Validation of an ontology of risk and disaster through a case study of the 1923 Great Kanto Earthquake
2009
International audience; This paper seeks to validate a factual ontologyderived from an ontology of the domain of risk and catastrophe (Provitolo, Müller, Dubos-Paillard, 2009). The factual ontology is that part describing the structure and dynamics of the system, that is, the representation of an event and of on what it has a bearing. The objective is to show that the ontology is able to account for and allow comparison between complex stories (because of the diversity of event types and of their multi-scale description). The event used as the basis for validation of the ontology is the Great Kanto Earthquake of 1923. The account is that of P. Hadfield (1991) that provides a detailed descri…
Dynamic composition of services : application to designing and developping information systems in a distributed environment
2010
The service oriented computing paradigm plays an increasingly important role in structuring complex systems. Application design and development approaches are witnessing a shift from traditional models towards a more dynamic service oriented model promoting reuse and adaptability. In this thesis, we study an approach for application design and development based on services’ composition. We propose DyCoSe, an environment for sharing services. It consists of an enterprise ecosystem wherein members, organized in communities, share a global agreement describing traditional business functionalities and common non-functional properties. DyCoSe relies on a three level architecture for service base…
