The Case Retrieval Strategy Based on Hierarchical Clustering

Abstract

Case-based reasoning technology has been widely applied in many areas. This study first clustered thecae base according to hierarchy, then on the foundation of which designed a retrieval strategy based on non-isomorphic case base, analyzed the hierarchal clustering rules of case base, and mainly discussed the case retrieval strategy based on clustering. The results of the experiment show that this method can efficiently improve the utilization rate of cases in case base as well as the success rate of thecae retrieval.
