Abstract

A rule-based kernel system to support reasoning within the blackboard problem architecture has been developed, with enough generality to support a number of expert system projects. The blackboard allows diverse expert-system modules to cooperate in solving complex design problems, making use of network communication to reduce difficulties with combining programs in various languages and operating systems. Features of the internal structure of the kernel allow it to be adapted readily to new problem areas and to new configurations of expert modules. From our experience we derive some design principles for enabling multi-expert cooperation, and for using expert knowledge effectively.
