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
Gomez, D. ; Zarrazola, E. ; Yáñez, Javier ; Rodríguez, Juan Tinguaro ; Montero, Javier | World Scientific Publishing Company | 2014A crisp image segmentation can be characterized in terms of the set of edges that separates the adjacent regions of the segmentation. Based on these edges, an alternative way to define a fuzzy image segmentation is introduced in this paper. In t[...]texto impreso
Gomez, D. ; Rodríguez, Juan Tinguaro ; Yáñez, Javier ; Montero, Javier | Elsevier Science INC | 2016One of the main challenges of fuzzy community detection problems is to be able to measure the quality of a fuzzy partition. In this paper, we present an alternative way of measuring the quality of a fuzzy community detection output based on n-di[...]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
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[...]
