  <description><![CDATA[Context Broker Architecture (CoBrA) is an agent based architecture for supporting context-aware systems in smart spaces (e.g., intelligent meeting rooms, smart homes, and smart vehicles). Central to this architecture is an intelligent agent called  context broker that maintains a shared model of context on the behalf of a community of agents, services, and devices in the space and provides privacy protections for the users in the space by enforcing the policy rules that they define.]]></description>

  <description><![CDATA[Objective. The objective is to develop a personal agent that can provide and maintain the contextual information about a user. Acting as a record-keeper, this agent tracks a user's context by acquiring information from external sources (e.g., the context brokers in different smart spaces). Acting as an information provider, this agent shares the updated context information about a user with systems that attempt to provide services to the user.

Building on a earlier pervasive computing system, EasyMeeting provides relevant services and information to meeting participants based on their situational needs. Our system exploits the context-aware support provided by the Context Broker Architecture (Cobra). Cobra's intelligent broker agent maintains ...]]></description>

  <description><![CDATA[Building smart meeting rooms requires the support of
a computing system architecture. In this paper, we
describe the Context Broker Architecture (CoBrA), a
broker-centric agent architecture for pervasive contextaware
systems. CoBrA exploits theWeb Ontology Language
OWL for supporting knowledge sharing and data
fusion, uses logic inferences for resolving and detecting
inconsistent context knowledge, and provides users
with a policy language to control their private information.
