案例式推理 (CaseBased Reasoning CBR) 是知识表达的一种新方法 最主要就是利用先前的经验来解决问题 在 CBR 中 知识是以过去的案例来表示 而需要解决类似问题时 便使用这些经验来引导推理
简单地说 CaseBased Reasoning 就是
人类推理的过程
推理过程的表达
在应用程序发展上解决问题的一种方法论
如果您总是搞不清楚前向推理(forward chaining)后向推理(backward chaining) goaldirected reasoning certainty factors 这些名词而您的领域知识又很难用 ifthen 的规则方式表达 但却有大量的案例足以取样则用 CBR的方式来解决问题应是不错的选择
