Abstract:
1. A computer-implemented method comprising: receiving a query that includes a first geographic entity name; determining that a second geographic entity name that was identified as a substitute term for the first geographic entity name by a first substitution framework, was also identified as not a substitute term for the first geographic entity name by a second substitution framework; revising the query using the second geographic entity name to generate a revised query; obtaining search results that satisfy the revised query; and demoting a score of an obtained search result that corresponds to a document that includes the second geographic entity name based at least in part on determining that the second geographic entity name that was identified as a substitute term for the first geographic entity name by a first substitution framework was also identified as not a substitute term for the first geographic entity name by the second substitution framework.
