Abstract

A method and system of modulating search result relevancy use various types of user browsing activities. In particular, a client assistant residing in a client computer monitors movements of a user controlled pointer in a web browser, e.g., when the pointer moves into a predefined region and when it moves out of the predefined region. A server then determines a relevancy value between an informational item associated with the predefined region and a search query according to the pointer hover period. When preparing a new search result responsive to a search query, the server re-orders identified informational items in accordance with their respective relevancy values such that more relevant items appear before less relevant ones. The server also uses the relevancy values to determine and/or adjust the content of an one-box result associated with a search query.

Claims

1. A method of providing search results, comprising:

at a client;

presenting, in response to a search query, a plurality of search results received from a remotely located search engine, each search result occupying a respective region on a display;

determining a hover period comprising a length of time that a user hovers a user-controlled pointer over the display region occupied by a respective search result of the plurality of search results without user selection of the respective search result; and

transmitting, to a server, information about the length of the hover period and the respective search result over which the user-controlled pointer was hovering;

at a server;

updating a relevancy value of the respective search result at least partially in accordance with the received user hover periods; and

in response to a second search query after the update of the relevancy value, identifying a set of search results for the second search query in accordance with their relevancy values, the set of search results including the respective search result whose relevancy value has been updated.

2. The method of claim 1, wherein the plurality of search results are displayed in a single display region.

3. The method of claim 1, including receiving from the server and displaying additional information concerning the search result over which the user-controlled pointer was hovering.

4. The method of claim 1,

wherein the respective search result includes at least a first portion and a second portion and the hover period with respect to the first and second portions have different weights when they are used for adjusting the search result'"'"'s relevancy value.

5. The method of claim 4, wherein the first portion of the search result is a descriptor and the second portion of the search result is a snippet.

6. The method of claim 4, wherein the adjusting the search result'"'"'s relevancy value occurs if the hover period is greater than a threshold value.

7. A method of providing search results responsive to search queries, comprising:

at a server system;

receiving from client devices user hover periods associated with a search result that corresponds to a first search query, a respective user hover period comprising information about a length of time that a user hovers a user-controlled pointer over a display region occupied by the search result without user selection of the search result;

updating a relevancy value of the search result at least partially in accordance with the received user hover periods; and

in response to a second search query after the update of the relevancy value, identifying a set of search results for the second search query in accordance with their relevancy values, the set of search results including the search result whose respective relevancy value has been updated.

8. A method of providing search results responsive to search queries, comprising:

at a server system;

receiving from client devices user hover periods associated with a plurality of search results which correspond to multiple search queries, a respective user hover period comprising information about a length of time that a user hovers a user-controlled pointer over a display region occupied by a respective search result of the plurality of search results without user selection of the respective search result;

updating relevancy values of the search results at least partially in accordance with their respective user hover periods; and

in response to a search query after the update of the relevancy values, identifying a set of search results for the search query in accordance with their relevancy values, the set of search results including at least one search result whose respective relevancy value has been updated.

9. The method of claim 8, wherein updating relevancy values includes:

retrieving impression data associated with the plurality of search results provided to the client devices in response to the search queries, wherein the impression data comprises data identifying how many times and in what order the search results in the plurality of search results have been provided to the client devices in response to the search queries;

receiving from at least a subset of the client devices the client attention data, the client attention data including the user hover period associated with search result if the hover period is greater than a threshold value; and

updating the relevancy values for at least a subset of the plurality of search results in accordance with their respective impression data and client attention data.

10. The method of claim 9, wherein the updating the relevancy values includes:

generating at least one client attention coefficient for each of the search results in the subset in accordance with the impression data and the client attention data corresponding to the search results;

combining the at least one client attention coefficient associated with each search result in the subset with at least one other query-independent metric of the search result'"'"'s importance or popularity; and

generating a relevancy value for each search result in the subset in accordance with its combined client attention coefficients and the at least one other query-independent metric of the search item'"'"'s importance or popularity.

11. A server system for providing search results responsive to search queries, comprising:

a memory;

one or more processors; and

a program, wherein the program is stored in the memory and configured to be executed by the one or more processors, the program comprising;

instructions for receiving from client devices user hover periods associated with a plurality of search results which correspond to multiple search queries, a respective user hover period comprising information about a length of time that a user hovers a user-controlled pointer over a display region occupied by a respective search result of the plurality of search results without user selection of the respective search result;

instructions for updating relevancy values of the search results at least partially in accordance with their respective user hover periods; and

instructions for responding to a search query after the update of the relevancy values by identifying a set of search results for the search query in accordance with their relevancy values, the set of search results including at least one search result whose respective relevancy value has been updated.

12. The system of claim 11, wherein updating relevancy values includes:

instructions for retrieving impression data associated with the plurality of search results provided to the client devices in response to the search queries, wherein the impression data comprises data identifying how many times and in what order the search results in the plurality of search results have been provided to the client devices in response to the search queries;

instructions for receiving from at least a subset of the client devices the client attention data, the client attention data including the user hover period associated with search result if the hover period is greater than a threshold value; and

instructions for updating the relevancy values for at least a subset of the plurality of search results in accordance with their respective impression data and client attention data.

13. The system of claim 12, wherein the updating the relevancy values includes:
