Context information and context-awareness are some of the drivers for the Internet-of-Things paradigm, whereas a well-stated and defined model is the key element of any context information system. An appropriate context model ensures that the information gathered by a context information system can be represented, manipulated and accessed, and even linked to different systems and domains. This paper...
The present article describes an architecture proposed to identify the probable actions taken by an actor involved in a software development process. Such a process is a collaborative activity that can be associated to a context that comprises tasks and interactions for information exchange, targeting the manipulation of artifacts being developed. In this work, context is described using ontologies...
Traditionally, context models are created in a top down approach: first the application and its functionality are defined, and then the necessary context models are developed. Ontologies are now widely accepted as instrument for context modeling in pervasive computing applications, leveraging knowledge sharing, logic inference or knowledge reuse. They become the most common approach in recent years...
Context is considered by research community in pervasive computing, and particularly in context awareness, to be subject to the available environmental sensors to retrieve the suitable information to the user. For example, the users context is based on location information or even based on other deterministic information, such as time (morning, evening, 11:00 am, etc.). The challenge is to also consider...
The contribution of this paper is a novel service architecture for facilitating the development of context-aware applications in heterogeneous distributed environments. The requirements, architecture and functional validation of the architecture are contributed. The research problem addressed in the paper is dynamic acquisition and representation of context information and its efficient provisioning...
With the growing research interest in intelligent pervasive environments, there is a need to plan our layouts with sufficient criteria modelling so as to provide support for context-driven route navigation. However, current spatial layout modelling and simulation tools are largely inadequate for the task required since they are based on manual and heuristic techniques and do not provide a rich resource...
