Rule-based Identification of Chinese zero Anaphora
基于规则的中文零指代项识别研究

A rule-based approach for Chinese zero anaphor detection was proposed. Given a parse tree, the smallest IP sub-tree covering the current predicate was captured. Based on this IP sub-tree, some rules were proposed for detecting whether a Chinese zero anaphor exists. I}his paper also systematically evaluated the rulcbased method on OntoNotescorpus. Using golden parse tree, our method achieves 82. 45 in F-measure. And the F-measure is 63. 84 using automatic parser. The experiment results show that our method is very effective on Chinese zero anaphor detection.
