本体技术在语义博客中的应用研究

摘要

With the research on ontology language OWL, a semantic retrieval model base on ontology and lucene is proposed. A semantic blog with full text retrieval and semantic retrieval is build, using domain ontology database to extend user's query condition. According to the test result, the new technology is feasible, and it gives higher precision rate and better recall rate, which could provide us a better retrieval system.%研究了本体描述语言OWL,提出并实现了一个基于本体和Lucene的语义检索模型,利用领域本体知识库对用户的查询要求进行语义扩展,构建了具有全文检索和语义检索功能的语义博客系统.实验证明语义检索方案在运行效能上可行,并且可以提供更高的查准率和查全率,对改进当前的检索系统是具有一定积极意义的.
