中文摘要：

随着本体在数据集成方面的广泛应用,面向本体的概念相似度计算成为人们关注的热点问题.针对当前领域本体概念相似度的计算过程都比较复杂的问题,提出一种基于树结构的本体概念相似度的计算方法.该方法通过添加和重组虚拟节点重构本体树,再通过属性比较映射对象,最后通过计算,得到本体概念的语义相似度结果.实验结果表明,该方法有效利用了本体概念的语义信息,得到了合理的计算结果,并简化了计算过程.

英文摘要：

With the wide application of ontology in data integration, the concept of ontology-oriented similarity calculation became a hot issue of concern. In view of the problems that current domain ontology concept similarity calculation processes are complex, this paper proposes a concept of ontology similarity calculation method based on tree structure. The thought of this method is that through adding virtual nodes and restructuring, refactoring ontology tree, and then comparing and mapping object properties, at last, the computation of the concept of ontology semantic similarity results are obtained. The experimental results show that the method is effective to use the concept of ontology semantic information, reasonable calculation results are obtained, it can also simplify the calculation process.
