BLACK BOARD 5)
A zone of common access in a distributed artificial intelligence network where information can be traded between autonomous modules.
E. BUCHBERGER describes it as the: "Global data structure which stores all the intermediate and final results in an expert system" He adds: "The blackboard is mostly hierarchically organized. Any data exchange between programs (or knowledge sources) ensues on the blackboard" (1987, p.29).
Another possible communication mode is by reciprocal sending of messages between the modules. In this case criteria of channel availability and periodicity must be established.
This, interestingly, seems a good model of the exchange of information in human systems: an example could be the electronic trade boards in stock markets, which information, furthermore, can be transmitted over electronic networks.
