Chinese Argument Extraction Based on Trigger Mapping

摘要：

　　Unlike English, Chinese sentences do not have a strict syntactic structure and ellipsis is a common phenomenon, which weaken the effective ness of syntactic structure in argument extraction.In Chinese event extraction, lots of arguments cannot be extracted from the sentence successfully, because of the loose connection between the nominal trigger and its arguments.This paper brings forward a novel argument extraction approach based on trigger mapping.It maps the nominal trigger to its predicate and uses it as a key to ex tract syntactic features for classification.Experimental results on the ACE 2005 Chinese Corpus show that, in terms of Fl-measure in argument identification and role determination, our approach achieves an obvious improvement.
