Elaboration d'entrepôts de données complexes

In this paper, we study the data warehouse modelling used in decision support systems. We provide an objectoriented data warehouse model allowing data warehouse description as a central repository of relevant, complex and temporal data. Our model integrates three concepts such as warehouse object, environment and warehouse class. Each warehouse object is composed of one current state, several p...

Elaboration de fonctions de croyance à partir de données GPS et SIG. Etude de stratégies de fusion pour la localisation

RÉSUMÉ. Positionner un véhicule automobile sur une carte numérique est une fonction essentielle pour utiliser les informations contenues dans la base de données par l'intermédiaire d'un Système d'Information Géographique (SIG). Si on utilise un récepteur GPS (Global Positioning System), la mise en correspondance de ses mesures avec les données du réseau routier de la base est une étape préalabl...

Elaboration on Elaboration: Event Coreference

This paper discusses and clariies the elaboration discourse relation using the notion of event coreference. Unlike entity coreference, event coreference has rarely been studied in detail, except for (pro)nominals referring to an event. Here the focus will be on event coreference between two sentences (in an elaboration relation). This study will put forward unusual linguistic phenomena, e.g. co...

Circumstance Elaboration Joint Joint Example Elaboration Elaboration Condition Circumstance

Researchers in discourse have long hypothesized that the nuclei of a rhetorical structure tree provide a good summary of the text for which that tree was built. In this paper, I discuss a psy-cholinguistic experiment that validates this hypothesis , but that also shows that the distinction between nuclei and satellites is not suucient if we want to build summaries of very high quality. I empiri...
