Narrative Schema as World Knowledge for Coreference Resolution
J. O. Irwin, Mamoru Komachi, Yūji Matsumoto · 2011
In this paper we describe the system with which we participated in the CoNLL-2011 Shared Task on modelling coreference. Our system is based on a cluster-ranking model proposed by Rahman and Ng (2009), with novel semantic features based on recent research on narrative event schema (Chambers and Jurafsky, 2009). We demonstrate some improvements over the baseline when using schema information, although the effect varied between the metrics used. We also explore the impact of various features on our system’s performance. 1
