Negation of Fuzzy-Linguistic Concepts in Hierarchical Domains

Grzegorz Popek

Abstract: The 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 reflecting a use of negation in domains in which fuzzy-linguistic concepts are organised into a hierarchy.
