用数据挖掘和本体实现空间信息系统语义互操作

Using Data Mining and Ontology to Realize Interoperability Geographic Information Systems

介绍了一种利用数据挖掘和本体实现信息系统互操作的新方法 .该方法通过基于本体的逻辑推理实现概念语义在不同空间信息系统之间的转换 ,利用数据挖掘技术从候选集合中确定转换集合并将操作的结果返回给用户 ,从而完成空间信息系统的互操作 。

This paper introduces a new mechanism to realize the semantic interoperability of Geographic Information Systems. Firstly we demonstrate the validity of the mechanism (or hypothesis) of using ontology to realize the semantic interoperability. Secondly we discuss detailedly how ontology and data mining work as the foundation of this mechanism. By semantic relation of the ontologies, we can construct an integrated ontology which comes from difference ontology systems. By data mining, the mechanism can make sure that the convert set of the ontology is discussed and the convert set comes from another ontology system. By using the convert set user's operations are rewritten and carried out so that the translations across these ontology systems are obtained. So the robustness and scalability of the semantic interoperability of Geographic Information Systems are improved.
