基于聚类分析的案例库分层组织结构
首发时间:2011-05-11
摘要:基于案例推理包括案例检索、案例重用、案例修正、案例存储四个基本步骤。案例检索是案例推理中最重要的一个步骤。为了提高案例检索的效率,本文提出了一种基于聚类分析的案例库分层组织结构。利用聚类分析的思想将案例库分为代表案例库和子案例库。案例检索时先从代表案例库中检索出相似的案例再从相应的子案例库中检索案例。最后以一个实例说明如何构建一个基于聚类分析的案例库分层组织结构。

A Two-level-structure for the Composition of Cases Based on Cluster Analysis
Abstract:There are four basic procedures in case-based reasoning, case retrieving, case reusing, case revising and case retaining. Case retrieving is the most important procedure in case-based reasoning. The paper represents a two-level-structure for the composition of cases based on cluster analysis to improve the efficiency of case retrieving. Case base is divided into a typical case base and several sub case bases. First retrieve the similar case from the typical case base, then retrieve similar cases from the corresponding sub case base. Finally introduce an example to explain how to build the two-level-structure we mentioned.
Keywords: case-based reasoning case retrieving cluster analysis
