Structures latticielles, correspondances de Galois contraintes et classification symbolique

This thesis is in the field of the latticial analysis of data in the situation, very general, whereobjects of various nature are described by variables of various types ; one makes simply theassumption (realistic) according to which each variable takes his values in a lattice. The problemsof processing of such data (extraction of knowledge) often amount seeking to obtain Moore<l...

Découverte automatique de correspondances entre ontologies

In this thesis, we investigate a principled approach for defining and discovering probabilistic inclusion mappings between two taxonomies, with a clear semantic, in a purpose of collaborative exchange of documents. Firstly, we compare two ways of modeling probabilistic mappings which are compatible with the logical constraints declared in each taxonomy according to a monotony property, then we ...

ECrits - Visualizing Support Ticket Escalation Risk

Managing support tickets in large, multi-product organizations is difficult. Failure to meet the expectations of customers can lead to the escalation of support tickets, which is costly for IBM in terms of customer relationships and resources spent addressing the escalation. Keeping the customer happy is an important task in requirements engineering, which often comes in the form of handling th...

M ar 1 99 4 On mean field glassy dynamics out of equilibrium Silvio Franz and Marc Mézard

We study the off equilibrium dynamics of a mean field disordered systems which can be interpreted both as a long range interaction spin glass and as a particle in a random potential. The statics of this problem is well known and exhibits a low temperature spin glass phase with continuous replica symmetry breaking. We study the equations of off equilibrium dynamics with analytical and numerical ...
