A context-aware system in ubiquitous environment: a research guide assistant

The ubiquitous environnient is to support people in their everyday life in an inconspicuous and unobtrusive way. This requires that information of the person and her preferences, liking, and habits are available in the ubiquitous system. In this paper, we propose the context aware system that can provide the tailored information service for user in ubiquitous computing environment. The system architecture is composed of 4 domain niodels that can perform some pre-defined tasks independently. And we suggest the hybrid algorithm combined with fuuy and Bayesiun network to reason what information is suitable for user environment. Finally, the system is applied to RGA(Research Guide Assistant) and the efficiency and usefulness is described.
