Relations sémantiques pour l'ingénierie documentaire

The growing part of the New Technologies of Information and Communication (NTIC) comes along with the passage on numeric support of many documentary capitals. So, we attend gradually the digitalization of working documents of all kinds: medical files, educational files, technical documentations, etc. But how make sure that this change of paradigm benefits the readers and the authors of documents? On this matter, we are interested in the modeling and in the exploitation of numeric documents by guaranteeing an added value to the numeric version with regard to its paper homologue: added value for the reader, who has to have semantic tools to navigate more effectively towards what interests him according to his task of reading; added value for the author, who must be able to control his productions, produce new resources by re-use and be assured of an effective management of the evolution of his productions. We present here how we use the ontological approach, the semantic relation concept ant the object-oriented approach to answer these expectations. MOTS-CLES : document numérique, ontologie, relation sémantique, structure de document, approche orientée objet.
