Nowadays, with the great diffusion of mobile technology, and ubiquitous systems, the context has become the ear and the eye of Information Systems. These systems are more and more based on the usage of Web Services which are designed to support interoperable application-to-application interaction over the Web. In this article, we present our contribution aims at proposing a new architecture of Web Information Systems, supporting the adaptation process to the user context and returning to the user a list of Web Services adapted to his context. This architecture is based on an extension of AHA! architecture adding an adaptation layer containing various components dedicated to the context adaptation. So, our aim is to build an Adaptive Web Information System based on Web Services. Finally, we present an algorithm which we use to build a user contextual profile "Profile-Context-User (UCP)" containing only the user preference that can be satisfied with the context.

“…P2P systems have the potential to facilitate smooth transitions from synchronous to asynchronous collaboration modes by notifying group members of opportunities for collaboration, promoting social contacts among peers, and fostering a sense of community within peergroups. P2P systems are also pervasive and ubiquitous in nature, thus enabling contextualised awareness [10], [16] to be provided to group members.…”

Monitoring and awareness are essential in collaborative work environments, in order to support team members' interaction and coordination processes. There has been much work in implementing awareness in web-based applications, but less so for P2P collaborative systems. P2P systems have the potential to foster more group interaction than server-based approaches, as group members can interact directly with each other and can share their knowledge, skills and resources in order to provide mutual support in the accomplishment of group tasks. Several challenges arise due to the large-scale, dynamic and heterogenous nature of P2P collaborative systems. In this paper we discuss the provision of event-based awareness services in P2P groupware systems. We first review the major requirements for such awareness functionality, and propose a structured P2P network model for meeting these requirements. We then identify a set of low level awareness services and show how these can interoperate over the P2P network in order to provide awareness as part of the P2P middleware infrastructure. Finally, we envision the use of service composition to provide more complex awareness services and we discuss the implementation of a superpeer network on a Cloud platform and the provision of reliable awareness services from the Cloud.

“…Par conséquent, ces systèmes deviennent difficiles à concevoir, et les composants liés à la détection et à la manipulation du contexte ne sont pas (ou sont très peu) réutilisables dans d'autres systèmes. Par exemple, l'étude de l'application Campus Aware [5] ou de l'architecture MoCA [16], nous permet de noter l'inexistence d'une représentation propre et dédiée au contexte. Dès lors, en l'absence d'une formalisation de la notion de contexte, l'introduction et l'exploitation dans ces systèmes d'une information contextuelle, autre que la localisation, comme, par exemple, les activités de l'utilisateur, ne peuvent se faire facilement, ni reposer sur la réutilisation de composants préexistants.…”

RESUMEDans cet article, nous présentons un modèle de représentation objet du contexte d'un utilisateur nomade dans un collecticiel sur le Web. En raison de l'évolution de l'informatique nomade, ces systèmes tendent de plus en plus à devenir « sensibles au contexte » et ainsi à adapter leur comportement au contexte de l'utilisateur afin de mieux le satisfaire. Le modèle de contexte proposé ici inclut les aspects physiques (la localisation ou le dispositif utilisé) mais également les aspects liés au processus coopératif dans lequel l'utilisateur est impliqué (groupe, rôle, activités, etc.). Cette formalisation de la notion de contexte permet la séparation entre les informations relatives au contexte et celles propres au système, facilitant ainsi la conception des systèmes collaboratifs, traditionnellement complexes. Le modèle de contexte proposé permet au système d'adapter l'information de conscience de groupe destinée à chaque membre participant à une tâche collective par une reconnaissance des circonstances dans lesquelles il accède au système. ABSTRACTIn this paper, we propose an object oriented model for describing a mobile user's context inside a Web-based groupware system. These systems are confronted to the growing use of mobile devices, such as laptops, PDAs or cellular phones, which requires special context-aware capabilities. Our model formalizes the context notion, decoupling context and system information, which consequently reduces the system development complexity. We consider the context as a set of basic elements that identify the circumstances in which the user is accessing the system. These elements include elements related to physical aspects (the user's location and device), as well as those related to the cooperative process in which the user is involved (group, role, activities, etc.). Mot-clésInformatique nomade, informatique sensible au contexte, travail coopératif assisté par ordinateur.
