摘要
NEXUS is a computational system which uses a dictionary of 100 to 150 event/state concepts to construct representations of narrative text. Associated with each event/state concept are its deep case relations and their default values. Concepts in the dictionary are related by one of seven event/state concept coherence relations. Relationships between concepts include a list of constraints on the matching of case arguments between the two concepts. NEXUS has been successfully applied to eight paragraph-length samples of text. The resulting discourse representations have been used succesfully to answer questions and compute summaries for these texts.
