Abstract

This paper presents a plan-based model of dialogue that combines world, linguistic, and contextual knowledge in order to recognize complex communicative actions such as expressing doubt. Linguistic knowledge suggests certain discourse acts, a speaker's beliefs, and the strength of those beliefs; contextual knowledge suggests the most coherent continuation of the dialogue; and world knowledge provides evidence that the applicability conditions hold for those discourse acts that capture the relationship of the current utterance to the discourse as a whole.
