摘要
研究了一种基于结构化问句实例分析问句的方法,设计了应用该方法时的各种语义知识及其表示,用Xml文档来管理领域知识,在这种知识结构上设计了一种答案抽取的方法。在此基础上,开发了BAQS的原型系统。实验表明方法可行,准确率和召回率可分别达到82.05%和91.95%。对问答系统的设计具有借鉴意义和继续深入研究的价值。
It studys a kind of method to analysis question sentence based on the structural question sentence instance, design a method to express various kind of semanteme knowledge, manage domain knowledge in Xml file, and design a method to extract answer on the kind of knowledge structre. The system of BAQS has developed. The experiment indicat- ed that the method is feasible, The rate of accuracy and recalling can be up to 82.05% and 91.95%, For it use in a bank question-answering-system and the experiments proved that it was feasible to use the method to analyze question clause and valuable to continue to study it deeply,
