Resumen de Conceptual negations of statements: "X is A"

E. Puerto, G. Hunault, D. Pacholczyk

• We show here how to represent formally the linguistic negation of statements like in "X is not A". To do so, we define the notions of predicative concept, of rejection and of maximalconceptual negation. We also use a similarity between predicats of a same concept to choose a particular graded negation among other possible negations.
