Characterization of database dependencies with FCA and pattern structures
Baixeries i Juvillà, Jaume; Kaytoue, Mehdi; Napoli, Amedeo (Springer International Publishing, 2014-04-12)
Capítol de llibre
Accés restringit per política de l'editorialIn this review paper, we present some recent results on the characterization of Functional Dependencies and variations with the formalism of Pattern Structures and Formal Concept Analysis. Although these dependencies ... -
Characterization of order-like dependencies with formal concept analysis
Codocedo, Victor; Baixeries i Juvillà, Jaume; Kaytoue, Mehdi; Napoli, Amedeo (2011)
Text en actes de congrés
Accés obertFunctional Dependencies (FDs) play a key role in many fields of the relational database model, one of the most widely used database systems. FDs have also been applied in data analysis, data quality, knowl- edge discovery ... -

Characterizing approximate-matching dependencies in formal concept analysis with pattern structures
Baixeries i Juvillà, Jaume; Codocedo, Victor; Kaytoue, Mehdi; Napoli, Amedeo (2018-04-26)
Article
Accés obertFunctional dependencies (FDs) provide valuable knowledge on the relations between attributes of a data table. A functional dependency holds when the values of an attribute can be determined by another. It has been shown ... -
Characterizing covers of functional dependencies using FCA
Codocedo, Victor; Baixeries i Juvillà, Jaume; Kaytoue, Mehdi; Napoli, Amedeo (2018)
Text en actes de congrés
Accés obertFunctional dependencies (FDs) can be used for various important operations on data, for instance, checking the consistency and the quality of a database (including databases that contain complex data). Consequently, a ... -
Characterizing functional dependencies in formal concept analysis with pattern structures
Baixeries i Juvillà, Jaume; Kaytoue, Mehdi; Napoli, Amedeo (2014-01-29)
Article
Accés restringit per política de l'editorialComputing functional dependencies from a relation is an important database topic, with many applications in database management, reverse engineering and query optimization. Whereas it has been deeply investigated in those ... -
Computing Functional Dependencies with Pattern Structures
Baixeries i Juvillà, Jaume; Kaytoue, Mehdi; Napoli, Amedeo (2012)
Text en actes de congrés
Accés obertThe treatment of many-valued data with FCA has been achieved by means of scaling. This method has some drawbacks, since the size of the resulting formal contexts depends usually on the number of di erent values that are ... -

Pattern Structures and Concept Lattices for Data Mining and Knowledge Processing
Kaytoue, Mehdi; Codocedo, Victor; Aleksey, Buzmakov; Baixeries i Juvillà, Jaume (Springer International Publishing, 2015)
Text en actes de congrés
Accés obertThis article aims at presenting recent advances in Formal Concept Analysis (2010-2015), especially when the question is dealing with complex data (numbers, graphs, sequences, etc.) in domains such as databases (functional ...
