Research on tree kernel for Chinese pronominal coreference resolution
Guodong Zhou · Computer Engineering and Applications Journal · 2010
Coreference resolution plays an important role in natural language processing.Research on tree kernel function in recent years has put forward new means for coreference resolution.This paper proposes a tree kernel-based approach to anaphora resolution of pronoun in Chinese.Convolve kernel of SVM is used to obtain structured information.Then this paper combines syntax tree as a feature with other base features.Evaluation on the ACE2005 NWIRE shows that tree kernel can much improve the performance,especially achieving F-measure of 75.8%.
