A Rule-Based Ontology for Context-Aware Computing

Pervasive computing is the vision of technology that is invisibly embedded in natural surroundings. Users are offered unobtrusive services that require minimal attention. This paper proposes a rule-based ontology (RBO) for modeling context in pervasive computing environments, and for supporting logic based context reasoning. RBO takes a rule-based approach based on the event-condition-action pattern. Users specify when and what should be notified to them by using a convenient RBO rule definition. In addition, the implementation of rule reasoning of RBO with OWL is discussed.
