Abstract: A method for selecting a target group of customers for promoting a product is based on data representing individual buying patterns for a pool of customers over a set of products a product to be promoted. A first subset of customers is selected whose buying patterns can form a behavioral benchmark for the selection of the target group of customers. A market model for the product set is constructed and a second subset of customers is selected who are considered to be potentially interested in a product to be promoted. The second subset of customers is scored according to their similarity to customer segments in the benchmark customer market model and a third subset is selected based upon their scores. Members of the third subset are matched to products according to product segments for which they have demonstrated similarity. Offer parameters indicating collaborative promotions can then be output.
