This paper analyzes the relationship between fuzziness and bipolarity, notions which were devised to address different kinds of uncertainty: linguistic imprecision, in the former, and knowledge relevance and character or polarity, in the latter.[...]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
Montero, Javier ; Bustince, H. ; Franco, C. ; Rodríguez, Juan Tinguaro ; Gómez, Daniel ; Pagola, Miguel ; Fernandez, Javier ; Barrenechea, Edurne | University of Copenhagen, Department of Food and Resource Economics | 2014In this strictly positional paper we propose a general approach to bipolar knowledge representation, where the meaning of concepts can be modelled by examining their decomposition into opposite and neutral categories. In particular, it is the se[...]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[...]texto impreso
Montero, Javier ; Bustince, H. ; Franco, C. ; Rodríguez, Juan Tinguaro ; Gómez, Daniel ; Pagola, M. ; Fernández, J. ; Barrenechea, E. | Elservier | 2016In this position paper we propose a consistent and unifying view to all those basic knowledge representation models that are based on the existence of two somehow opposite fuzzy concepts. A number of these basic models can be found in fuzzy logi[...]texto impreso
Rodríguez, Juan Tinguaro ; Rios, Camilo Franco de los ; Montero, Javier ; Lu, Jie | Springer- verlag | 2014The evidence coming from cognitive psychology and linguistics shows that pairs of reference concepts (as e. g. good/bad, tall/short, nice/ugly, etc.) play a crucial role in the way we everyday use and understand natural languages in order to ana[...]texto impreso
In this paper we consider a complete fuzzy preference structure, defined by means of a constructive approach associated to the necessary learning process in a decision making problem. Preference relations are successively assigned over a given s[...]texto impreso
Different types of inexactness can be represented by fuzzy sets: vagueness, where there are no precise boundaries, ambiguity, when more than one distinguishable concept is described, generality, such that a word applies to a variety of situation[...]texto impreso
Abstract Fuzzy preference and aversion relations allow measuring in a gradual manner the attitude of the individual regarding some pair of alternatives. Following the Preference-Aversion (PA) model, previously introduced for identifying the subj[...]texto impreso
Classification problems often play an important role in many decision contexts. Therefore, the design of decision support tools to operate in such contexts usually involves the formulation of adequate classification models. Fuzzy rule-based clas[...]texto impreso
Guada, Carey ; Gomez, D. ; Rodríguez, Juan Tinguaro ; Yáñez, Javier ; Montero, Javier | CAEPIA'15 | 2015El propósito de este trabajo es presentar una forma de como obtener una segmentación borrosa de imágenes a través de un algoritmo de segmentación jerárquica de imágenes. En primer lugar, para alcanzar este objetivo, se definen dos maneras de seg[...]texto impreso

A menudo, el conjunto de clases de un problema de clasificación presenta una estructura en relación con las características propias de cada contexto de aplicación. Sin embargo, los modelos de clasificación habituales no suelen contemplar esa est[...]texto impreso
Properties related with aggregation operators functions have been widely studied in literature. Nevertheless, few efforts have been dedicated to analyze those properties related with the family of operators in a global way. What should be the re[...]texto impreso
Montero, Javier ; Rodríguez, Juan Tinguaro ; Gomez, D. ; Bustince, H. ; Fernandez, J. F. | Edicions UIB | 2009This paper stresses the relevance of taking into account that quite often information is structured, and therefore a standard aggregation focuss may produce misleading results, if such an approach assumes in fact that information does not presen[...]texto impreso
Aggregation functions have been widely studied in literature. Nevertheless, few efforts have been dedicated to analyze those properties related with the family of operators in a global way. In this work, we analyze the stability in a family of a[...]texto impreso
Rojas, Karina ; Gómez, Daniel ; Montero, Javier ; Rodríguez, Juan Tinguaro | Elsevier Science BV | 2013-10-01In this paper we analyze the notion of family of aggregation operators (FAO), also refereed to as extended aggregation functions (EAF), i.e., a set of aggregation operators defined in the unit interval which aggregate several input values into a[...]texto impreso
In this reviewing paper, we recall the main results of our papers [24, 31] where we introduced two paraconsistent semantics for Pavelka style fuzzy logic. Each logic formula a is associated with a 2 x 2 matrix called evidence matrix. The two sem[...]texto impreso
In this paper we revise the three types of bipolarity recently proposed by Dubois and Prade, focussing on how the basic structure is being built up. In this way we can clarify key differences between them, and formalize to what extent some struc[...]texto impreso
En este artículo se presentan los resultados de una experiencia realizada con dos grupos de alumnos,uno de Ciencias Sociales y otro de Ciencias Matemáticas, con la finalidad de observar las posibles disimilitudes en la percepción y uso de difere[...]texto impreso
El objetivo de esta comunicación es proponer una ormulación axiomática del concepto de antagonismo semántico,relacionando dicha formulación con la de antónimo. Particularmente,la noción de antónimo está estrechamente ligada a polaridades lingüís[...]texto impreso
El objetivo de este trabajo es presentar una metodología que permita clarificar las relaciones existentes entre las nociones de incertidumbre borrosa (fuzziness) y bipolaridad. Esta metodología está basada en el uso de extensiones continuas 4-va[...]
