Semantic Role Labeling Based on Dependency Relationship
Guodong Zhou · Jisuanji gongcheng · 2009
Aiming at the bottlenecks of syntactic tree-based Semantic Role Labeling(SRL),this paper explores dependency relationship-based semantic role labeling.By properly integrating dependency parsing,predicate identification,feature extraction,semantic role identification and semantic role classification,this system achieves the F1 measure of 80.94% on the WSJ portion of the CoNLL2008 SRL Shared Task,using automatic dependency parsing.Experimental results show that it is better than the F1 measure of syntactic tree-based semantic role labeling apparently.
