Behavior scoring model for coalition loyalty programs by using summary variables of transaction data

OKCashbag (OCB), the largest coalition loyalty program in Korea, offers a number of benefits such as sharing customer data with participating firms and cross-selling. There is great value in utilizing information pertaining to coalition loyal patrons. However, the size of transaction data is huge. We propose how to create necessary summary information by reducing the dimension of coalition transaction data. This information is then utilized to develop a behavior-scoring model. We expect that our study results can contribute to big data analysis for coalition loyalty program.

► Behavior-scoring model is proposed to identify loyalty patrons in coalition program.
► Summary variables for multivariate time series of coalition DB are introduced.
► This contributed to reduce the dimension of big customer transaction data.
