Abstract
A first query and a second query, both of which were submitted by a first user to identify information that satisfies a single information need of the first user, are received. The first query and the second query are stored in association with one another and based on a chronological order in which the first query and the second query were submitted by the first user to generate a first query reformulation path. A query is received from a user and more than one query reformulation path is accessed. The received query is compared with queries included in the accessed query reformulation paths to identify a relationship between the received query and a query included in a relevant query reformulation path. One or more prevalent end points is determined based on the relevant query reformulation path and at least one of the prevalent end points is presented to the user.
