Abstract：This paper explores semantic role classification in Chinese language via tree kernel methods, focusing on how to effectively capture the inherent structured knowledge in a parse tree. It extends the minimum syntactic structure and explores three syntactic structures with respect to the characteristics of semantic role classification. It also explores composite kernel to integrate feature-based methods and kernel-based methods. Evaluation on the Chinese PropBank shows that the tree kernel-based semantic role classification achieves a performance of 91.79% in accuracy. Moreover, our tree kernel method shows complementary to the feature-based methods and further boosts the performance to 94.28% in accuracy, better than the state-of-the-art. Key wordssemantic role labeling; semantic role classification; tree kernel
