Abstract
An expanded queries data structure is described. The data structure is produced on the basis of a set of seed queries, and consists of entries each specifying an expanded query submitted by a user that has been determined to have a high degree of relatedness to at least a plurality of the seed queries of the set. The expanded queries specified by the entries of the expanded queries data structure can be used to define a segment of users expected to have interests characterized by the seed queries.
