Abstract

This paper borrows the idea from the linguistic theories of lexicalism and makes use of event structure to explore how to understand the statement query, so as to eliminate ambiguity and refine the query. It proposes a new query expansion method based on event structure which helps to improve query expansion by combining with the Knowledge based Query Expansion Method. First, use Event Structure based Query Expansion Agent (ESQEA) to identify queries conforming to verbs’ argument structures, and then realize the query refinement according to the knowledge structure. The simulation result shows that for the same recall, the precision ratio is improved by the new approach.
