Abstract

A computer-implemented method for an anonymous personalized recommendation is provided. The method includes receiving select server fingerprints selected from server fingerprints based on predetermined metrics. The server fingerprints correspond to a plurality of public entities and each server fingerprint includes encoded information about a corresponding public entity. The method also includes generating a user fingerprint based on user information associated with a user, the user fingerprint comprising encoded user information. The method further includes comparing the user fingerprint with the select server fingerprints to select a server fingerprint for recommendation, generating a recommendation of a public entity corresponding to the server fingerprint for recommendation, and displaying the recommendation. Systems and machine-readable media are also provided.

Claims

1. A computer-implemented method for anonymously recommending public entities, the method comprising:

receiving, at a client of a user from a server, a number of select server fingerprints selected from server fingerprints based on predetermined metrics, the server fingerprints corresponding to a plurality of public entities, wherein

the predetermined metrics comprise at least one of user-defined criteria communicated to the server from the client and popularity of the plurality of public entities,

each server fingerprint comprises encoded information about a corresponding public entity, the encoded information comprising information for identifying the corresponding public entity and information for determining whether to recommend the public entity to a user;

generating, at the client, a user fingerprint based on user information associated with the user, the user fingerprint comprising encoded user information, wherein the user information comprises information representative of the user'"'"'s interests and wherein the user fingerprint is not transmitted outside the client;

comparing, at the client, the user fingerprint with the select server fingerprints to select at least one server fingerprint for recommendation;

generating, at the client, at least one recommendation of a public entity corresponding to the at least one server fingerprint for recommendation; and

displaying the at least one recommendation.

2. The method of claim 1, further comprising receiving a search result based on an information search request made by the user and modifying the search result based on the generated recommendation.

3. The method of claim 1, further comprising storing the received select server fingerprints in a data store.

4. The method of claim 3, further comprising:

updating the user fingerprint based on user feedback;

comparing the updated user fingerprint with the stored select server fingerprints to select an updated server fingerprint for recommendation; and

generating an updated recommendation of a public entity corresponding to the updated server fingerprint for recommendation.

5. The method of claim 1, wherein the plurality of public entities comprise at least one of a web site, an article, a blog, and a user on a social networking site.

6. The method of claim 1, wherein the encoded information about the corresponding public entity comprises relevancy values corresponding to a plurality of keywords, each of the relevancy values representing relevancy of the corresponding public entity to each keyword.

7. The method of claim 1, wherein the user information comprises at least one of a search history of the user, web page access history of the user, and web page bookmarks of the user.

8. The method of claim 1, wherein the encoded user information comprises relevancy values corresponding to a plurality of keywords, each of the relevancy values representing relevancy of the user information to each keyword.

9. The method of claim 1, wherein the select server fingerprints are selected based on at least one of popularity of the corresponding public entity, a category of public entities requested by the user, geographic location associated with the user, and language requested by the user.

10. The method of claim 1, wherein the encoded information is encoded to compress a size of the each server finger print.

11. The method of claim 1, further comprising communicating a request for the select server fingerprints to a server by conforming to a network protocol;

wherein the select server fingerprints are received in response to the request for the select server fingerprints.

12. The method of claim 11, wherein in the step of selecting the server fingerprints to communicate to the client, the server fingerprints are selected based on information generated as part of the network protocol.

13. A system for anonymously recommending public entities, the system comprising:

a memory storing executable instructions; and

a processor coupled to the memory configured to execute the stored executable instructions to;

receive at a client of a user, a number of select server fingerprints, wherein the select server fingerprints are selected from server fingerprints based on predetermined metrics, and wherein the server fingerprints correspond to a plurality of public entities, wherein,

the predetermined metrics comprise at least one of user-defined criteria communicated to the server from the client and popularity of the plurality of public entities,

each server fingerprint comprises encoded information about a corresponding public entity, the encoded information comprising information for identifying the corresponding public entity and information for determining whether to recommend the public entity to a user;

generate, at the client, a user fingerprint based on user information associated with the user, the user fingerprint comprising encoded user information, wherein the user information comprises information representative of the user'"'"'s interests and wherein the user fingerprint is not transmitted outside the client;

compare, at the client, the user fingerprint with the select server fingerprints to select at least one server fingerprint for recommendation;

generate, at the client, at least one recommendation of a public entity corresponding to the at least one server fingerprint for recommendation;

receive, at the client, a search result based on an information search request made by the user;

modify, at the client, the search result based on the generated recommendation; and

display the modified search result.

14. The system of claim 13, further comprising a data store, wherein the processor is further configured to:

store the select server fingerprints in the data store;

update the user fingerprint based on user feedback;

compare the updated user fingerprint with the stored select server fingerprints to select an updated server fingerprint for recommendation; and

generate an updated recommendation of a public entity corresponding to the updated server fingerprint for recommendation.

15. The system of claim 13, wherein the plurality of public entities comprise at least one of a web site, an article, a blog, and a user on a social networking site.

16. The system of claim 13, wherein the encoded information about the corresponding public entity comprises relevancy values corresponding to a plurality of keywords, each of the relevancy values representing relevancy of the corresponding public entity to each keyword.

17. The system of claim 13, wherein the user information comprises at least one of a search history of the user, web page access history of the user, and web page bookmarks of the user.

18. The system of claim 13, wherein the encoded user information comprises relevancy values corresponding to a plurality of keywords, each of the relevancy values representing relevancy of the user information to each keyword.

19. The system of claim 13, wherein the select server fingerprints are selected based on at least one of popularity of the corresponding public entity, a category of public entities requested by the user, geographic location associated with the user, and language requested by the user.

20. A machine-readable storage medium comprising machine-readable instructions for causing a processor to execute a method for anonymously recommending public entities, the method comprising:

receiving, at a client of a user from a server, a number of select server fingerprints selected from server fingerprints based on predetermined metrics, the server fingerprints corresponding to a plurality of public entities, wherein

the select server fingerprints are received in response to a user action and the predetermined metrics comprise at least one of user-defined criteria communicated to the server from the client and popularity of the plurality of public entities,

each server fingerprint comprises encoded information about a corresponding public entity, the encoded information comprising information for identifying the corresponding public entity and information for determining whether to recommend the public entity to a user;

generating, at the client, a user fingerprint based on user information associated with the user, the user fingerprint comprising encoded user information, wherein the user information comprises information representative of the user'"'"'s interests and wherein the user fingerprint is not transmitted outside the client;

comparing, at the client, the user fingerprint with the select server fingerprints to select at least one server fingerprint for recommendation;

generating, at the client, at least one recommendation of a public entity corresponding to the at least one server fingerprint for recommendation; and

displaying the at least one recommendation.
