Abstract

We introduce a uniform context mechanism which is able to adequately represent and manage different forms of ambiguities as they occur in the course of text understanding. Different lexical, syntactic and semantic interpretations are clearly separated by assigning each alternative a single context space for local reasoning. The mechanism we propose directly supports the task of disambiguation at all levels of text analysis, since it also incorporates constraints from the discourse context, as text understanding proceeds.
