Access to organizational knowledge : ontologies’ network based approach

The widespread use of computer technology has led organizations to store their data and knowledge in databases, documents, forms, spreadsheets ... What led to constitute an increasingly vast set of heterogeneous resources. Consequently, it has become increasingly difficult and humanly unfeasible to have a global vision of what the organization "knows". Our approach focuses on the explicit knowledge and employs semantic web technologies to address the problem of heterogeneity of resources, it aims to build a knowledge map as a network of ontologies connected to the organization's resources . We study the case of GSEM in order to validate our approach.
