Fuzzy Logic in Narrow Sense with Hedges
Classical logic has a serious limitation in that it cannot cope with the issues of vagueness and uncertainty into which fall most modes of human reasoning. In order to provide a foundation for human knowledge representation and reasoning in the presence of vagueness, imprecision, and uncertainty, fuzzy logic should have the ability to deal with linguistic hedges, which play a very important rol...
متن کاملA Fuzzy Description Logic with Hedges as Concept Modifiers
In this paper we present a fuzzy description logic , where primitive concepts are modified by means of hedges. is strictly more expressive than Fuzzydefined in [8]. We show that given a linearly ordered set of hedges primitive concepts can be modified to any desired degree by prefixing them with appropriate chains of hedges. Furthermore, we define a decision procedure for the unsatisfiability p...
متن کاملA parametric representation of linguistic hedges in Zadeh's fuzzy logic
This paper proposes a model for the parametric representation of linguistic hedges in Zadeh’s fuzzy logic. In this model each linguistic truth-value, which is generated from a primary term of the linguistic truth variable, is identified by a real number r depending on the primary term. It is shown that the model yields a method of efficiently computing linguistic truth expressions accompanied w...
متن کاملMathematical Fuzzy Logic In Narrow And Broader Sense — A Unified Concept
The main idea motivating the development of fuzzy logic (FL) can be formulated as follows: Fuzzy logic is a special many-valued logic addressing the vagueness phenomenon and developing tools for its modeling via truth degrees taken from an ordered scale. It is expected to preserve as many properties of classical logic as possible. During the past 15 years, the mathematical FL has been developed...
متن کاملIn Which Sense Is Fuzzy Logic a Logic for Vagueness?
The problem of artificial precision demonstrates the inadequacy of näıve fuzzy semantics for vagueness. This problem is, nevertheless, satisfactorily remedied by fuzzy plurivaluationism; i.e., by taking a class of fuzzy models (a fuzzy plurivaluation), instead of a single fuzzy model, for the semantics of a vague concept. Such a fuzzy plurivaluation in turn represents the class of models of a f...
