Patent ID: 8452785

Claim:
A non-transitory computer-readable medium embodying a program executable in a computing device, the program comprising: code that obtains an indication of a representative product and a value for an attribute associated with the representative product, the value being correlated with a first unit on a first scale of product classification; code that determines a range of values on a normalized scale for the attribute, the range of values being mapped to the value for the attribute, the range of values being determined for the representative product; code that identifies a plurality of similar products from a product catalog based at least in part on the range of values of the representative product, each of the similar products having a respective value for the attribute, each respective value being associated with a respective range of values on the normalized scale that overlaps the range of values of the representative product, the respective range of values for at least one of the similar products being correlated with a second unit on a second scale of product classification, wherein a degree of overlap of the respective range of values and the range of values of the representative product meets a threshold; and code that generates at least one network page that lists at least some of the similar products.
