范例推理中面向对象的范例表示研究

结合范例推理的具体特点，按照面向对象的形式定义，给出范例的面向对象表示方法.通过类的层次信息，方便地表示范例复杂的结构信息;它一方面克服了属性-值对表示法无法表示复杂结构范例的缺陷，另一方面将领域知识通过约束规则与范例的表示有机结合起来.在范例相似性计算上，区分类内相似性和类间相似性，使得相似性表示尽可能准确和科学，从而有效地拓展了范例推理系统中的知识表示能力.

Object-Oriented Case Representation in Case-Based Reasoning

This paper proposes a new object-oriented case representation based on the formalize definition of object and the specification of Case-based Reasoning. It represents the complex case structural information through class hierarchy. The new method not only overcomes limitations that attribute-value case representation can not represent complex structured cases, but also combines domain knowledge and case representation through constraint rules. At the point of case similarity, this paper divides it into two parts, inter-class similarity and intra-class similarity, which improve correctness of similarity representation as high as possible. The object-oriented case representation can effectively reinforce the representing ability of knowledge in the CBR system.
