Abstract
Techniques are provided for prediction locations of users that submit search queries. A query is received at a search engine. An inverted index is searched to identify one or more geographical locations associated with one or more terms of the received query. The inverted index lists a plurality of query terms and one or more geographical locations associated with each query term. Each geographic location that is associated with a listed query term in the inverted index is a determined location for at least one user previously having submitted the listed term in a search query. A geographical location is predicted for a user that submitted the received query based on the identified one or more geographical locations. In this manner, a location is predicted for the user based on similar queries previously submitted by users.
