1	Relations entre bases de données et ontologies dans le cadre du web des données Curé, Olivier 11 October 2010 (has links) (PDF) Ce manuscrit présente mon intérêt pour la conception des méthodes et algorithmes nécessaires pour la réalisation d'applications avancées pour le web sémantique. Cette extension du web actuel vise à autoriser l'intégration et le partage de données entre organismes et applications. Une conséquence directe du succès de cette approche permettrait de considérer le web comme une base de données globale contenant les données stockées sur toutes les machines connectées. Cet aspect s'exprime bien dans le site web dédié à l'activité web sémantique du W3C, qui déclare que le web sémantique est un web des données. Ainsi, ce web des données permettra de soumettre des requêtes structurées sur tous les ensembles de données connectés, et de récupérer des résultats pertinents provenant de sources diverses et hétérogènes. Une question essentielle liée à cette hétérogénéité concerne la notion de sémantique. Dans le contexte du web sémantique, elle est généralement traitée avec des ontologies et les opérations de médiation associées. Ma recherche s'ancrent dans ces thématiques et ce manuscrit vise à présenter quelques unes de mes recherches et résultats, ainsi qu'à décrire certaines des applications que j'ai conçues et implémentées base de données DBOM médiation d'ontologies
2	A review of the impact of Canadian law, policy and P3 practice on the case for procuring capital-intensive infrastructure services via P3s Jatto, Lucky Bryce Junior 02 September 2011 (has links) This dissertation investigates the advantages of procuring capital-intensive infrastructure services via Public-Private Partnerships (P3s or PPPs) – cost and time savings and; innovation and high levels of efficiency – accounting for these advantages by reference to the underlying legal provisions and principles that facilitate them; and in this process highlights two significant directions in which Canadian P3 law, policy and practice has evolved – the enactment of P3 legislation and/or the formulation of non-statutory P3-related policy; as well as the establishment of legal institutions that promote and/or facilitate P3 procurements. The dissertation also addresses key arguments raised against P3s, by reference to aspects of Canadian law, policy and P3 practice. The research methodology comprises a detailed review of legal and non-legal sources. The implication of the research findings is that, given the foregoing developments in Canadian P3 law, policy and practice, the key arguments canvassed against P3s are overstated and lacking in merit.
