Abstract: This paper introduces a credit risk evaluation system of financial organization based on CBR and RBR, which combines the advantages of the two reasoning approaches. It focuses on the realization and improvement of CBR in this system, according to the algorithm of case matching similarity, this system uses the nearest neighbor algorithm, the improved NN algorithm and NN algorithm, and shows the casebase maintenance approach. It points out some questions of this system and brings forward the further study directions.
