Issue Date: | 2009 | Citation: | Lin, Z.,Kan, M.-Y.,Ng, H.T. (2009). Recognizing implicit discourse relations in the Penn Discourse Treebank. EMNLP 2009 - Proceedings of the 2009 Conference on Empirical Methods in Natural Language Processing: A Meeting of SIGDAT, a Special Interest Group of ACL, Held in Conjunction with ACL-IJCNLP 2009 : 343-351. ScholarBank@NUS Repository. | Abstract: | We present an implicit discourse relation classifier in the Penn Discourse Treebank (PDTB). Our classifier considers the context of the two arguments, word pair information, as well as the arguments' internal constituent and dependency parses. Our results on the PDTB yields a significant 14.1% improvement over the baseline. In our error analysis, we discuss four challenges in recognizing implicit relations in the PDTB. © 2009 ACL and AFNLP. | Source Title: | EMNLP 2009 - Proceedings of the 2009 Conference on Empirical Methods in Natural Language Processing: A Meeting of SIGDAT, a Special Interest Group of ACL, Held in Conjunction with ACL-IJCNLP 2009 | URI: | http://scholarbank.nus.edu.sg/handle/10635/41325 |
