摘要
问题分类是问答系统的一个非常基础而重要的子模块。以问题的语义信息为分类依据,建立了一个新的问题分类体系,并提出了一种基于《知网》的自动分类方法。利用该方法对507个问题进行分类实验。实验中问题分类的平均召回率为93.72%,平均正确率为82.23%。实验结果表明,该分类方法是有效的并且以语义信息作为分类依据是可行的。
Question Classification is a fundamental and very important sub - module of Question Answering system. Taking the semantic information of questions as a criterion of Question Classification, a new classification system is proposed, and then a HowNet based automatic classification approach is presented. After that , the method is utilized to make classification experiments with 507 questions, the average recalling rate and precision rate achieve 93.72% and 82.23% respectively. The experiment＇s result shows that the classification method proposed here is valid, and it is feasible to take semantic Information as a criterion of classification.
