Méthodologie de construction des ontologies pour la résolution de conflits des systèmes d'information

The information system (IS) modelling requires a perfect knowledge of the concerned field and a good study of user’s requirements. This task becomes very difficult because the complexity of the current applications in particular using new technologies (elearning, E-trade, data warehouse...) and the enormous mass of concepts coming from heterogeneous sources. These problems can generate various types of conflicts (syntactic, semantic and structural), we propose the ontology using to assist the designers during their task of modelling for a given field. In this paper, we propose an ontology building methodology to resolve their IS conflicts.
