Abstract:

We describe a theoretical investigation into the semantic space described by our interlingua IL, which currently has 191 main verb classes divided into 434 subclasses. represented by 237 distinct Lexical Conceptual Structures LCSs. Using the model of aspect in Olsen 1994b, 1997a monotonic aspectual composition we have identified 71 aspectually basic subclasses that are associated with one or more of 68 aspectually non-basic classes via some lexical type-shifting rule Bresnan 1982, Pinker 1984, Levin and Rappaport Hovav 1995. This allows us to refine the IL and address certain computational and theoretical issues at the same time. From a linguistic viewpoint, the expected benefits include a refinement of the aspectual model in Olsen 1994b, 1997a which provides necessary but not sufficient conditions for aspectual composition, and a refinement of the verb classifications in Levin 1993 we also expect our approach to eventually produce a systematic definition in terms of LCSs and compositional operations of the precise meaning components responsible for Levins classification. Computationally, the lexicon is made more compact.
