Abstract

A system analyzes one or more search streams to detect one or more associations between a document and one or more queries in the one or more search streams. The system further derives a value for the document based on the detected associations and uses the derived value in evaluating a quality of the document with respect to one or more subsequent queries.

Claims

1. A non-transitory computer-readable memory device storing instructions, the instructions comprising:

one or more instructions which, when executed by at least one processor, cause the at least one processor to;

receive a same search query from a plurality of client devices;

identify a plurality of search result documents based on the search query;

receive information regarding selections, of the information regarding the plurality of search result documents, at the plurality of client devices in connection with the search query;

determine that a particular quantity of the selections, for information regarding a particular search result document of the plurality of search result documents, is greater than a quantity of the selections for information regarding one or more other search result documents of the plurality of search result documents;

assign a value to the particular search result document based on determining that the particular quantity of the selections is greater than the quantity of the selections for the information regarding the one or more other search result documents,

the value, assigned to the particular search result document, being based on;

a particular period of time, or

a respective network address associated with one or more of the plurality of client devices; and

use the value as a measure of quality for the particular search result document for a subsequently received search query that is associated with the search query.

2. The non-transitory computer-readable memory device of claim 1, where the value, assigned to the particular search result document, is limited for each client device of the plurality of client devices.

3. The non-transitory computer-readable memory device of claim 1, where the particular quantity of the selections includes a percentage.

4. The non-transitory computer-readable memory device of claim 1, where the one or more instructions which cause the at least one processor to use the value as the measure of quality comprise:

one or more instructions which, when executed by the at least one processor, cause the at least one processor to use the value as one factor of a plurality of factors to determine the measure of quality for the particular search result document for the subsequently received search query.

5. The non-transitory computer-readable memory device of claim 1, where the one or more instructions which cause the at least one processor to assign the value to the particular search result document comprise:

one or more instructions which, when executed by the at least one processor, cause the at least one processor to assign the value to one or more sites associated with the particular search result document.

6. The non-transitory computer-readable memory device of claim 1, where the one or more instructions to use the value as the measure of quality for the particular search result document include:

one or more instructions which, when executed by the at least one processor, cause the at least one processor to rank the particular search result document higher than another search result document, in a subsequently performed document scoring or ranking algorithm, based on the assigned value being higher than a value assigned to the other search result document.

7. The non-transitory computer-readable memory device of claim 1, where the particular quantity of the selections corresponds to a majority of the selections.

8. A system comprising:

an interface to receive a search query from a plurality of client devices; and

a processing unit, implemented at least partially in hardware, to;

identify a plurality of search result documents based on a search query,

provide information regarding the plurality of search result documents to the plurality of client devices,

receive information regarding selections, of the information regarding the plurality of search result documents, at the plurality of client devices in connection with the search query,

determine that a particular quantity of the selections, for information regarding a particular search result document of the plurality of search result documents, is greater than a quantity of the selections for information regarding one or more other search result documents of the plurality of search result documents,

assign a value to the particular search result document based on determining that the particular quantity of the selections, for the information regarding the particular search result document, is greater than the quantity of the selections for the information regarding the one or more other search result documents,

the value, assigned to the particular search result document, being based on;

a particular period of time, and

a respective network address associated with one or more of the plurality of client devices, and

use the assigned value as a measure of quality for the particular search result document for a subsequent search,

the subsequent search being associated with the search query.

9. The system of claim 8, where, when using the assigned value as the measure of quality for the particular search result document for the subsequent search, the processing unit is to:

rank the particular search result document higher than another search result document in a subsequently performed document scoring or ranking algorithm based on the assigned value being higher than a value assigned to the other search result document.

10. The system of claim 8, where, when assigning the value to the particular search result document, the processing unit is further to:

assign the value to one or more sites associated with the particular search result document.

11. The system of claim 8, where the particular quantity of the selections corresponds to a majority of the selections.

12. The system of claim 8, where, when using the assigned value as the measure of quality for the particular search result document for the subsequent search, the processing unit is to:

use the value as one factor of a plurality of factors to determine the measure of quality for the particular search result document for the subsequent search.

13. A method comprising:

receiving, at one or more processors, a same search query from a plurality of client devices;

identifying, by the one or more processors, search result documents based on the search query;

providing, by the one or more processors, information regarding the search result documents to the plurality of client devices;

receiving, at the one or more processors, information regarding selections, of the information regarding the search result documents, at the plurality of client devices in connection with the search query;

determining, by the one or more processors, that a particular quantity of the selections, for information regarding a particular search result document of the search result documents, is greater than a quantity of the selections for information regarding one or more other search result documents of the search result documents;

assigning, by the one or more processors, a value to the particular search result document based on determining that the particular quantity of the selections, for the information regarding the particular search result document, is greater than the quantity of the selections for the information regarding the one or more other search result documents,
