EXTRAPOLATION OF ITEM ATTRIBUTES BASED ON DETECTED ASSOCIATIONS BETWEEN THE ITEMS
First Claim
Patent Images
1. A computer system for detecting associations between items, the computer system comprising:
- an item data repository comprising a physical computer storage device, the item data repository configured to store item data representative of a plurality of items, the plurality of items comprising first items having an attribute and second items not known to have the attribute;
a content-based association mining component operative to detect substitution associations between the first and second items, at least in part, by analyzing content of the first and second items; and
an extrapolation component that comprises computer hardware, the extrapolation component operative to extrapolate the attribute from at least some of the first items to the second items based at least partly on a strength of the substitution associations between the first and second items.

Abstract
An attribute of a first item is extrapolated to a second item that is not known to have that attribute. The extrapolation occurs as a result of a substitution association detected between the first and second items. The substitution association may be detected based on an analysis of the content of the first and second items. The extrapolated attribute may be a behavioral association with a third item, in which case an inference is drawn that the second and third items are behaviorally related. The items may, for example, be products represented in an electronic catalog.

9. A computer-implemented method, comprising:
-
identifying a first item that has a first attribute, and a second item that is not known to have said first attribute; determining a strength of a substitution association between the first and second items based, said strength determined based on least partly on an automated analysis of content of the first and second items; and extrapolating the first attribute to the second item based on said strength of said substitution association; said method performed in its entirety by one or more computers. - View Dependent Claims (10, 11, 12, 13)
