Collaborative user query refinement
View Patent ↗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.
1. A computer-implemented method comprising:
receiving multiple series of queries;
determining that each of the multiple series of queries were submitted by a user when seeking information that satisfies a single information need;
determining that a starting point of each of the multiple series of queries is the same, the starting point being at least one query submitted chronologically before other queries included in the multiple series of queries;
determining that an end point of at least some of the multiple series of queries differs, the end point being at least one query submitted chronologically after the at least one query representing the starting point;
in response to determining that the starting point of each of the multiple series of queries is the same and that the ending point of at least some of the multiple series of queries differs:
identifying a subset of end points of the multiple series of queries that excludes at least the end point found in a minimum number of the multiple series of queries; and
generating a query reformulation path that associates the starting point with the subset of end points; and
storing the generated query reformulation path to enable presentation of the subset of end points in response to receipt of the at least one query representing the starting point.
2. The method of claim 1 further comprising:
accessing at least one second query reformulation path;

5. The method of claim 1 wherein:
identifying the subset of end points of the multiple series of queries that excludes at least the end point found in the minimum number of the multiple series of queries comprises identifying the end point found in a maximum number of the multiple series of queries;
