Concept similarity computation based on ontology and its application
Qi Li · Microcomputer & its Applications · 2010
This paper puts forward an integrated method based on semantic similarity and semantic relevancy. In semantic similarity, we think about the semantic distance and the characteristics of ontology, the concept’s amount of information, the depth of concept, the density of concept and symmetry factor; in semantic relevancy, we think about the directly relation and indirectly relation, direct inheritance and indirect inheritance. Compated with two traditonal semantic similarity computation methods, this method can better distinguish the different concept in ontology tree and this method is effective.
