Structuration Conceptuelle et Physique de l'Espace des Objets dans un Système de Gestion des Données et des Connaissances

Knowledge Base Management Systems are not designed to manage large amounts of data in an efficient manner, contrary to DBMS of which it is the primary purpose. We present an approach that unifies KBMS and DBMS, by providing an efficient management of wide volumes of (shared) data and reasoning capabilities (instance classification). We propose a conceptual structuring of the object space that r...

Dynamiques globales et locales dans un réseau de télécommunications

Traditional network generation models attempt to replicate global structural properties (degree distribution, average distance, clustering coefficient, communities, etc.) through synthetic link formation mechanisms such as triadic closure or preferential attachment. In this work, we study the evolution of a very big communication network coming from mobile telephony and we analyse the link form...

Un modèle booléen pour l'énumération des siphons et des pièges minimaux dans les réseaux de Petri

Petri-nets are a simple formalism for modeling concurrent computation. Recently, they have emerged as a powerful tool for the modeling and analysis of biochemical reaction networks, bridging the gap between purely qualitative and quantitative models. These networks can be large and complex, which makes their study difficult and computationally challenging. In this paper, we focus on two structu...
