Due to the popularity of context-aware computingand the rapid growth of the smart phone devices, modeling anindividual's phone call response behavior may assist them intheir daily activities for managing call interruptions. A key stepof such modeling is to discovering call response behavioral rulesbased on multi-dimensional contexts related to individual'sbehavior. Currently, researchers use classification...
With the convergence of pervasive mobile computing and social networking, interest has grown significantly in software systems and applications that are aware of users' social context to make pervasive applications more intelligent and accessible. Thus, socially-aware systems have further advanced context-aware systems taking account of human social context such as social relationships to enable the...
There is an increasing demand for context-aware adaptive services that can evolve at runtime in response to unanticipated changes in their environments or functionalities. Enabling the runtime evolution of such context-aware adaptive services is still a major challenge. In this paper, we introduce a novel approach to tackle this challenge. At the development time, our approach explicitly models a...
Verifying adaptive behavior is a critical challenge in the development of context-aware systems due to their complexity and uncertainty. This paper presents our novel model-based approach that provides a modeling framework to (1) specify the structural and behavioral aspects of a context-aware system, (2) define invariants of the system that need to be satisfied regardless of the adaptations, and...
Many software systems need to be developed with adaptation in mind, where at runtime they need to detect changes in their operating environments and adapt themselves to cope with these changes while achieving or preserving the overall system goals. In recent years, there has been much research in the communities of context-aware systems and self-adaptive systems with their own foci. However, addressing...
The convergence of Internet and mobile devices has radically changed the way people communicate and interact with each other, and demand for applications that are "social" enough to assist their daily interactions. To support such device mediated interactions, the social relationships between actors need to be systematically modeled and represented. In addition, an application facilitating...
Automotive software has increasingly become context-aware and adaptive to deal with dynamically changing environments. This paper presents our novel service-based approach to support the structural and behavioral adaptation of automotive telematics. We adopt services to (1) provide physical context facts and (2) facilitate context-aware interactions between entities of automotive telematics systems...
In ubiquitous computing environments, certain entities (or actors) often need to interact with each other in achieving a joint goal in a dynamically changing context. To perform such interactions in a seamless manner, the actors need to be aware of not only their physical context (e.g. location) but also their changing relationships with respect to the particular task or goal. The latter interaction-oriented...
