On consistency and coverage measures in the fuzzified set-theoretic approach for social sciences: dealing with ambivalent evidence in the data
Original language description
This paper investigates the modified concepts of fuzzy consistency and fuzzy coverage recently proposed by Stoklasa et al. in the context of the fuzzified set- theoretic approach for the purpose of linguistic/fuzzy rule validation in social sciences. The new fuzzified consistency and coverage measures (denoted by the F2 and F3 indices in the paper by Stoklasa et al.) were introduced in 2017 as a reaction to the inability of the original consistency and coverage fuzzified by Ragin in 2008 to deal with ambivalent information present in the data. More specifically, the F2 and F3 measures try to remove the ambivalent information inherent in the fuzzy observations - i.e. observations with fuzzy values ofsome or all of the relevant variables. We analyse the performance of all three consistency and coverage measures, assess the ability of the new ones to deal with the ambivalent information and propose a modification of the F3 consistency and coverage which increases its distinguishing power. We present graphical summaries of the performance of the consistency and coverage measures for a single-fuzzy-observation case and discuss their possible usefulness and differences.
