摘要: We present an implicit discourse relation classifier in the Penn Discourse Treebank (PDTB). Our considers context of two arguments, word pair information, as well arguments' internal constituent and dependency parses. results on PDTB yields a significant 14.1% improvement over baseline. In our error analysis, we discuss four challenges recognizing relations PDTB.
