Abstract

In this work we propose a fuzzy free logic, that is a generalized system which can give proper interpretation to sentences containing vagueness of non-referring singular terms. This logic is an amalgamation of classical positive free logic system with predicate rational Pavelka logic. The semantics given to the fuzzy free logic is based on dual-domain semantics. A graded similarity measure is introduced in the system which allows comparing two objects based on some properties and assign a degree of similarity. Soundness of the proposed system is proved.
