The evolution of mobile technologies, like web-enable cellphones, PDAs and wireless networks, makes it now possible to use these technologies for collaborative work through web-based groupware systems. However, due to the limitations of these technologies, some adaptation is essential in these systems. In order to adapt their behaviour to the user's(More)
— Despite its growing acceptance, Service-Oriented Computing (SOC) remains a computing mechanism to speed-up the design of software applications by assembling ready-made software services. We argue that it is difficult for business people to fully benefit of SOC if it remains at the software level. The paper proposes a move towards a description of services(More)

Awareness support is an important feature for groupware systems. It provides a context for individuals contributions, improving those contributions and avoiding contradictory interactions among(More)
Context-aware systems are applications that adapt themselves to several situations involving user, network, data, hardware and the application itself. In this paper, we review several context models proposed in different domains: content adaptation, service adaptation, information retrieval, etc. The purpose of this review is to expose the representation of(More)

The efficiency of this mechanism mainly depends on the method(s) used to draw inferences based on existing evidence and(More)
