One of the foundations of cooperative work is the exchange of data and especially data that is bound to a file. the usage of tools like e-mail to exchange documents makes it difficult to keep the existing context and metadata linked to the document. A general light-weighted approach and system-architecture will be presented that prevents the loss of document-meta-information and organizes a distributed document-context as an abstract layer that summarizes and structures available metadata. to a coherent unit.

context plays a crucial role when measuring the similarity of two concepts. Nonetheless, the modelling of context has been mostly neglected in existing similarity measurement theories. In this paper, we explore the influence of context in existing similarity measurement approaches for the geospatial domain, focussing on whether and how these approaches account for it. Based on these observations, the processing of context during similarity measurement is analysed, and general implementation issues, especially ease of integration into existing, reasoning systems and computability, are discussed. the results of the different analyses are then combined into a generic set of characteristics of context for similarity measurement, with regard to the geospatial domain.

this paper discusses the dynamic of contextthrough the use of a context-based formalism called contextual graphs that has been initially developed in the SART application for the development of a support system in incident solving on a subway line. First, we present the formalism of contextual graphs through its new implementation. Second, we discuss the dynamic of context in contextual graphs. third, we present two characteristics of contextual graphs as they relate to the dynamic of context, the incremental knowledge acquisition and the explanation generation. We conclude by a discussion of the key properties and the potential of contextual graphs for other applications.

the process we propose in this paper is in keeping with a more general thought about e-learning systems reengineering. It deals more precisely with pedagogical scenario reengineering by assisting designers in the uses tracking definition phase in order to allow them to a posteriori understanding of the learning session sequence. From this point of view, our process presents some advantages. First, it allows the recommendation of uses to track from the designer built scenario structure. then, it proposes a formal way to transcribe these observed uses in a design interpretable language, and thus to compare a priori scenario to the one resulting from a posteriori observed uses. Lastly, it relies on an analysis at a meta-model level of the pedagogical modeling language chosen by designers and, therefore, allows complete dissociation from a chosen language.

Autonomic computing is a very ambitious domain dealing with issues such as system self-management, proactive services and adaptation to unpredicted situations. the development of ubiquitous computing have shown also the importance of adapting the services to their context. In general, a service cannot adapt autonomously to its context beyond the limits fixed a priori by its developer. In order to overcome this limitation, we propose a dynamically updatable service-context model (knowledge representation) that enables an adaptation platform to diagnose the service adequacy to context and automatically search for solutions in order to correct the inadequacy.

In e-commerce applications, no systematic research has been provided to evaluate if the use of a detailed and rich contextual representation improves the user modeling predictive performances. An underestimated issue is also evaluating if context could be inferred by existing customer data off-line, in spite of getting the customer involved on-line in the gathering process. In this paper, we address those problems, defining context as "the intent of" a customer purchase. To this aim, we collected data containing rich contextual information, hierarchically structured, by developing a special-purpose browser. the experimental results show that the finer the granularity of contextual information the better is the modeling of customers' behavior. Representing the context in a hierarchical structure is a necessary condition, for inferring the context off-line, but it's not a sufficient one.

In the Design-Based Research (DBR) methodology, the process is as important as the product, and each iteration is considered a sub-result leading to the next one. this methodology is being used in the TEEC project, to both study and elaborate solutions for Learning in context. this paper describes the origins of the project, as well as the steps taken to conduct it, with a perspective for future work. the DBR methodology is presented as applied in the TEEC project (TEEC = Technologies Educatives et Enseignement en contexte).

Ambient intelligent systems are context aware by perceiving and reasoning about their environment, they perceive the needs of their users and proactively respond to these needs by being context sensitive. Users do not interact withthese systems by traditional means only, but also through behavioural interfaces. this combination of mixed initiative systems and unconventional interfaces puts strong requirements on the explanatory capabilities of any system. the work presented here focuses on explaining the behaviour of an ambient intelligent systems to its users. It demonstrates how explanations can be combined withcontext to deal withthe different types of explanations that are required for a meaningful interaction of a system and its users.
