一种基于概念匹配度模型的中文问答系统

Chinese question answer system based on the model of the conceptual matching degree

答案抽取是问答系统的核心部分,本文根据汉语本身的特点,采用了本体论方法,借鉴了概念格的思想,提出了一种基于概念匹配度模型的中文问答系统。该系统通过计算与问题概念节点的匹配度,就可以抽取出查询问题的答案。该模型采用了定量计算,缩短了问题—答案匹配时间,并通过实例证明了该模型是有效的。

Answer extracting is central to question answer system. Chinese question answer system based on the model of the conceptual matching degree was put forward by using the ontological approach and using for reference from the concept lattice. This model can extract satisfied answer by calculating matching degree. The model adopts quantitative calculation and reduces the problem- - answer matching time.
