在案例推理CBR（Case Based Reasoning）中不同的检索方法对于案例的表示、组织和存贮具有直接影响。本文对由Lenz与Burkhard提出的基本案例检索网络给出了完整的、形式化的描述，基于这种描述建立起数学模型，进而对其进行扩展。在基本案例检索网络BCRN(Basic Case Retrieval Network)的扩展模型中，设置了一个“虚拟结点层”位于信息实体结点层与案例结点层之间，每一个虚结点表示由一组具有相似属性的信息实体抽象出来的一个概念。虚结点的激活是可控的，若激活向后传播用户可在信息实体层中找到更具体的信息，反之向前传播时用户则可找到更为抽象的信息或案例，从而可满足不同用户的查询需求。

The different retrieval methods have a far-reaching influence on representation, organization and store of the cases in CBR. This paper provides a complete and formal description for basic case retrieval network(BCRN) which is put forward by Lenz and Burkhard, establishes its mathematical model and then makes an extension for it. In extension of BCRN a “virtual nodes layer” is inserted between information entities nodes layer and case nodes layer, every virtual node denotes an abstract concept induced from a groups of IE in which the information entities have similar attribute. The activation of virtual node can be controlled. If the activation is transmitted backward, user can find some concrete information in the IE nodes layer and if forward then user can find more abstract information or cases, so this extension can satisfy the requirement for different user inquiry.
