IDENTIFYING LOW UTILITY ITEM-TO-ITEM ASSOCIATION MAPPINGS

A process is disclosed for using item price data to assess whether particular item-to-item associations are useful for generating item recommendations. In one embodiment, the process involves generating a compatibility score that represents a degree to which the two items of an item-to-item mapping are compatible in price. This score may then be used to determine whether to use the item-to-item association as a basis for generating item recommendations.
