Abstract: A system and method to evaluate the affinity of a collection of sale items to a user's interests. The affinity is a measure of how closely a user's interests match the contents of a collection (e.g., a collection of items selected by a seller, other user, or employee of the sales site). The method may determine the affinity of various collections by using a vector-space distance measure between the user's categories of interest and the relative percentages of various categories of items in each collection's. The method may also add a quality score for the collection to the affinity score and/or a random value to ensure that the system recommends high quality collections does not recommend the same set of collections every time the user logs in or visits the sales site.
