摘要： 针对词汇化树邻接文法的歧义现象,利用《知网—信息结构库》作为知识库,并引入概率方法提出了一种有效的句法树消歧方法。文中阐述了如何利用知网信息结构模式对句法树进行筛选,并提出了基于概率的信息结构抽取的计算方法。

Abstract: Considering the disambiguation of syntactic tree generated by lexicalized tree adjoining grammar, a statistical approach efficiently solves the disambiguation of syntactic tree using message structure pattern of HowNet as knowledge database. The method to select a optimal syntactic tree based on message structure pattern, and a statistical approach of extracting message structure are presented.
