摘要: 为减少映射查找时相似度的冗余计算,改善映射查找效果,提出了一种通过考察待查概念与已有映射概念之间的邻近度,来推断待查概念映射关系的映射重用算法。构建概念描述概要间的语义二分图联系,从最佳匹配的角度,计算已有映射中概念与待查概念间的邻近程度,以已有映射中概念的邻近概念具有相似映射关系为前提,根据概念间相似度传递性决定待查概念间的映射关系。实验结果表明,该映射重用算法明显改善了映射查找的效果。

Abstract: To reduce the redundant similarity calculations and improve the mapping discovery, by considering the neighboring similarity among the concepts to be investigated and the concepts in the existing mapping which could infer the new mappings, an ontology mapping reuse algorithm was proposed. Firstly, a semantic bipartite graph between the concepts profile was established. Then, the neighboring concepts similarity from the best match of the bipartite graph was obtained. Finally, inspired by the similarity transmission among neighboring concepts, the new mapping among the concepts was decided by their neighboring similar concepts existing mapping. Experimental results showed that the proposed algorithm could improve the mapping discovery.

Key words: ontology, mapping reuse, bipartite graph, neighboring concepts similarity
