In traditional logic, every statement is either true or false. In real life, people are often not certain about their statements. Zadeh proposed to describe different degrees of certainty by numbers from the interval \([0,1]\); this is one of the main ideas behind \textit{fuzzy logic}.

On antonym and negate in fuzzy logic
International Journal of Intelligent Systems, 1999The paper analyses the antonyms in natural language and the possibility to model their meaning using fuzzy set theory. The presentation is extensional, when the meaning of words of natural language is modeled using fuzzy sets being functions on some universe. A specific case is supposed when the universe is formed by an interval of real numbers.

SymmetryIn this paper, we present two new classes of fuzzy negations. They are an extension of a well-known class of fuzzy negations, the Sugeno Class. We use it as a base for our work for the first two construction methods.

Residuated fuzzy logics with an involutive negation
Archive for Mathematical Logic, 2000Residuated fuzzy logic calculi are related to continuous t-norms, which are used as truth functions for conjunction, and their residua as truth functions for implication. In these logics, a negation is also definable from the implication and the truth constant 0̄, namely ¬φ is φ → 0̄.

FLcom is a fuzzy propositional logic with contradictory negation, opposite negation and medium negation which corresponds to fuzzy set FScom. Based on theories of FLcom, this paper took a financial decision making for example, adopted Distance Ratio Function to give an evaluation to fuzzy propositional, gave a method to ascertain value of ( in the ...
