Structuring Probabilistic Data by Galois Lattices

چکیده
RÉSUMÉ – Organisation de données probabilistes par des treillis de Galois Dans cet article, nous nous intéressons à l’organisation de données probabilistes par des treillis de Galois. Deux correspondances de Galois sont établies, en définissant de façon appropriée les opérateurs de généralisation et d'extension. Ces correspondances permettent de construire deux treillis, appelés treillis de l’union et treillis de l’intersection, correspondant à ces deux correspondances de Galois. Un nouvel algorithme de construction de treillis est proposé. Deux exemples sur des données réelles illustrent l’approche présentée. MOTS-CLÉS – Treillis de Galois, Données probabilistes, Classification conceptuelle

Using Galois Lattices to Represent Network Data
Galois lattices are introduced as a device to provide a general representation for two mode social network data. It is shown that Galois lattices yield a single visual image of such data in cases where most alternative models produce dual images. The inzage provided by the Galois lattice produces, moreover, an inzage that can suggest useful insights about the structuralproperties of the data. A...
متن کاملTowards Knowledge Management using Galois Lattices ∗
In this paper we investigate the application of Galois (or concept) lattices on different information or data sources (e.g. web documents or bibliographical items) in order to organise knowledge that can be extracted from the data. This knowledge organisation can then be used for a number of purposes, e.g. knowledge management in an organisation, document retrieval on the Web, etc. Galois latti...
متن کاملMaximal and Stochastic Galois Lattices
We present a general formula for the intent–extent mappings of a Galois lattice generated by individual descriptions which lie in any arbitrary lattice. The formulation is unique if a natural maximality condition is required. This formulation yields, as particular cases, formal concept binary Galois lattices of Wille, those de0ned by Brito or Blyth–Janowitz, as well as fuzzy or stochastic Galoi...
متن کاملLattices for 3-Dimensional Fuzzy Data generated by Fuzzy Galois Connections
Vagueness and high dimensional space data are usual features of current data. The paper is an approach to identify conceptual structures among fuzzy three dimensional data sets in order to get conceptual hierarchy. We propose a fuzzy extension of the Galois connections that allows to demonstrate an isomorphism theorem between fuzzy sets closures which is the basis for generating lattices ordere...
