This architecture called Context Broker Architecture (CoBrA) differs from other architectures in using theWeb Ontology Language OWL for modeling ontologies of context and for supporting context reasoning. Central to our architecture is a broker agent that maintains a shared model of context for all computing entities in the space and enforces the privacy policies defined by the users when sharing their contextual information. We describe the use of CoBrA, its associated ontologies, and its privacy protection mechanism in an intelligent meeting room prototype.10 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
