The Application of Cluster Analysis Method in Case-Based Reasoning System

摘要

In the case-based reasoning system, it is the key and core of the system to quickly and accurately retrieve the appropriate case from the case base. Through case study, the case base will continue to increase. This paper presents in a case-based reasoning system, using cluster analysis techniques in case retrieval. User-entered target cases is matched with the abstract case to find the most similar abstract case, and then use case retrieval again in these abstract cases to get one or more similar specific cases. The cluster analysis was used to establish a multilevel index for the case base to improve the case retrieval efficiency.
