Abstract
The present invention provides a software facility for identifying the items most relevant to a current query based on items selected in connection with similar queries. In preferred embodiments of the invention, the facility receives a query specifying one or more query terms. In response, the facility generates a query result identifying a plurality of items that satisfy the query. The facility then produces a ranking value for at least a portion of the items identified in the query result by combining the relative frequencies with which users selected that item from the query results generated from queries specifying each of the terms specified by the query. The facility identifies as most relevant those items having the highest ranking values.

21. A method in a computing system for ranking items in a search result based on relevance of the items, the method comprising:
-
receiving a search query from a user that specifies one or more terms;
generating a query result identifying a plurality of items satisfying the query;
ranking multiple of the identified items by, identifying one or more demographic groups to which the user belongs;
for each of the multiple items, generating a rating for the item based on a frequency with which other users in the identified demographic groups purchased the item during a prior period of time; and
generating a ranking for each of the multiple items relative to the other multiple items based on the generated ratings; and
displaying the multiple items to the user in an order based on the generated ranking for those items, so that items purchased most frequently by other users in a demographic group to which a user belongs are displayed to the user before items purchased less frequently by those other users. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A method in a computing system for ranking items in a search result, the method comprising:
-
receiving one or more search terms for a user;
identifying a plurality of items that match at least one of the terms;
identifying one or more demographic groups to which the user belongs;
generating a relevance ranking for each of multiple of the identified items based on a number of selections of that item by users in the identified demographic groups during at least one prior period of time; and
providing an indication of the generated relevance rankings for the multiple items. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 49, 50)

59. A computing system configured to rank items in a query result, comprising:
-
a query result ranking component configured to, for each of multiple items identified among query results for a query from a user, generate a rank for the item based on prior selections of that item by users in one or more demographic groups for the user; and
an output device with which the query result ranking component can provide the generated rankings for the multiple items. - View Dependent Claims (60, 61)
