Unificational Combinatory Categorial Grammar: Combining Information Structure and Discourse Representations

摘要

In this paper we present a grammar formalism that combines the insights from Combinatory Categorial Grammar with feature structure unification. We show how information structure can be incorporated with syntactic and semantic representations in a principled way. We focus on the way theme, rheme, and focus are integrated in the compositional semantics, using Discourse Representation Theory as first-order semantic theory. UCCG can be used for parsing and generating prosodically annotated text, and therefore has the potential to advance spoken dialogue systems.
