Abstract
One embodiment of the present invention provides a system that that uses geographic data to identify correlated geographic synonyms in search queries. A correlated geographic synonym occurs when two terms that are possible synonyms should not be considered synonyms because they are associated with related geographic context. During operation, the system receives a term and a possible synonym for the term. The system then determines whether the term and the possible synonym are both present in a geographic data set. If so, the system uses the geographic data set to determine whether the possible synonym is a correlated geographic synonym for the term.
