Abstract
Achieving flexibility and efficiency in AI-based systems depends on how knowledge is organized and controlled. Blackboard-based architectures have proved their utility and power in the development of advanced high level AI-based applications. However much of them have been built from scratch, implementing the blackboard model according to the criteria that appeared most appropriate for a particular application. Some implementations like solution-based focusing architectures were designed for sake of execution efficiency, while others like blackboard control architectures were built for flexibility. In order to achieve these two fundamental and conflicting behaviors in blackboard systems, we propose a meta-level architecture which achieves opportunism and efficiency by organizing knowledge in a hierarchical manner and by managing it by way of a hybrid problem-solver.
