本体映射过程中的结构相似度改进算法

Modified structure similarity algorithm in ontology mapping

概念的结构特性在本体映射中是个重要元素。针对目前结构相似度计算中存在不区分概念关系,没有考虑邻接节点相似度传播的权重的问题,提出一种结构相似度改进算法。它通过区分概念的非层次、层次关系,利用邻接节点贡献率对相似度传播加权,改进了结构相似度的映射性能。实验验证该算法是可行的。

Conceptual structure is important to similarity in the process of ontology mapping.This paper proposes a modified conceptual structure similarity algorithm against no distinguishing conceptual relations and no considering weight of adjacent nodes＇similarity spread.By distinguishing between hierarchical relations and no hierarchical relations and calculating adjacent node contribution rate as weight of similarity,it improves mapping performance.The experiment shows that the algorithm is viable.
