Domain and Competences Ontologies and Their Maintenance for an Intelligent Dissemination of Documents

One of the big challenges of the knowledge management is the active and intelligent dissemination of the know-how to users while executing their tasks, without bothering them with information that is too far from their competences or out of their interest fields. Delivering a new document to the concerned users consists basically on appreciating the semantic relevance of the content of this document (domain ontology) in relation with users’ competences (competences ontology). In this paper, we illustrate the importance, within a documentary dissemination service, of the integration of an ontologies system, essentially based on the domain and the competences, but also on the users, the documents, the processes and the enterprise. The maintenance of these ontologies and basically those related to documents, to domain and to competences is a crucial aspect for the system survival. So, we describe what role the texts analysis can play for the maintenance of these ontologies.
