摘要: 研究语义网技术在数据集成中的应用方法。采用规则系统实现对语义网本体语言的扩展,以提高本体语言的表达能力。在此基础上将语义网相关技术系统地应用到数据集成系统的各个方面,包括数据采集、本体构建、本体映射、数据查询和数据持久化。通过一个实例,展示了上述方法的可行性。Abstract: This paper addresses semantic Web based approach for data integration. To improve its expressivity, the semantic web ontology language is extended by a rule-based system. Semantic Web technique is systematically applied to various aspects of an ontologybased data integration system, including data extraction, ontology building, ontology mapping, data query, and data persistence. Finally, a case study is presented to show the feasibility of this proposed method.
