This paper presents an effective framework for Chinese syntactic parsing, which includes two parts. The first one is a parsing framework, which is based on an improved bottom-up chart parsing algorithm, and integrates the idea of the beam search strategy of N best algorithm and heuristic function of A* algorithm for pruning, then get multiple parsing trees. The second is a novel evaluation model, which integrates contextual and partial lexical information into traditional PCFG model and defines a new score function. Using this model, the tree with the highest score is found out as the best parsing tree. Finally, the contrasting experiment results are given. Keywords—syntactic parsing, PCFG, pruning, evaluation model.
