چکیده

Ontologies have been suggested as a means to ensure interoperability of Ambient Intelligence (AmI) applications as well as effectiveness within different sensory environments. We introduce a new logical language specifically tailored to the task of ontology design for AmI applications. This language has known advantages of description logics, namely a precisely defined semantics and a brief, intuitive syntax; and it facilitates formalising knowledge about contexts: a unified syntax for representing containment relations makes it easy to specify that a context is spatially or temporally contained in another, that two contexts share a certain group of agents or objects, or that an application is in a state that requires it to adapt its behaviour. RÉSUMÉ. Les ontologies ont été proposées comme un moyen d’assurer l’interopérabilité des applications de l’Intelligence Diffuse (AmI en anglais) ainsi que leur efficacité au sein de différents environnements sensoriels. Nous proposons un nouveau langage logique dédié à la tâche de conception d’ontologies pour des applications de l’Intelligence diffuse. Ce langage possède les avantages connus des logiques de description, à savoir une sémantique définie précise et une syntaxe simple et intuitive. Il facilite la formalisation des connaissances sur les contextes. Une syntaxe unifiée pour représenter les relations d’endiguement facilite la spécification d’un contexte spatialement ou temporellement inclus dans un autre contexte, et que les deux contextes partagent un certain groupe d’agents ou d’objets, ou qu’une application est dans un état qui lui demande d’adopter tel comportement.

Context-aware Modeling for Spatio-temporal Data Transmitted from a Wireless Body Sensor Network

Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...

Context Aware Framework – A Middleware for Ubiquitous Computing

Context Aware Computing enables the applications or systems to provide relevant services and information to users, based on the information collected from various entities involved in the environment. It also provides the ability for the systems to acquire and do reasoning on the situational context. In this paper we discuss about various research challenges for building context aware system co...

A Context Model for Context-Aware System Design Towards the Ambient Intelligence Vision: Experiences in the eTourism Domain

The Ambient Intelligence (AmI) vision implies the concept of “smart spaces” populated by intelligent entities. While most implementations focus strictly on local applications of “AmI”, we think of an AmI scenario as a federation of instances of local and application AmI domains. In order to deal with distributed context handling in AmI domains, we propose a context model suitable for distribute...
