Abstract: This paper introduced a learning approach of Tree Kernel-based Zero Pronouns Recognition, and presented a system based-upon this approach. In order to get the syntax structure tree, which includes the zero pronoun, it marks the sentences of the CTB manually, and constructs a basccorpus.Then, it proposed three different policies to get syntax structure tree, which can be trained by SVM as a feature. At last, it also presented a baseline system based on rules, with which we can compares. Experimental results show that the recognition rate of the approach based on tree kernel is better than the one of the System based on rules.
