Abstract

Abstract: This paper studies the extraction of text-oriented event information, establishes an event information extraction system. This system filters original corpus contain keywords firstly, obtains initial patterns using the method combined with hierarchical clustering (HCL) and the algorithm of longest common subsequence secondly, and then obtains final patterns contain keywords. Using these patterns information can be extracted and elements of event can be obtained finally.

Key words: information extraction, event information extraction, pattern
