Large-scale phrase structure treebank and dependency structure treebank are developed and interconverted for the purpose of syntactic analysis on true corpus. The head percolation table is constructed on modern Chinese dependency grammar by discussing the relationship between phrase structure and dependency structure based on Penn Chinese Treebank (CTB),and CTB from phrase structure is converted to dependency structure treebank using the head percolation table. 200 sentences are chosen from CTB randomly to evaluate the conversion performance. Precision of the conversion has attained 99.50%. The achieved dependency structure treebank can be used to analyze Chinese dependency relation.
