We outline a Semantic Web approach for considering the impact of context information on the trustworthiness of communication. We show that the contexts of message sender, receiver,...
: John entered his office. John left his office. The order of these updates to a context-aware system is important to reflect the state in the real world. Context information ob...
Recommender algorithms have been quite successfully employed in a variety of scenarios from filtering applications to recommendations of movies and books at Amazon.com. However, a...
Ubiquitous Web systems have to deal with varying context information in order to support context awareness. Accomplishing this requirement necessitates gathering, processing and r...
Abstract. Current research in context-awareness is biased toward low-level context information. High-level context information, however, poses several challenges to context managem...
Context information is used by pervasive networking and context-aware programs to adapt intelligently to different environments and user tasks. As the context information is poten...
Abstract. Ontology is a promising tool to model and reason about context information in pervasive computing environment. However, ontology does not support representation and reaso...
