USING LOCATION FOR DETERMINING RELEVANCE BETWEEN QUERIES AND ADVERTISEMENTS

摘要

Relevance of advertisements provided in response to a query is improved based on locations associated with the query and the advertisement. A confidence level can optionally be determined for associated locations. The associated locations can be used to calculate a geographic distance between a query location and an advertisement location. A relevance can be determined for the advertisements based in part on the calculated geographic distances. The associated locations can also be compared to determine stacking and barrier relationships between locations.
