Twitter et la linguistique située: Réflexions méthodologiques à partir de l’exemple de tweets sur la métropole de Dijon

2020

International audience; Cette communication s’inscrit dans le cadre du projet de recherche interdisciplinaire POPSU visant à entre autres à analyser l’identité métropolitaine et identifier les intérêts des citoyens. Pour alimenter la discussion proposée, nous exploiterons un corpus original de 300 000 tweets collectés en temps réel depuis juillet 2019 dans le cadre du projet interdisciplinaire POPSU Dijon, hébergé à la MSH Dijon et dont le but est d’explorer les interactions des utilisateurs de Twitter lorsqu’ils parlent de Dijon et de la métropole. Nous commencerons par discuter les aspects liés à la collecte de données Twitter :- juridiques : protections des données personnelles, Open Dat…

Constraint Management in Engineering of Complex Information Systems

2009

We propose to build an engineering environment for information systems by using metamodels, OCL and symbolic model checkers to manage  constraints. Our proposal is based on a definition of constraints as 3D spaces with  dimensions corresponding to UML diagrams, constructs, and abstraction levels. We show how such environments can help with engineering quality complex systems by allowing to lift up a part of constraint verifications.

Domain knowledge integration and semantical quality management -A biology case study

2008

International audience; The management of semantical quality is a major challenge in the context of knowledge integration. In this paper, we describe a new approach to constraint management that emphasizes constraint traceability when moving from the semantical level to the operational one.Our strategy for management of semantical quality is related to a metamo-deling-based approach to knowledge integration. We carry out knowledge integration “on the fly” by using transformations applied to models belonging to our metamodeling architecture. The resulting integrated models access available resources through web services whose input and output parameters are guarded by constraints. Integrated…
