Context-aware systems acquire and integrate multi-faceted knowledge about their environments in order to make decisions. A number of attempts to build frameworks for context-aware systems have been made, but these have not provided adequate support for context-aware access control. In this paper, we present a framework for context-aware access control and its prototype implementation. The frame...

Being context-ware will improve how software adapts to dynamic changes influenced by various factors during the operation of the software. Context-aware techniques have been widely applied in different types of applications, but still are limited to small scale or single-organizational environments due to the lack of well-agreed interfaces, protocols, and models for exchanging context data. Web...

This paper presents a framework for building user interfaces for context-aware service management. It enables us to easily deploy context-aware services at computers through user-friendly manipulations to edit documents and monitor changes and services in the real world. It is constructed as a compound document framework whose the structural composition of visual components can be adapted to ch...

For surviving in their complex and dynamic environments, organisations should be adaptable and interoperable with these environments. Stakeholders’ expectations change unpredictably and are often dependent on the contextual information. A context sensitive BP model is able to adapt the execution of the instances to the changing contexts and then to the stakeholders’ requirements. Our objective ...

Context-awareness has emerged as a new perspective for business process modelling. Even though some works have studied it, many challenges have not been addressed yet. There is a clear need for approaches that (i) facilitate the identification of the context properties that influence a business process and (ii) provide guidance for correct modelling of contextualised business processes. This pa...

Context-aware applications behave differently depending on the context in which they are running. Since context-specific behaviour tends to crosscut base programs, it can advantageously be implemented as aspects. This leads to the notion of context-aware aspects, i.e., aspects whose behaviour depends on context. This paper analyzes the issue of appropriate support from the aspect language to bo...

Nowadays, numerous journals and conferences have published articles related to context-aware systems, indicating many researchers’ interest. Therefore, the goal of this paper is to review the works that were published in journals, suggest a new classification framework of context-aware systems, and explore each feature of classification framework. This paper is based on a literature review of c...

Ubiquitous computing applications must have access to context information to provide context-aware services. The literature reports on applications that process and store context information as part of their functionality and also on reusable infrastructures dedicated to capturing, storing and processing context information. We advocate that infrastructures aimed at supporting context-aware app...

The immaturity of the field of context-aware computing means that little is known about how to incorporate appropriate personalisation mechanisms into context-aware applications. One of the main challenges is how to elicit and represent complex, context-dependent requirements, and then use the resulting representations within context-aware applications to support decision-making processes. In t...

♣ [email protected] ABSTRACT The understanding of context and context-awareness is very important for the areas of handheld and ubiquitous computing. Unfortunately, at present, there has not been a satisfactory definition of these two concepts that would lead to a more effective communication in humancomputer interaction. As a result, on the one hand, application designers are not abl...
