Abstract
Methods, systems, and apparatus, including computer program products, for determining rewrite source-rewrite target similarity scores. In one aspect the method includes receiving a rewrite source-rewrite target pair; identifying first queries that include the rewrite source and second queries that include the rewrite target; identifying a first web document referenced by a first search result responsive to the first query; identifying third queries for which the first web document was referenced by a third search result responsive to the third query; identifying a second web document that was referenced by a second search result responsive to the second query; identifying one or more fourth queries for which the second web document was referenced by a fourth search result responsive to the fourth query; and determining a similarity score for the rewrite source-rewrite target pair based on a measure of matching terms between third query terms and fourth query terms.
