摘要
解释机制向用户提供了关于系统的认识窗口,是专家系统重要的组成部分.文中研究了通过真值维持结构记录求解的过程和结果,其中全局黑板结构记录全局信息,局部黑板结构记录局部信息,推理历史树记录问题的求解过程;给出了存储解释信息的关系数据库表结构;介绍了解释机制的方法,设计了系统静态信息、Why问题、How问题、推理轨迹跟踪等解释机制.
Explaination mechanism provides understanding window concerning system to customer, is an important component of expert system. The article studied process and result with true maintenance structure record solving, the overall situation blackboard structure record an overall situation information among them, the partial blackboard structure recorded a partial information, reasoning history tree recorded problem of solving process; gave the relation database form structure of saving explaination information; introduced explanation mechanism＇s method, designed system static information, Why problem, How problem, reasonning logically the track follows explain mechanism and so on.
