摘要
相似度传播是本体映射中结构策略的实质内容。然而,目前的相似度传播算法却没有对相似度传播值进行合理的定量分析。针对此问题,提出了基于概念信息量的相似度传播算法,该算法根据已匹配节点的概念信息量大小来判断其子父节点匹配概率大小,通过匹配概率大小调整相似度传播值,从而进行更精确的相似度传播,提高结构策略的可信度。理论分析与实验结果证明了该算法是有效的。
Similarity propagation is essential step for structure strategy.However,the existing algorithm of similarity propagation does not take a reasonable quantitative analysis for propagated value.To solve this problem,a new algorithm of similarity propagation is proposed which based on information content of concept, information content of concept is acquired by the context of ontology structure, and propagated value is adjusted by the value of information content of concept to obtain a more accuracy propagated value.Theoretical analysis and the results of experiment is shown that the improved algorithm is efficient.
