Abstract
Apparatus, systems and methods for demoting repetitive search results are disclosed. Search results that are identified in both first set of search results and a second set of search results are determined to be repetitive search results. One or more of the repetitive search results can be demoted in the second set of search results. The demotion can be based on a relevancy threshold for the second set of search results.
Claims45
A computer implemented method, the method comprising:
- identifying a first set of search results responsive to a first query during a search session, each search result of the first set of search results having a corresponding ranking score, and the first set of search results being ranked according to ranking scores;
- identifying a second set of search results responsive to a second query during the search session, each search result of the second set of search results having a corresponding ranking score, and the second set of search results being ranked according to ranking scores, wherein the second query is different from the first query;
- identifying one or more repetitive search results, each of the one or more repetitive search results being a search result in both the first set of search results and the second set of search results;
- determining a score threshold for the second set of search results;
- identifying one or more candidate search results, candidate search results being repetitive search results that have a ranking score greater than the score threshold, the candidate search results comprising a first candidate search result, the first candidate search result having a ranking in the second set of search results according to the respective ranking scores of the first candidate search results;
- demoting the first candidate search result in the second set of search results by lowering the ranking of the first candidate search result in the second set of search results;
- and
- after demoting the first candidate search result in the second set of search results, providing the second set of search results in a response to the second query;
- wherein the identifying, determining, demoting and providing are performed by data processing apparatus.

A system comprising:
- one or more processors programmed to perform operations comprising:
- identifying a first set of search results responsive to a first query during a search session, each search result of the first set of search results having a corresponding ranking score, and the first set of search results being ranked according to ranking scores;
- identifying a second set of search results responsive to a second query during the search session, each search result of the second set of search results having a corresponding ranking score, and the second set of search results being ranked according to ranking scores, wherein the second query is different from the first query;
- identifying one or more repetitive search results, each of the one or more repetitive search results being a search result in both the first set of search results and the second set of search results;
- determining a score threshold for the second set of search results;
- identifying one or more candidate search results, candidate search results being repetitive search results that have a ranking score greater than the score threshold, the candidate search results comprising a first candidate search result, the first candidate search result having a ranking in the second set of search results according to the respective ranking scores of the first candidate search results;
- demoting the first candidate search result in the second set of search results by lowering the ranking of the first candidate search result in the second set of search results;
- and
- after demoting the first candidate search result in the second set of search results, providing the second set of search results in a response to the second query.

A non-transitory computer-readable storage medium having instructions stored thereon that, when executed by data processing apparatus, cause the data processing apparatus to perform operations comprising:
- identifying a first set of search results responsive to a first query during a search session, each search result of the first set of search results having a corresponding ranking score, and the first set of search results being ranked according to ranking scores;
- identifying a second set of search results responsive to a second query during the search session, each search result of the second set of search results having a corresponding ranking score, and the second set of search results being ranked according to ranking scores, wherein the second query is different from the first query;
- identifying one or more repetitive search results, each of the one or more repetitive search results being a search result in both the first set of search results and the second set of search results;
- determining a score threshold for the second set of search results;
- identifying one or more candidate search results, candidate search results being repetitive search results that have a ranking score greater than the score threshold, the candidate search results comprising a first candidate search result, the first candidate search result having a ranking in the second set of search results according to the respective ranking scores of the first candidate search results;
- demoting the first candidate search result in the second set of search results by lowering the ranking of the first candidate search result in the second set of search results;
- and
- after demoting the first candidate search result in the second set of search results, providing the second set of search results in a response to the second query.
