Interrogation de données multimédia fondée sur les connaissances du domaine

In this paper, we present a domain knowledge based approach to retrieve multimedia data described by using the MPEG-7 standard. This standard is used since it provides tools to represent, in the same description, the structural and semantic aspects of the multimedia content. However, due to its XML schema based definition, MPEG-7 lacks ability to describe implicit information and to integrate d...

Thèse de doctorat DOMAINE : STIC Spécialité : Traitement du Signal

This thesis addresses the challenges encountered when dealing with signal decomposition problems with an unknown number of components in a Bayesian framework. Particularly, we focus on the issue of summarizing the variable-dimensional posterior distributions that typically arise in such problems. Such posterior distributions are defined over union of subspaces of differing dimensionality, and c...

EXIT : Un système itératif pour l’extraction de la terminologie du domaine à partir de corpus spécialisés

The work presented in this paper is relative to the discovery of a significant terminology in specialized texts. Our approach, partly based on statistical methods extracts the terms in an iterative way. At first, the only terms looked for are binary. The binary terms detected during this first phase are included in the corpus, and the process is iteratively repeated in order to detect very long...
