Approach for Capitalization knowledge in the context of S-maintenance platform

Knowledge management (KM) is a familiar concept to specialists in information and documentation. Tacit knowledge and explicit knowledge are often communicated with difficulty acquired by experience or learning. In industrial systems and precisely in a maintenance system, it has a wealth of knowledge often poorly exploited especially during the execution of the maintenance process also the establishment of a network or intranet or document circulation system which poses problems of integration and data exchange. As a model to express the semantic data, ontologies are one of the solutions to these relevant problems. The aim is to propose an approach to capitalize the knowledge; it is based on capitalization, especially the skills of experts. We propose in this paper to present in the first place, the effectiveness of the capitalization of knowledge in the field of maintenance. Then we propose an approach to build a knowledge base based on ontology.
