摘要 本体通过定义某一领域中概念及其概念之间的关系的规范描述,提供了语义上的知识表示和共享,实现了基于语义的案例匹配,本文对本体理论和知网理论等理论基础进行了研究,提出了基于本体的中文案例表示方法、基于知网的概念相似度计算方法、基于本体的中文案例相似度计算方法,提高了案例检索的查准率和查全率。 Defining the specification describes of concepts and their relationships in a particular field,Ontology can provide semantic-based knowledge representation and sharing, and realize the semantic intelligent case matching. The thesis studies on Ontology Theory and technology of"HowNet", and proposes the method of Case Representation based on Ontology、the method of Concept Similarity Computing based on"How Net"and the method of Case Similarity Computing based on Ontology, which can increase the precision rate an recall rate of Case Retrieval.
