Abstract:
1. A computer-implemented method of identifying behavior-based item relationships that are useful for generating item recommendations, the method comprising: detecting a behavior-based relationship between a first item represented in an electronic catalog and a second item represented in the electronic catalog, said behavior-based relationship based on user activity data reflective of item selections of a plurality of users; selecting, based at least partly on a price of the first item, a price-compatibility score generation function from a plurality of price-compatibility score generation functions, wherein each price-compatibility score generation function corresponds to a different respective price range; calculating a price compatibility score with the selected price-compatibility score generation function, said price compatibility score representing a degree to which the first and second items are compatible in price; determining, based at least partly on the price compatibility score, to map the first item to the second item in an item-to-item mapping structure; and after determining to map the first item to the second item, using the item-to-item mapping structure to generate personalized item recommendations for each of multiple users; wherein each of the above-recited steps of said method is performed by a computer system that comprises one or more computers.
