This double approach aims at showing that if the implicit structure of dictionaries, mathematically identified, is adequate with the way young children categorise, th...

Modélisation des métadonnées pour une recomposition dynamique des documents

This paper presents a solution to cope with document management problems.

The novelty consists of reasoning on authorisation dependently on task delegation events, and specifies them...
