摘　　要：与传统的基于框架的问句分析方法不同,本文结合汉语语法对问句的依存关系进行分析,提取问句的语义及问句各成分间的限制关系,得到主要针对领域本体知识库的问句理解结果。本文把问句分析细化为如下几个过程:命名实体识别、问句分类、问句预处理(包括:分词、词性标注以及句子解析)、问句焦点提取和问句成分间的语义关系及限制提取。最后通过实验验证算法的有效性。Combined with Chinese grammar,this paper proposes a new method of analyzing the dependency relation ship of interrogative sentences,which is different from the traditional analysis method of the interrogative sentence based on the frame.With this method,the semantic of the sentence and the restrict between the word of the sentence is extracted and the comprehension of the interrogative sentence on the search query of domain ontology knowledge base is obtained.The method includes five parts：recognizing the named entity,classifying the interrogative sentence,preprocessing the interrogative sentence（including participle,speech tagging and parse）,extracting the focus of the sentence,and extracting the semantic and restrict.Finally,the effectiveness of the algorithm is validated by the experiment.
