The traditional framework ['or ambiguity res- olution employs only 'static' knowledge, ex- pressed generally as selectional restrictions or domain specific constraints, and makes uo use of any specific knowledge manipulation mech- anisms apart from the simple ability to match valences of structurally related words. In con- traust, this paper suggests how a theory of lex- ical semantics making use of a knowledge rep- resentation framework offers a richer, more ex- pressive vocabulary for lexical information. In particular, by performing specialized inference over the ways in which aspects of knowledge structures of words in context c~Ln be composed, mutually compatible and contextully relevant lexieal components of words and phrases are highlighted. In the view presented here, lexi- cal amb...
