For example, Yang et al (2005) proposed a template-based statistical approach to compute the semantic compatibility between a pronominal anaphor and an antecedent candidate, and Yang and Su (2007) explored semantic relatedness information from automatically discovered patterns, while Ng (2007) automatically induced semantic class knowledge from a treebank and explored its application in coreference resolution.
this paper focuses on the centering theory (Sidner,1981;Grosz et al.,1995;Tetreault,2001), which reveals the significant impact of the local focus on referring expressions in that the antecedent of a referring expression usually depends on the center of attention throughout the local discourse segment (Mitkov,1998).
