The Case Clustering Algorithm Based on Rough Set

Based on rough set theory and case-based reasoning technology, the paper designs a case-clustering algorithm, introduces the rough set theory and the presentation form of case and case base, analyzes the structure of the cluster, and emphasizes on the merging algorithm of cluster. According to the experimental results, the method enhances the related extent of the cases in clustering through using of user´s feedback information, and effectively develops clustering to the cases of case base, so as to increase the efficiency of case retrieval.
