Abstract:

An integrated method based on decision tree for Chinese pronominal coreference is proposed. The basic idea is to some extent that filtering out the negative examples based on rules and could compensate the drawback of decision tree that ignoring the relationship between attributes. The performance of the proposed method is tested on Chinese Treebank. In our experiments, the attributes and coreferences are manually labeled, and then the rule patterns are utilized to feature vectors following the decision tree of C4.5 algorithm. The success rate is 82.59%, in which the rate of personal pronouns and demonstrative pronouns are 87.60% and 75.21% respectively.

Key words: natural language understanding, coreference resolution, Chinese pronoun, decision tree, filter rules
