US Patent 7343326 System and method for providing product recommendations

A dynamic merchandising system for presenting product recommendations to customers. The system and method generally creates for each of a plurality of products in a plurality of purchase orders a list of purchased-with products, i.e., products that were purchased with each of the plurality of products in each of the plurality of purchase orders. At the same time that the purchased-with product lists are created, or in another step, the same plurality of purchase orders are examined and, using the concept of “self organizing lists,” the lists of purchased-with products are ordered in a meaningful manner. The ordering of the products in a purchased-with list may then be considered when recommending products.
