Design and Development of a Social Intelligence Based Context-Aware Middleware Using BlackBoard

The context-aware computing environment is changing due to recent development of the new computing devices and new concept of services. The systems are developing rapidly, but most of them focus on recognition of the collected information, not on the intelligent capability. In this paper, we defined a new context aware computing environment based on the concept of social intelligence, which implies an ability to share or utilize information by making a relationship, recognizes context by making an inference, and works in collaboration to offer services more efficiently. We have designed and developed a Social Intelligence based Context-Aware Middleware (SI-CAM), under the environment. The SI-CAM provides a service with following functions, multi context-awareness, context based task planning, and grouping intelligent entities for collaboration. The system is developed with blackboard based structure, and tested on virtual environment in the domain of ubiquitous restaurant. The experiment showed some significant results.
