In this paper we describe a meta level representation used for mapping natural language input into propositions of an expert system. This representation is based on verb classes that are structured hierarchically, with more general information encoded in the top level nodes and more specific information in the lower level nodes. Because of its structure, the representation is able to provide a detailed classification of the propositions, supplying a basis for defming semantics. It allows the system to answer questions about relationships between propositions without inferencing, as well as to answer questions the expert system could not previously handle.
