Coreference Resolution Based on Center Theory
Peide Qian · 2009
We systematically explored the use of semantic roles in coreference resolution.Here,the semantic roles were automatically determined using a state-of-the-art SRL system,ASSERT,and integrated into the resolution by combining them with pronoun categories.In particular,this paper employed the semantic roles information based on center theory.Experimental results on the ACE 2003 corpus show that our method can outperform the baseline system by 2.2% in F-measure.Especially for pronoun,the experiments show that the refine system using semantic roles information can significantly boost the performance of the baseline for pronoun resolution.
