An Ontology-Based Model for Context Information Management in Smart Spaces

Smart applications rely on middleware abstraction to interact with the environment in order to collect relevant information for context determination. Among the forms of representing context in smart spaces, ontologies have been used because of the possibility of sharing, reusing and also modelling the semantics of context, independent of programming language, operational system and/or middleware used. This work presents an ontology-based model to support applications in a ubiquitous environment. The proposed model was implemented and integrated into the uOS middleware, which has focus on service adaptability in smart spaces.
