The BLACKBOARD framework is a DYNAMIC group of independent entities that communicate and work together in order to solve some common problem. The knowledge sources adds a solution piece to the blackboard data structure when they (independently) think it’s APPROPRIATE. There is no centralized control mechanism that MAKES decisions as to when a knowledge SOURCE needs to contribute some piece of information. Rather the control entity states the conditions of when and each knowledge source need to contribute. The knowledge sources observe the commotion on the blackboard and contribute to progress independently.
