✦ Synopsis

This paper describes a classification of semi-fuzzy quantifiers that considerably improves the division between what Zadeh calls quantifiers of the first kind and those of the second kind. A number of cases are contemplated that are not habitually described in the literature on fuzzy quantification (e.g., comparative and exception quantifiers). Models are also defined for all the types of semi-fuzzy quantifiers framed in the classification. Thus in order to construct fuzzy quantifiers it is sufficient to apply a suitable quantifier fuzzification method. This paper also deals with the application of semi-fuzzy quantifiers and fuzzy quantifiers to fuzzy relations. The solution of this problem is of interest in various fields; amongst which, perhaps the most noteworthy is that of fuzzy databases.

Lindström (Theoria, 1966; 32:186-195) introduced a very powerful notion of quantifiers, which permits multiplace quantification and the simultaneous binding of several variables. "Branching" quantification was found to be useful by linguists, e.g., for modeling reciprocal constructions like "Most me

A fuzzy extension of the Rand index [Rand, W.M., 1971. Objective criteria for the evaluation of clustering methods. J. Amer. Statist. Assoc. 846-850] is introduced in this paper. The Rand index is a traditional criterion for assessment and comparison of different results provided by classifiers and

In this paper, we model the evaluation of soft conditional preferences in flexibly querying fuzzy databases. We assume that soft conditional preferences are expressed in the form "If C then Q1 is better than Q2," where C is the primary condition, and Q1, Q2 are the conditions with preferences. They
