摘要

Event knowledge is playing an increasingly important role in a number of areas. The purpose of this paper is to automatically extract event knowledge from text. Based on the event model, this paper presents the definition of event, and builds the framework of dynamic event to represent the instantiation knowledge of events and the framework of static event to describe the general knowledge of events. It discusses the relationship between the attribute values of dynamic events and that of corresponding static event, and establishes the concept hierarchy trees to express their relations. Based on these analyses, an algorithm for automatically extracting event knowledge from text is presented. The result of the final experiment demonstrates that the proposed algorithm is feasible and effective.
