The focus is on candidates’ Twitter usage during the 2014 EU elections in France and in Germany. Quantitative and qualitative analyses of tweets collected during a period of four weeks have been carried out on the basis of the functional operator model of Twitter. The model serves as a framework for assessing users’ tweeting styles, which can range between personal-interactive and topical-informative. The comparison of French and German top candidates’ tweeting styles, which mainly appear to be „personal-interactive“, however questions the candidates’ alleged efforts to enter into dialogue with their voters.

Nous decrivons un cadre de travail pour les systemes d'information cooperatifs et presentons le projet DECA qui propose une approche de mediation de contextes. La principale caracteristique de la solution proposee reside dans la resolution dynamique des conflits schematiques et semantiques des donnees. Ceci est realise a travers le modele AM UN, modele oriente objet etendu pour gerer la cooperation de systemes. Une architecture faiblement couplee, basee sur le paradigme multi-agents, est presentee.

Archaeological data include textual information, measures, sketches, photographies, 3D models, and a vast amount of links between data and historical information sources. We develop a formal model for ontology-based annotations that conforms to a semi-ring algebraic structure and we define a subset of algebraic operators to query annotations. We show how our approach is instantiated in a collaborative Web platform for the Burgundy Stone project.
