摘要
本体匹配是建立两个本体之间映射关系的过程,一个高效、严格的相似度计算方法是本体匹配的前提条件,为此提出了一种基于RDF图匹配的方法。该方法用RDF图表示本体,使本体间的匹配问题转化为RDF图的匹配问题,并利用匹配树表示匹配的状态,通过匹配树计算出两个本体中各实体之间的相似度,进而得到两个本体之间的映射关系。实验结果表明,该方法在查全率和查准率方面都有很好的表现。
Ontology matching is the operation that builds the mapping of two ontologies, and an efficient and rigorous similarity measure is a pre-requisite of an ontology matching process. An ontology matching approach was put forward. It used Resource Description Framework （RDF） graph to express ontology and converted the ontology matching to the problem of building RDF graph matching tree. Moreover, the proposed approach presented a similarity measure based on the entities of nodes from the matching tree to obtain the mapping of the two ontologies. Implementation and experimental results were given to demonstrate the effectiveness of the matching approach.
