Method of Similarity Calculation of Fuzzy Concepts

doi:-

Abstract

Abstract: Due to the fuzzy information cannot be handled by the classical approaches for ontology mapping and similarity calculation， the similarities between fuzzy concepts cannot be computed as well. To this end， a new method for similarity calculation of fuzzy concepts was 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 were firstly used to generate vector space model(VSM). And then the fuzzy concepts were represented as vectors in the VSM. Finally，the similarities for fuzzy concept pairs were obtained by calculating vectors. Therefore， the proposed SimFCVSM method can be used to calculate the similarity between fuzzy concepts based on VSM， effectively.

Key words: fuzzy ontology, fuzzy concept, similarity calculation, fuzzy relationship, vector space model
