Title:
AGGREGATION OF AFFINITY LISTS
Document Type and Number:
WIPO Patent Application WO2007140084
Kind Code:
B1
Abstract:
A method is provided to aggregate a plurality of affinity lists to generate a single aggregated affinity list representing predicted affinities of a particular item, to other items, under a plurality of conditions. Each of the plurality of affinity lists represents an affinity of the particular item, to other items, under a subset of the plurality of conditions that is less than all of the plurality of conditions. For each of the affinity lists, a sub-list is determined corresponding to that affinity list by determining a subset of the entries of that affinity list based on the indicated affinity, and the indicated lifts of the entries of that affinity list. For each entry of the sub-list, a normalization indication is determined for that entry. Based on the determined normalization indications, the single aggregated affinity list is generated. Each entry of the single aggregated affinity list indicates a unique one of the other items as indicated by entries in one or more of the sub-lists.
