Enterprise ontology oriented competence: A support for enterprise architecture

The urbanization of information system (U.I.S) is a fairly complex process because like all EA approaches around the world, it is based on a layered representation. In the context of modeling the EA layer is a point of view as a strategic, business, technical point of view etc. In addition, the information system (I.S) is not just a technical challenge, focused on information and IT support systems. On the contrary, everything indicates that the key issues within the organization and the human factor in business as well as their competence. So taking into account the changes in the organization is critical to the success of urbanization projects. Thus, organization models have been developed in the context of enterprise architecture (EA). These models aim to structure a holistic view of the enterprise. However, a semantic deficit was identified by several researches in these models. So, several studies have investigated to solve this problem by proposing ontologies as a semantic enrichment tool. Based on these works we built an ontology that aims to support the process of change in an UIS approach. Thus we present in this paper a first part summarizes the different ontologies developed for the company and in the second part we present a modular ontology oriented competence exploitable in the context of UISI. Then in the end we present the technical way to use this ontology.
