Method of Similarity Calculation of Fuzzy Concepts
Zhang Ling-y · Journal of Northeastern University · 2013
Due to the fuzzy information cannot be handled by the classical approaches for ontology mapping and similarity calculation,the similarities betw een fuzzy concepts cannot be computed as w ell.To this end,a new method for similarity calculation of fuzzy concepts w as provided based on vector space model,called Sim FC-VSM(similarity of fuzzy concept based on vector space model).The fuzzy relationships in fuzzy ontologies w ere firstly used to generate vector space model(VSM).And then the fuzzy concepts w ere represented as vectors in the VSM.Finally,the similarities for fuzzy concept pairs w ere obtained by calculating vectors.Therefore,the proposed Sim FC-VSM method can be used to calculate the similarity betw een fuzzy concepts based on VSM,effectively.
