities are overlooked, whereas computers must work hard to do far less well....
