A Simplified Chinese Parser with Factored Model

This paper presents our work for participation in the 2012 CIPS-ParsEval shared task of Simplified Chinese parsing. We adopt a factored model to parse the Simplified Chinese. The factored model is one kind of combined structure between PCFG structure and dependency structure. It mainly uses an extremely effective A* parsing algorithm which enables to get a more optimal solution. Throughout this paper, we use TCT Treebank as experimental data. TCT mainly consists of binary trees, with a few single-branch trees. The final experiment result demonstrates that the head propagation table improves the parsing performance. Finally, we describe the implementation of the system we used as well as analyze our experiment result SC_F1 from 43% up to 63% and the LC_F1 is about 92% we have achieved.
