OCEAN: A Semantic Web Service to Extract Knowledge in E-Groupwares

Some research programs are focused on the use of web services and semantic web approach to design tools for knowledge management. These tools help to share information among business applications. We will prove in this paper the benefit to combine semantic and web services approaches to identify and annotate knowledge in a heterogeneous and distributed information landscape. We present here, a comprehensive explanation of our approach which integrates an intelligent reuse module of knowledge that allows engineers to capitalize their know-how. This knowledge will be extracted by web services that enable communication between several business applications. Then in the second section, we describe different ontologies which are created by users depending on their needs to define knowledge. These are extracted from business applications thanks to semantic web service. At the end, this knowledge will be annotated and saved in a RDF file.
