This paper presents our work for participation in the 2012 CIPS-ParsEval shared task of Simplified Chinese parsing. We adopt a fac-tored model to parse the Simplified Chinese. The factored model is one kind of combined structure between PCFG structure and de-pendency structure. It mainly uses an extreme-ly effective A * parsing algorithm which ena-bles to get a more optimal solution. Through-out this paper, we use TCT Treebank as exper-imental 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 per-formance. Finally, we describe the implemen-tation 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. 1
