Semantic Web in a Pervasive Context-Aware Architecture
نویسندگان
چکیده
This document describes a new approach that explores the use of Semantic Web languages in building an architecture for supporting context-aware systems. This new architecture called Context Broker Architecture (CoBrA) differs from other architectures in using the Web Ontlogy 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. We also describe the use of CoBrA and its associated ontologies in prototyping an intelligent meeting room.

A semantic-aware role-based access control model for pervasive computing environments
Access control in open and dynamic Pervasive Computing Environments (PCEs) is a very complex mechanism and encompasses various new requirements. In fact, in such environments, context information should be used in access control decision process; however, it is not applicable to gather all context information completely and accurately all the time. Thus, a suitable access control model for PCEs...
متن کاملA Context-aware Architecture for Mental Model Sharing through Semantic Movement in Intelligent Agents
Recent studies in multi-agent systems are paying increasingly more attention to the paradigm of designing intelligent agents with human inspired concepts. One of the main cognitive concepts driving the core of many recent approaches in multi agent systems is shared mental models. In this paper, we propose an architecture for sharing mental models based on a new concept called semantic movement....
متن کاملThe Role of the Semantic Web in Pervasive Context-Aware Systems
This paper describes an ontology expressed in OWL for supporting agent based context-aware systems in a pervasive computing environment. Defining an explicit representation of the ontology can help agents to reason about contexts and share context knowledge in a dynamic environment. Central to our architecture is the presence of an intelligent context broker that accepts context related informa...
متن کاملWeb-Based Semantic Pervasive Computing Services
Pervasive Computing refers to a seamless and invisible computing environment which provides dynamic, proactive and context-aware services to the user by acquiring context knowledge from the environment and composing available services. In this paper, we demonstrate how heterogeneous Web services can be made interoperable and used to support Pervasive Computing. We present an architecture how a ...
متن کاملAn Intelligent Broker for Context-Aware Systems
We describe Context Broker Architecture (CoBrA) – a new architecture for supporting context-aware systems in smart spaces. Our architecture explores the use of Semantic Web languages for defining and publishing a context ontology, for sharing information about a context and for reasoning over such information. Central to our architecture is a broker agent that maintains a shared model of the co...
