ABSTRACT

Due to the advent of ubiquitous computing environment, it is becoming a part of our commonlife style. And tremendous information is cumulated rapidly. In these trends, it is becoming a veryimportant technology to find out exact information in a large data to present users. Collaborativefiltering is the method based on other users' preferences, can not only reflect exact attributes of user but also still has the problem of sparsity and scalability, though it has been practically usedto improve these defects. In this paper, we propose clustering method by user’s features based onSOM for predicting purchase pattern in u-Commerce. it is necessary for us to make the clusterwith similarity by user’s features to be able to reflect attributes of the customer information inorder to find the items with same propensity in the cluster rapidly. The proposed makes the taskof clustering to apply the variable of featured vector for the user's information and RFM factorsbased on purchase history data. To verify improved performance of proposing system, we makeexperiments with dataset collected in a cosmetic internet shopping mall.
