In semantic role labeling, it is required that the semantic role of a verb should be consistent in different sentences. We analyzed the semantic distribution of agents in the semantic role labeling corpus. It is revealed that 85 verbs can't meet the requirement of consistency, which may be accounted by their property of causative verbs instead of volitive verbs. This strategy can be extended to other inconsistency issues in semantic role labeling. %U http://jcip.cipsc.org.cn/EN/abstract/article_2692.shtml
