✦ Synopsis
In this work, we introduce aggregation operators for linguistic labels this is, ordinal . Ž . scales when different experts or information sources use different domains to express Ž . their knowledge. The aggregated value is computed i building first a unified framework, Ž .
Ž . ii transforming all the initial values into this new framework, iii aggregating the Ž . transformed values, and iv finally applying a reversal transformation. Transformations and all the constructions are based on assuming an existing semantics for all the domains. Ž In this work, we consider the semantics based on the existence of an antonym or a set of . them for each element in the domain. This is equivalent to a semantics based on negation functions.
