Un portail sémantique pour la gestion des connaissances en cancérologie

Abstract : This thesis presents the building of a semantic portal for knowledge management in oncology. OWL is used for representing the knowledge contained in medical decision protocols. The inferences associated with OWL are applied to decision support for protocol application. But the knowledge contained in the protocols don't take into account all the possible situations and needs to be adapted for particular cases. We propose an extension of OWL in order to allow the representation of adaptation knowledge and to implement a case-based reasoning (CBR) mechanism integrated to the semantic Web infrastructure. Furthermore, in complex domains like oncology, there exist multiple viewpoints on the knowledge. We use the C-OWL language to establish a multiple viewpoint representation of the protocols. On this basis, a decentralized CBR mechanism is defined. It exploits the viewpoints to distribute CBR in several processes. The relations existing between viewpoints are then used for collaboration between these processes. Multiple viewpoint representation has shown contributions concerning knowledge engineering, the building of the CBR mechanism and the scalability of reasoning mechanisms for the semantic Web.
