Identifying the items most relevant to a current query based on items selected in connection with similar queries
First Claim
1. 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 received search terms;
identifying one or more demographic groups to which the user belongs;
generating a relevance ranking for at least a portion of the identified items based at least in part upon rating scores associated with the identified demographic groups, each rating score representing a number of selections of an identified item by users in a respective demographic group during at least one prior period of time when the item is identified in results based on queries containing at least one of the search terms received for the user; and
providing a query result to the user, in response to the received one or more search terms, including at least a portion of the identified items ranked according to the generated relevance ranking.

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.

35. A computing system for ranking items in a search result, comprising:
-
an input subsystem that receives one or more search terms for a user; an item identification subsystem that identifies a plurality of items that match at least one of the search terms and that identifies one or more demographic groups to which the user belongs; a relevance ranking subsystem that generates a relevance ranking for at least a portion of the identified items based at least in part upon rating scores associated with the identified demographic groups, each rating score representing a number of selections of an identified item by users in a respective demographic group during at least one prior period of time when the item is identified in results provided for queries containing at least one of the search terms received for the user; and an output subsystem that provides a query result to the user, in response to the received one or more search terms, including at least a portion of the identified items ranked according to the generated relevance ranking.
