| Abstract | . Ambiguity is one of the most difficult problems in natural language processing. We present a dynamic semantics which gives a formal account of the behavior of ambiguous expressions occurring in a sequence of sentences. Ambiguous sentences are represented in an underspecified way and the update potential of underspecified representations is defined. Updating information states with underspecified semantic representations is interleaved with partial disambiguation, helping to avoid the problem of state explosion. In general, it is considered how ambiguity survives throughout a discourse and how contextual information can restrict ambiguity. 1 Introduction Natural language expressions can be highly ambiguous, and this ambiguity may have various faces. Well-known phenomena include lexical and syntactic ambiguities. In this paper we focus on constructing a discourse semantic for quantificational ambiguities and ambiguities evolving in pronoun resolution, as exemplified in (16.1.... |
