Recommandation et analyse de sentiments dans un espace latent textuel

Recommender systems were developed to cherry-pick interesting content in an always growing environment to help users discover new products or information that they might like. Traditional collaborative filtering methods mainly focus on the ratings to establish user profiles, ignoring the joint review text. Our work does the opposite. We use the written comments as the primary source of informat...

Complexité en espace de l'exploration de graphes

Graph Exploration is a problem motivated by several aspects of theoretical computer science, including logic and computational complexity. It has also numerous applications in robotics. In all these contexts, the amount of memory used by the mobile entity (robot, finite automaton, etc.) performing exploration is a key parameter. In this thesis, we study in depth the space complexity of graph ex...

Espace de Services : Vers une formalisation des Systèmes d'Information Pervasifs

Pervasive Information Systems (PIS) represent the next generation of Information Systems (IS). They differ from both traditional IS and pervasive systems: from the former by the heterogeneity of the pervasive environment to which they belong, and from the latter, by the fact that they must integrate an organization and its strategies. In this paper, we propose a conceptual framework, called ser...
