Wang, Xuzhu; De Baets, B.; Kerre, E. A comparative study of similarity measures. (English) Zbl 0852.04011 Fuzzy Sets Syst. 73, No. 2, 259-268 (1995). Summary: The purpose of this paper is twofold. Firstly, we would like to comment on the study of similarity measures carried out by C. P. Pappis and N. I. Karacapilidis [ibid. 56, 171-174 (1993; Zbl 0795.04007)]. Their definition of ‘approximate equality’ of fuzzy sets is modified and relevant properties related to this correlated definition are listed. Secondly, a new class of similarity measures, extracted from the work of W. Bandler and L. Kohout [ibid. 4, 13-30 (1980; Zbl 0433.03013)] on fuzzy power sets, is presented. The properties of the concept of approximate equality corresponding to these similarity measures are discussed, and involve a study of implication operators.
