Abstract

The study of the temporal structure of events in natural language is of prime importance in linguistics. Though there has been recent progress on formal theories of events, these theories do not address certain syntactic and semantic properties peculiar to languages such as Hindi. This paper concentrates on properties related to perfectivity. It motivates a small number of semantic features for events and their objects, such as whether an object exists independently of an event, whether it is totally affected by the event, and so on. It then formalizes these features. It also shows how they can be formalized in an algebraic framework and applied in a categorial grammar to derive the properties of verbal and nominal predicates. The result is an integration of descriptive semantics with algebraic theories of objects and events
