摘　　要：本体通常用来描述内容的语义,以实现基于语义的内容共享和集成。然而,手工构建本体通常耗费巨大,使得本体构建成为一项艰巨的任务。因此,有必要研究基于结构化数据的本体学习技术。提出了从关系数据库中学习本体的方法,定义了关系数据源到本体的映射规则并与现有方法进行了详细的比较,同时给出了应用实例及原型实现。分析表明,与现有方法相比,本文提出的方法在映射的完整性及正确性方面有较大提高。The body is usually used to describe the semantics of the content in order to achieve semantic-based content sharing and integration.However,the manually constructed ontology is usually costly,the ontology construction is a difficult task.Therefore,it is necessary to study the structured data-based ontology learning techniques.Learning ontology from relational database,the definition of a relational data source to the ontology mapping rules and a detailed comparison with existing methods,and application instance and prototype implementation.The analysis showed that compared with existing methods,the proposed method has improved greatly in the integrity and accuracy of mapping.
