基于改变历史日志扩展的本体映射进化研究

本体映射可以有效地解决本体异构问题,然而现有的本体映射研究大多只关注于映射方法本身,而缺乏在具体动态应用环境中对映射进化的分析,使得已有的本体映射方法在实际应用中的效率并不高。因此本文提出一种基于改变历史日志扩展的本体映射重建方法。该方法在本体映射进化时,用HL记录本体的变化对现有的映射系统进行扩展,仅仅更新过期的无效的映射对。实验结果表明,本文方法在本体不断更新的动态环境中表现较优,和其他现存映射进化系统相比具有时效性更高的优点。

Research on CHL extended ontology mappings updating

Ontology mapping can solve the problem of ontology heterogeneous effectively. However, most existing ontology mapping study only focused on mapping method itself and a lack of ontology conciliation analysis in practical dynamic environment result in a poor efficiency when the existing ontology mapping method put into practice .For addressing this issue, in this paper, an ontology mapping method with change history extended is proposed. When ontology mapping evolves, CHL (Change History Log) is used to record ontology changes and integrated with existing mapping systems. It is only stale and unreliable ones that are updated. Experimental results show that this method offers the benefits of re-establishing mappings among the updated ontologies. It drastically reduces the time required for updating mappings among ontologies.
