| 摘 要： | 查询扩展是优化信息检索的一种有效方法。基于关键词的查询扩展对语义信息的忽略为结果带来了不好的影响，因而提出一种基于本体的查询扩展方法。首先建立本体模型，通过计算本体中的概念语义相似度和实例语义相似度，实现语义查询扩展。

| Abstract: | Query Expansion is an effective way to optimize information retrieval. Query expansion based on Key words results in a bad effect because of losing sight of the semantic information. Therefore a query expansion method based on ontology is proposed. Firstly,an ontology model is built. Then,semantic query expansion is carried out,through computing the concept semantic similarity and entity semantic similarity based on ontology. |
