DISCOVERY OF BEHAVIOR-BASED ITEM RELATIONSHIPS
First Claim
1. A computer-implemented method of discovering behavior-based relationships between items represented in an electronic catalog, the method comprising:
- storing a plurality of session records in computer storage, each session record being specific to a respective browsing session of a user and identifying a plurality of items selected by the user for viewing in an electronic catalog during the browsing session, at least some of said session records corresponding to different users than other browsing records;
generating data values representing strengths of relationships between particular ones of said items, wherein generating the data values comprises, for a pair of items, determining, based on the plurality of session records, the number of browsing sessions in which both items of the pair were selected for viewing; and
generating a mapping of items to related items based at least partly on said data values;
said method performed by a computing system that comprises one or more computers.

Abstract
Various processes are disclosed for discovering item relationships between particular items, such as products represented in an electronic catalog, based on monitored user behaviors (e.g., item viewing activities, item purchases, shopping cart activities, etc.). The discovered item relationships may, for example, be used to generate personalized item recommendations for users, and/or to supplement item detail pages of an electronic catalog with lists of related items. Also disclosed are processes for generating personalized item recommendations based on users'"'"' search activities and browse node visits.

20. A system for discovering and exposing behavior-based relationships between items represented in an electronic catalog, the system comprising:
-
a computer data repository that stores records of item viewing activities of a plurality of users, said records of item viewing activities identifying particular items selected by users for viewing in an electronic catalog of items; a first component that is configured to generate a mapping of items to related items based on the records of item viewing activities, said mapping reflecting item-viewing-based relationships between items, said first component comprising computer hardware; and a second component that is configured to use the mapping to incorporate lists of related items into item detail pages of the electronic catalog. - View Dependent Claims (21, 22, 23, 24)
