La discipline, dimension oubliée de l’action en contexte extrême ?

Contrats de contexte pour la gestion de contexte répartie

In ambient computing environments, applications need to monitor their execution context and react to changes in their environment. The distribution of context data poses great challenges to researchers. In this paper, we focus in the modeling of the distribution of context data. A model of the distribution of context data allows the expression of context constraints and the delivery of unambigu...

La recherche d'information. De la documentation automatique à la recherche d'information en contexte

Information Retrieval (IR) was founded soon after the construction of the first computers and, as such, is certainly the oldest application of computer science to the problem of accessing digitalized documents. About sixty years later and twenty years after the Internet revolution and its billions of pages on the Web IR is even more in the air. The domain was for a long time restricted to non i...

Modélisation de HMM en contexte avec des arbres de décision pour la reconnaissance de mots manuscrits

This paper presents an HMM-based recognizer for the off-line recognition of handwritten words. Word models are the concatenation of context-dependent character models: the trigraphs. Due to the large number of possible context-dependent models to compute, a clustering is applied on each state position, based on decision trees. Our system is shown to perform better than a baseline context indepe...
