基于语义模板的问答系统研究

Research on semantic pattern based question answering system

提出一个基于语义模板的用户交互问答系统,其中语义模板用于标识句子中各成分之间的语义关联关系.语义模板的使用有助于问题的分解和各成分间语义关联关系的研究,可提高分析精度,适宜于英文和中文问题的分析.在系统运行中,将问题和用户选择的正确答案对,存储在数据库中,通过积累知识构建知识库,实现问题自动回答.

A semantic pattern based user-interactive question answering system was proposed. The semantic pattern can sketch out the relationships among different elements in the sentence. The application of this semantic pattern in question parser improves the analysis of the relationships among sentence elements. Therefore, the accuracy of question analysis increase. It can be used for both English and Chinese question analysis. The knowledge base, which consisted of the pairs of question and correct answer selected by user, can be constructed during the running process of the system. The system can answer questions automatically by using the knowledge base.
