Abstract: Auto generation of chart parser will greatly improve the developping efficiency of natural language processing project. This paper presents an algor ithm for generating chart parser supporting complicated features and unification grammar and describes rules, output code pattern and main algorithms used in au to generation. At the same time, it develops an auto generating system, experime nt on which shows that the system not only works well but also improves the scal ability of syntax analysis effectively.
