Semantic context reasoning using ontology based models

Abstract

New mobile computing technologies and the increasing use of portable devices have pushed the development of the so-called context-aware applications. This new class of applications aims at improving human-computer interactions by supporting dynamic adaptations according to context changes. This paper discusses the suitability of using ontologies for modeling context information and presents the design, implementation and applicability of an ontology based context interpreter. The proposed interpreter is responsible for inferring new context information in a context-aware services platform. © Springer-Verlag Berlin Heidelberg 2007.
