综合多层信息的本体概念相似度计算方法的研究

Research on an ontology concept similarity calculation approach based on the integrated multilayer information

提出了一种综合多层信息的本体概念相似度计算方法。首先从概念的单层信息出发,分别计算概念的语义、语用以及字面3个层面的相似度,在此基础上,对各层面相似度进行综合计算,得到能够更加全面的描述概念整体特征的综合相似度。实验结果表明,与基于单层信息的概念相似度计算方法相比,综合相似度计算方法能够有效提高计算精度,与人类主观判断的结果更加吻合。

A new ontology concept similarity calculation approach based on the integrated multilayer information was proposed. The approach started from the single-layer information of concepts, calculated the semantic, pragmatic and literal similarity respectively, and then integrated these similarities according to a certain integrated method, lastly, got the integrated similarity which described concepts more entirely. Experimental result demonstrates that, comparing with the methods based on single-layer information, the integrated approach improves the precision of concept similarity calculation effectively, and the calculation results inosculate with subjective judgment more tightly.
