Abstract
We present a class-based approach to building a verb lexicon that makes explicit the close association between syntax and semantics for Levin classes. We have used Lexicalized Tree Adjoining Grammars to capture the syntax associated with each verb class and have augmented the trees to include selectional restrictions. In addition, semantic predicates are associated with each tree, which allow for a compositional interpretation. 1 Introduction The difficulty of achieving adequate hand-crafted semantic representations has limited the field of natural language processing to applications that can be contained within well-defined sub-domains. Despite many different lexicon development approaches (Mel'cuk, 1988; Copestake and Sanfilippo, 1993; Lowe et al., 1997), the field has yet to develop a clear consensus on guidelines for a computational lexicon. One of the most controversial areas in building such a lexicon is polysemy: how senses can be computationally distinguished and characterize...
