De la recherche sociale d'information à la recherche collaborative d'information
In this paper, we explain social information retrieval (SIR) and collaborative information retrieval (CIR). We see SIR as a way of knowing who to collaborate with in resolving an information problem while CIR entails the process of mutual understanding and solving of an information problem among collaborators. We are interested in the transition from SIR to CIR hence we developed a communicatio...
متن کاملVers l'intégration des métarôles pour la recherche d'information collaborative
Several work have highlighted the benefit of collaboration for solving complex or exploratory search tasks, impacting information retrieval models towards a multi-user setting. In this context, three main paradigms have been highlighted (e.g. the division of labor relying on task-oriented roles) in order to structure the search session and optimize its effectiveness. In this paper, we propose t...
متن کاملDéfinition et exploitation des méta-rôles des utilisateurs pour la recherche d'information collaborative
Collaborative information retrieval is a particular setting involving a set of users sharing the same information need. In this context, the application of the division of labor policy through collaborators’ roles is generally used in order to structure the search session and enhance its retrieval effectiveness.

متن کاملRapport De Recherche
In this paper we present a novel approach for mimicking expressions in 3D from a monocular video sequence. To this end, first we construct a high resolution semantic mesh model through automatic global and local registration of a low resolution range data. The MPEG-4 standard and radial basis functions are then considered to represent and animate such a model using a predefined set of control p...
