| 摘 要： | 对用户所提问句的理解是受限领域问答系统实现的关键，该文提出一种基于本体和问句句型模板规则的中文问句分析方法，研究如何使用问句语义表征来表示问句分析的结果，将该方法应用于某受限领域问答系统中。实验结果表明，使用该方法进行中文问句分析，准确率达90%以上，可以在实际的问答系统中使用该方法。

| Abstract: | Question parsing is one of the most important steps in the implementation of restricted-domain question answering system. This paper puts forward a new method to parse Chinese questions based on ontology and question semantic model, and explores how to use question semantic representation to represent the results of question parsing. A restricted-domain question answering system adopting this question parsing method is developed. Experimental results show that the precision of the method can exceed 90%, and it is feasible to use the method to develop restricted-domain question answering system. |
