摘　　要：随着本体的增多,本体异构是本体间互操作的主要障碍,阻碍了本体信息共享,解决本体异构最好的方法是本体映射。本体映射的关键是概念相似度的计算,但现今的计算模型考虑的影响因素比较单一。结合距离语义相似度和属性语义相似度,提出了一种综合语义相似度计算方法。实验证明,该方法可以提高计算结果的精确度。With the radual increasing of Ontological, ontology heterogeneity is the primary obstacle for interoperation of ontology. It baffled the share of the ontology information. Ontology mapping is the best way to solve the problem. The key of ontology mapping is to compute similarities between concepts. But, currently , the compute model only solved simplex factor. In this paper, an integrate concept similarity computing approach was proposed. The approach both distance semantic similarity and property semantic similarity Experiments results show that this calculative method can improve the precision of calculative results.
