Fuzzy-Valued Similarity Measures

Abstract

The assessment of the similarity or compatibility analyzes common features or properties and encapsulates the degree of compatibility in a predetermined format. In the preceding chapters, the measurement of the compatibility of fuzzy sets has been scalar-valued. The summarization of similarity as fuzzy sets rather than single numbers was suggested by Dubois and Prade [63] and is analogous to the use of fuzzy truth values in reasoning with linguistic variables as discussed in the preceding chapter.
