Abstract: In natural language parsing, probabilistic context-free grammar (PCFG) is a common model used in disambiguation. In this paper, we combine PCFG with context-sensitive probabilistic information, and propose a new disambiguation method. This method can effectively improve the correctness of syntactic disambiguation. ;;
