The current approaches to Semantic Role Labeling (SRL) usually perform role clas- sification for each predicate separately and the interaction among individual predi- cate?s role labeling is ignored if there is more than one predicate in a sentence. In this paper, we prove that different predi- cates in a sentence could help each other during SRL. In multi-predicate role label- ing, there are mainly two key points: argu- ment identification and role labeling of the arguments shared by multiple predicates. To address these issues, in the stage of argument identification, we propose nov- el predicate-related features which help re- move many argument identification errors; in the stage of argument classification, we adopt a discriminative reranking approach to perform role classification of ...
