This paper describes aUDt ("Resolving Underspecification with Discourse Information"), a dialogue system component which computes automatically some aspects of the content of scheduling dialogues, particularly the intended denoration of the temporal expressions, the speech acts performed and the underlying goals. aUDt has a number of nice features: it is a principled approximation of a logically precise and linguistically motivated framework for representing semantics and implicatures; it has a particularly simple architecture; and it records how reasoning with a combination of goals, semantics and speech acts serves to resolve underspecification that's generated by the grammar.
