Data mining has received a lot of attention from practitioners. That is partly because it allows company to extract a set of useful knowledge about customers from database, thereby retaining current customers and magneting potential customers. This logic is especially essential in the field of credit card industry, where just 5% increase of number of customers is hewn to cause 120% increase in profit. The problem is how to retain current customers and even make them more loyal to company. However, previous studies lacked proposing extensive strategies of reducing the churning rate. In this sense, this study attempts to suggest such strategies by applying neural network, logistic regression, and C5.0 techniques to credit card data. We used a real data set of four years from 1997 to 2000, which were gathered from a credit card company. Experimental results revealed that our approach could yield robust strategies for retaining customers by reducing the churning rate.

Nowadays various new items are available, but limitation of searching effort makes it difficult for customers to search new items which they want to purchase. Therefore new item providers and customers need recommendation systems which recommend right items for right customers. In this research, we focus on the new item recommendation issue, and suggest preference boundary- based procedures which extend traditional content-based algorithm. We introduce the concept of preference boundary in a feature space to recommend new items. To find the preference boundary of a target customer, we suggest heuristic algorithms to find the centroid and the radius of preference boundary. To evaluate the performance of suggested procedures, we have conducted several experiments using real mobile transaction data and analyzed their results. Some discussions about our experimental results are also given with a further research area.

상위 $20\%$의 우량고객이 기업수익의 $80\%$를 기여한다는 파레토 법칙을 인용하지 않더라도 고객이 원하는 상품과 서비스를 지속적으로 제공함으로써 고객과의 지속적인 관계를 통한 고객과의 지속적인 관계유지, 특히 우량고객의 확보, 유지는 기업의 수익증대에 깊은 관계가 있으며 결국 기업의 생존을 가늠하는 길이 될 것이다. 최근에는 금융권간 업무영역이 무너지면서 모든 금융기관들은 우수고객 확보를 위해 영업력을 집중시키고 있다. 특히 수익기여도가 높은 우수고객에 대해서는 차별적인 우대서비스를 명시적으로 규정하고 우량고객 확보를 위한 생존을 건 경쟁이 벌어지고 있다. 따라서 우량고객은 자료를 통한 객관적이고 합리적 기준에 의해 확보되어야 한다. 본 연구에서는 이에 대한 방법론으로서 데이터베이스 모델링을 제시하며, 그 효과를 측정하도록 하고, 고객 속성에 따른 고객세분화에 이용될 수 있음을 보여준다.
