Computing Perspective in Dialogue
Hausser Roland · Frontiers in artificial intelligence and applications · 2012
A computational reconstruction of communication in dialogue requires not only an analysis of language expressions, but of utterances. In DBS, an utterance is defined as (i) a propositional content and (ii) a cluster of pointers called STAR. The STAR serves to anchor a content to the interpretation's parameter values of Space, Time, Agent, and Recipient. The STAR also provides the referents for a certain kind of sign in natural language, namely the indexical.
