Cordero-Ortega, Pablo; Enciso-García-Oliveros, Manuel
; López-Rodríguez, Domingo
; Mora-Bonilla, Ángel
(Elsevier, 2020-09-15)
Graded implications in the framework of Fuzzy Formal Concept Analysis are used as the knowledge guiding the recommendations. An automated engine based on fuzzy Simplification Logic is proposed to make the suggestions to ... -
A generalized framework to consider positive and negative attributes in formal concept analysis
Rodríguez Jiménez, José Manuel; Cordero-Ortega, Pablo; Enciso-García-Oliveros, Manuel
; Mora-Bonilla, Ángel
(2014-10-23)
In Formal Concept Analysis the classical formal context is analized taking into account only the positive information, i.e. the presence of a property in an object. Nevertheless, the no presence of a property in an object ... -
A logic-based approach to compute a direct basis from implications
Cordero-Ortega, Pablo; Enciso-García-Oliveros, Manuel
; Mora-Bonilla, Ángel
; Ojeda-Aciego, Manuel
; Rodríguez-Lorenzo, Estrella (2014-09-19)
Formal Concept Analysis is an emergent area in the topic of data analysis based on lattice theory. In this framework, a context is defined as the relation between a set of objects and a set of attributes and from here it ... -

CAISL: Simplification Logic for Conditional Attribute Implications
Mora-Bonilla, Ángel; Cordero-Ortega, Pablo
; Enciso-García-Oliveros, Manuel
; Rodríguez-Lorenzo, Estrella; Missaoui, Nokia (2016-07-25)
In this work, we present a sound and complete axiomatic system for conditional attribute implications (CAIs) in Triadic Concept Analysis (TCA). Our approach is strongly based on the Simplification paradigm which offers a ... -

Guerrero Pertíñez, María del Pilar (2017-02-09)En este trabajo fin de grado se evalúan los parámetros más relevantes del rendimiento de un escáner de tomografía por emisión de positrones (PET), dedicado a la imagen de animal pequeño. Para ello se han seguido los ... -
Clasificación y respuesta automática de correos electrónicos mediante herramientas de análisis de datos
Ruiz Luque, José Manuel (2020-11-17)Con este estudio nuestro objetivo es reducir el tiempo de trabajo de los empleados de una empresa, haciendo que se centren en la respuesta a correos más individualizados mientras que los correos generales se respondan ... -
Dimensional synthesis of mechanisms using Differential Evolution with auto-adaptive control parameters.
Ortiz-Fernández, Antonio; Cabrera-Carrillo, Juan Antonio
; Nadal-Martínez, Fernando
; Mora-Bonilla, Ángel
(Elsevier, 2013-06)
This paper presents how an algorithm based on Differential Evolution (DE) with no constant control parameters solves the dimensional synthesis of four and six-bar mechanisms for path generation. The selection of values ... -
Extending FuzAtAnalyzer to approach the management of classical negation
Rodríguez-Jiménez, J.M.; Cordero-Ortega, Pablo; Enciso-García-Oliveros, Manuel
; Mora-Bonilla, Ángel
(2015-09-16)
FuzAtAnalyzer was conceived as a Java framework which goes beyond of classical tools in formal concept analysis. Specifically, it successfully incorporated the management of uncertainty by means of methods and tools from ... -
fcaR, Formal Concept Analysis with R.
Cordero-Ortega, Pablo; Enciso-García-Oliveros, Manuel
; López-Rodríguez, Domingo
; Mora-Bonilla, Ángel
(The R Foundation, 2022)
Formal concept analysis (FCA) is a solid mathematical framework to manage information based on logic and lattice theory. It defines two explicit representations of the knowledge present in a dataset as concepts and ... -
From an implicational system to its corresponding D-basis
Rodríguez-Lorenzo, Estrella; Adaricheva, Kira; Cordero-Ortega, Pablo; Enciso-García-Oliveros, Manuel
; Mora-Bonilla, Ángel
(2015-10-30)
Closure system is a fundamental concept appearing in several areas such as databases, formal concept analysis, artificial intelligence, etc. It is well-known that there exists a connection between a closure operator on a ... -
Herramientas online para ayudar a los estudiantes en las asignaturas de matemáticas
Gómez Lobato, Delia (2022-09)En estos últimos años, hemos sido testigos de cómo ha incrementado la necesidad de disponer de material online para facilitar y complementar el aprendizaje, sobre todo debido a la pandemia que hemos vivido, provocando ... -
Inference of mixed information in Formal Concept Analysis
Mora-Bonilla, Ángel; Cordero-Ortega, Pablo
; Enciso-García-Oliveros, Manuel
; Rodríguez, Jose Manuel (2017-10-10)
Negative information can be considered twofold: by means of a negation operator or by capturing the absence of information. In this second approach, a new framework have to be developed: from the syntax to the semantics, ... -
Lexicon-based sentiment analysis in texts using Formal Concept Analysis.
Ojeda Hernández, Manuel; López-Rodríguez, Domingo; Mora-Bonilla, Ángel
(Elsevier, 2023-02-03)
In this paper, we present a novel approach for sentiment analysis that uses Formal Concept Analysis (FCA) to create dictionaries for classification. Unlike other methods that rely on pre-defined lexicons, our approach ... -
