Abstract：Discourse relation analysis is a task of natural language understanding which aimed at analyzing and disposing the semantic relation and rhetorical structure of discourse. Implicit discourse relation analysis is an important subtask of automatically detectind senses of semantic relation between arguments in the absence of direct cues. Currently, the performance of implicit discourse relation analysis is low and state-of-art accuracy can only reach 40%. The major cause of this situation is that the existing methods did not analyze arguments in the semantic frame, limited only to the local features and correlation analysis of arguments. This paper proposes a method of implicit discourse relation inference based on frame semantic. This method automatic recognised semantic frame of arguments through FrameNet and related identification technology. On this basis, we indentify the semantic relation of arguments by the distribution probability of frame semantic relation in large-scale text data. The experimental results show that, only using the first level of frame semantic can improve the detection performance of implicit discourse relation up to 5.14%; meanwhile, this method can make the accuracy rate increased by 10.68% in the case of considering the balance of relation categories.
