Abstract

The goal of this paper is to present a new method of clustering products based only on the market-basket data from the retail store. The presented approach uses a special way of computing the dissimilarity matrix on which Ward’s hierarchical clustering method is used. The similarity matrix stems from the co-occurrence of products in same basket as a utility data. As a similar are denoted products which have similar co-occurring products and simultaneously are not often present in the same basket. Hence, the method does not require the identification of the customer, neither the data from fixed time frame, which is an advantage over commonly used methods. The method is reasonably fast even over huge dataset of tens of millions rows. The results are promising and easy to interpret.
