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.

Interval Negation in Fuzzy Logics
NAFIPS 2007 - 2007 Annual Meeting of the North American Fuzzy Information Processing Society, 2007This paper continues investigation of systems of fuzzy interval logics based on the Checklist Paradigm semantics of Bandler and Kohout. The paper looks at the alternative negations that may appear in the interval system rti\. In the previous papers dealing with checklist paradigm based interval systems the 2ary connectives were the interval connectives

On the negation of bipolar fuzzy conditions
2011 Annual Meeting of the North American Fuzzy Information Processing Society, 2011This paper deals with the negation operator in the context of a bipolar fuzzy relational algebra which makes it possible to handle bipolar fuzzy queries (involving flexible constraints and wishes) and relations. Several possible definitions of the negation are studied and assessed with respect to some desirable properties.

Negation of Fuzzy-Linguistic Concepts in Hierarchical Domains
2016 Third European Network Intelligence Conference (ENIC), 2016The great part of fuzzy-linguistic research assumes the fuzzy complement as a good candidate for representing the meaning of negation. However, linguistic studies show that both acquisition and use of negation are way more complex than that. After reconsidering a way in which the negation is used in the natural language discourse, this paper focuses on

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.

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 ...

Fuzzy Implications Generating from Fuzzy Negations
2018A basic building block in the foundation of fuzzy neural networks is the theory of fuzzy implications. Fuzzy implications play a crucial role in this topic. The aim of this paper is to find a new method of generating fuzzy implications. based on a given fuzzy negation.
