TLDR
In this article, the development of appropriate context modeling concepts for pervasive computing, which can form the basis for such a context management infrastructure is discussed, and the model overcomes problems associated with previous context models, including their lack of formality and generality, and tackles issues such as wide variations in information quality, the existence of complex relationships amongst context information and temporal aspects of context.Abstract:
As computing becomes more pervasive, the nature of applications must change accordingly. In particular, applications must become more flexible in order to respond to highly dynamic computing environments, and more autonomous, to reflect the growing ratio of applications to users and the corresponding decline in the attention a user can devote to each. That is, applications must become more context-aware. To facilitate the programming of such applications, infrastructure is required to gather, manage, and disseminate context information to applications. This paper is concerned with the development of appropriate context modeling concepts for pervasive computing, which can form the basis for such a context management infrastructure. This model overcomes problems associated with previous context models, including their lack of formality and generality, and also tackles issues such as wide variations in information quality, the existence of complex relationships amongst context information and temporal aspects of context.read more

Ontology based context modeling and reasoning using OWL
TL;DR: An OWL encoded context ontology (CONON) is proposed for modeling context in pervasive computing environments, and for supporting logic-based context reasoning, and provides extensibility for adding domain-specific ontology in a hierarchical manner.

TL;DR: The requirements that context modelling and reasoning techniques should meet are discussed, including the modelling of a variety ofcontext information types and their relationships, of situations as abstractions of context information facts, of histories of contextInformation, and of uncertainty of context Information.

TL;DR: A layered real-time architecture for this kind of context-aware adaptation based on redundant collections of low-level sensors, which has shown that it is feasible to recognize contexts using sensors and that context information can be used to create new interaction metaphors.
