Abstract

This thesis report investigates a central problem to natural language processing, namely the problem of semantic ambiguity. The type of semantic ambiguities that are considered are those that are generally resolved by speakers of a given language by relying on common knowledge. Typical of this is the problem of pronoun resolution. In this report we investigate the thesis that the semantic theory of Richard Montague can be extended to accommodate the use of world knowledge. We propose an extension to Montague's notion of contexts of use, and to the meaning representation. Meanings are represented as complex structures containing several features including the denotation. The method uses these structures to build contexts, and discourse structures that are then used in the dialogue to resolve certain types of ambiguities.
