Research on a data mining algorithm based on concept hierarchy tree and its application in CRM

The method of concept hierarchy tree classifiers (CHTC) has been widely applied in today's large-scale data mining environments. This paper, after introducing the basic idea of data-mining algorithm based on CHTC, proposes an improved approach by making up for the defection of the existing concept exaltation algorithm to numerical attributes in the database. Moreover, a comparison of two algorithms in a practical case by testing on actual data has shown the effectiveness of the algorithm.
