Rodríguez, Juan Tinguaro ; Franco, Camilo ; Vitoriano, Begoña ; Montero, Javier | Society for soft computing | 2011The concept of semantic antagonism refers to the human capability of characterizing those objects of an universe of discourse being dissimilar, significantly different from or opposite to a given concept, predicate or previous knowledge. This ca[...]texto impreso
Franco, Camilo ; Rodríguez, Juan Tinguaro ; Montero, Javier | World Scientific Publishing Company | 2014The polarity of concepts and the dialectic process by which its meaning emerges has been subject of interest since the ancient Greeks. Recently, the term Bipolarity has been used in social and mathematical sciences, referring to the measurement [...]texto impreso
Making decisions by learning preferences requires to consider semantical aspects dealing with the meaning and use of the preference concept. Examining recent developments on bipolarity, where concepts are measured/verified regarding a pair of op[...]texto impreso
García-Santesmases, J M ; Franco, Camilo ; Montero, Javier | World Scientific Publ Co Pte Ltd | 2012In this paper we consider consensus measures for a group of individuals that answer a single question on an ordinal Likert-type scale that represents the ratings or rankings of each individual preference. The measure we propose satisfies the rul[...]texto impreso
This paper studies the meaning of fuzzy preference under the light institionistic fuzzy sets. Intuitionism is revisted and intuitionistic fuzzy prefrerence relations are defined. A linguistic interpretation of strict and weak fuzzy preference is[...]texto impreso

Preference semantics examine the meaning of the preference predicate, according to the way that alternatives can be understood and organized for decision making purposes. Through opposite-based semantics, preference structures can be characteriz[...]texto impreso
Este artículo presenta un modelo de preferenciaaversión (P-A), el cual permite representar el proceso mediante el que un individuo racional (bajo una racionalidad de pérdidas y ganancias) ordena sus alternativas, en base a la agregación independ[...]texto impreso
Montero, Javier ; Rodríguez, Juan Tinguaro ; Franco, Camilo ; Bustince, Humberto ; Barrenechea, Edurne ; Gómez, Daniel | Springer | 2014In this paper, we want to stress that bipolar knowledge representation naturally allows a family of middle states which define as a consequence different kinds of bipolar structures. These bipolar structures are deeply related to the three types[...]texto impreso
This paper proposes a novel approach to analyze the relationship between interval valued fuzzy sets (IVFS) and Atanassov’s intuitionistic fuzzy sets (AIFS), based on the recently introduced notion of paired structure. It is suggested that the di[...]texto impreso
A general overview of partial comparability and preference theory allows examining the notion of bipolarity and its role in the development of some general preference structures. This bipolar approach comes natural to the framework of decision t[...]texto impreso
In this paper we stress the relevance of those fuzzy models that impose a couple of simultaneous views in order to represent concepts. In particular, we point out that the basic model to start with should contain at least two somehow opposite va[...]texto impreso
In this paper we want to stress the relevance of paired fuzzy sets, as already proposed in previous works of the authors, as a family of fuzzy sets that offers a unifying view for different models based upon the opposition of two fuzzy sets, sim[...]texto impreso
Rodríguez, Juan Tinguaro ; Gómez, Daniel ; Yáñez, Javier ; Montero, Javier ; Franco, Camilo | Atlantis Press | 2015In this paper we present a new class of fuzzy sets, paired fuzzy sets, that tries to overcome any conflict between families of fuzzy sets that share a main characteristic: that they are generated from two basic opposite fuzzy sets. Hence, the fi[...]texto impreso
Opposition-based models are a current hot-topic in knowledge representation. The point of this paper is to suggest that opposition can be in fact introduced at two different levels, those of the predicates of interest being represented (as short[...]
