Cette recherche s’inscrit dans le domaine de la personnalisation d’Entrep\u00f4t de Donn\u00e9es (ED) et concerne l’aide \u00e0 l’exploitation d’un ED. Nous int\u00e9ressons \u00e0 l’assistance \u00e0 apporter \u00e0 un utilisateur lors d’une analyse en ligne, dans son utilisation de ressources d’exploitation existantes. Le domaine d’application concern\u00e9 est la gestion hospitali\u00e8re, dans le cadre de la nouvelle gouvernance, et en se limitant au p\u00e9rim\u00e8tre du Programme de M\u00e9dicalisation des Syst\u00e8mes d’Information (PMSI). Cette recherche a \u00e9t\u00e9 support\u00e9e par l’Assistance Publique des H\u00f4pitaux de Marseille (APHM). L’approche retenue pour d\u00e9velopper une telle assistance \u00e0 l’utilisateur d’ED est s\u00e9mantique et guid\u00e9e par l’usage d’ontologies. Le syst\u00e8me d’assistance mettant en oeuvre cette approche, nomm\u00e9 Ontologies-based Personalization System (OPS), s’appuie sur une Base de Connaissances (BC) exploit\u00e9e par un moteur de personnalisation. La BC est compos\u00e9e des trois ontologies : de domaine, de l’ED et des ressources. Le moteur de personnalisation permet d’une part une recherche personnalis\u00e9e de ressources d’exploitation de l’ED en s’appuyant sur le profil de l’utilisateur, et d’autre part pour une ressource particuli\u00e8re, une recommandation de ressources compl\u00e9mentaires selon trois strat\u00e9gies possibles. Afin de valider nos propositions, un prototype du syst\u00e8me OPS a \u00e9t\u00e9 d\u00e9velopp\u00e9 avec un moteur de personnalisation a \u00e9t\u00e9 impl\u00e9ment\u00e9 en Java et exploitant une base de connaissance constitu\u00e9e des trois ontologies en OWL interconnect\u00e9es. Nous illustrons le fonctionnement de notre syst\u00e8me sur trois scenarii d’exp\u00e9rimentation li\u00e9s au PMSI et d\u00e9finis avec des experts m\u00e9tiers de l’APHM.<\/span><\/p>\n

Abstract<\/em><\/strong><\/span><\/p>\n

This research is situated in the domain of Data Warehouses (DW) personalization and concerns DW assistance. Specifically, we are interested in assisting a user during an online analysis processes to use existing operational resources. The application of this research concerns hospital management, for hospitals governance, and is limited to the scope of the Program of Medicalization of Information Systems (PMSI). This research was supported by the Public Hospitals of Marseille (APHM). Our proposal is a semantic approach based on ontologies. The support system implementing this approach, called Ontology-based Personalization System (OPS), is based on a knowledge base operated by a personalization engine. The knowledge base is composed of three ontologies: a domain ontology, an ontology of the DW structure, and an ontology of resources. The personalization engine allows firstly, a personalized search of resources of the DW based on users profile, and secondly for a particular resource, an expansion of the research by recommending new resources based on the context of the resource. To recommend new resources, we have proposed three possible strategies. To validate our proposal, a prototype of the OPS system was developed, a personalization engine has been implemented in Java. This engine exploit an OWL knowledge composed of three interconnected OWL ontologies. We illustrate three experimental scenarios related to PMSI and defined with APHM domain experts.\"\"<\/span><\/em><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
