The blackboard model of problem solving

摘要: The first blackboard system was the HEARSAY-II speech understanding (Erman et al.,1980) that evolved between 1971 and 1976. Subsequently, many systems have been built similar organization run-time behavior. objectives of this article are (1) to define what is meant by "blackboard systems" (2) show richness diversity designs. begins with a discussion underlying concept behind all systems, model problem solving. In order bridge gap working framework, an extension basic introduced, including detailed description model's components their A does not come into existence on its own, usually abstraction examples. Section 2 history ideas traced, designs some application helped shape detailed. Part which will appear in next issue AI Magazine, describes contrasts discusses characteristics problems suitable for method
