CHINESE CCG PARSING BASED ON A*SEARCH AND SUPERTAGGING
摘要
Abstract
Chinese CCG is difficult to parse,in light of this character,in the paper we investigate the way to integrate two independenttechniques on Chinese CCG parsing.Firstly the supertagging is used,and by eliminating with log-linear model those words categories whosepossibility is low,the latent parsing space of sentences is pruned.Secondly,A* search is applied to further accelerate the parsing procedure.At last the verifications are done on the approach used from the dimensions of both time efficiency and parsing accuracy.Experiments indicatethat the parsing algorithm based on A* search and supertagging can significantly improve the efficiency and accuracy.关键词
