Abstract

A system and method for providing a search result based on a personal network are disclosed. The search result providing system may include a search term reception unit, a personal network extraction unit, and a search result providing unit which may receive a search term from a user. The personal network extraction unit may extract at least one of a personal network associated with the search term, and a personal network associated with the user. The search result providing unit may provide documents associated with the personal networks as a search result of the search term. A search result optimized for the user may be provided to the user by searching for information corresponding to the search term from communities joined by another user having similar interests to that of the user, or communities joined by the user, based on personal networks of the user.

Claims

1. A system to provide a search result, the system comprising:

a search term reception unit to receive a search term;

a processor to extract information corresponding to at least one of a first personal network associated with the search term and a second personal network different than the first personal network; and

a search result providing unit to provide a document associated with at least one of the first personal network and the second personal network as a search result of the search term.

2. The system of claim 1, further comprising:

a neighbor information extraction unit to extract information corresponding to at least one neighbor having interests corresponding to interests of a user, the user providing the search term to the search term reception unit; and

a personal network setting unit to set, as a personal network of the user, at least one of communities joined by the user, the at least one neighbor, and communities joined by the at least one neighbor.

3. The system of claim 2, wherein the neighbor information extraction unit extracts information corresponding to a first neighbor having interests corresponding to interests of the user and information corresponding to an N^th neighbor having interests corresponding to the interests of the user,

wherein N is a real number being equal to or greater than 2.

4. The system of claim 2, wherein the neighbor information extraction unit extracts the information corresponding to the at least one neighbor based on a profile of the user or neighbor information of the user.

5. The system of claim 4, wherein the neighbor information extraction unit provides the profile of the user using keywords provided in a document associated with the user, and extracts information from the at least one neighbor using the provided profile of the user.

6. The system of claim 4, wherein the neighbor information of the user is determined based on at least one of a social network of the user, an e-mail address book, and Really Simple Syndication (RSS) subscription information.

7. The system of claim 2, wherein the personal network extraction unit arranges the set personal network of the user based on at least one of an association with the search term and an association with the user, and extracts information corresponding to a neighbor or a community in a ranked personal network.

8. The system of claim 1, wherein the search result providing unit provides the document associated with the at least one of the first personal network and the second personal network as a search result of the search term by arranging the document among documents associated with the search term, based on an association between a user providing the search term and the at least one of the first personal network and the second personal network.

9. The system of claim 1, wherein the search result providing unit provides the document associated with the at least one of the first personal network and the second personal network as a search result of the search term by arranging the document among documents associated with the search term, based on an order of net association comprising an association with respect to the search term and an association between a user providing the search term and the at least one of the first personal network and the second personal network.

10. The system of claim 9, wherein the search result providing unit places, in the search result of the search term, documents associated with communities joined by a user at a higher ranking than documents associated with communities joined by at least one neighbor of the user.

11. The system of claim 2, wherein the search result providing unit recommends communities not yet joined by the user among the communities joined by the at least one neighbor, based on at least one of an association with the search term and an association with the user.

12. A method that utilizes a processor to provide a search result, the method comprising:

receiving a search term;

extracting, via the processor, information corresponding to at least one of a first personal network associated with the search term and a second personal network different than the first personal network; and

providing a document associated with at least one of the first personal networks and the second personal network as a search result of the search term.

13. The method of claim 12, further comprising:

extracting information corresponding to at least one neighbor having interests corresponding to interests of a user, the user providing the search term to the search term reception unit;

setting at least one of communities joined by the user, the at least one neighbor, and communities joined by the at least one neighbor, to be a personal network of the user.

14. The method of claim 13, wherein extracting information corresponding to the at least one neighbor comprises extracting information corresponding to a first neighbor having interests corresponding to the interests of the user, and extracting information corresponding to an N^th neighbor having interests corresponding to the interests of the user.

15. The method of claim 13, wherein extracting information corresponding to the at least one neighbor comprises extracting information corresponding to the at least one neighbor based on a profile of the user or neighbor information of the user.

16. The method of claim 15, wherein extracting information corresponding to the at least one neighbor comprises:

providing the profile of the user using keywords provided in a document associated with the user; and

extracting the information corresponding to the at least one neighbor using the provided profile of the user.

17. The method of claim 15, wherein the neighbor information of the user is determined based on at least one of a social network of the user, an e-mail address book, and Really Simple Syndication (RSS) subscription information.

18. The method of claim 13, wherein extracting information corresponding to at least one of the first personal network and the second personal network comprises:

arranging the personal network of the user based on at least one of an association with the search term and an association with the user; and

extracting information corresponding to a neighbor or a community in a ranked personal network.

19. The method of claim 12, wherein the providing comprises providing the document associated with the at least one of the first personal network and the second personal network as a search result of the search term by arranging the document associated with the at least one of the first personal network and the second personal network among documents associated with the search term, based on an association between a user providing the search term and the at least one of the first personal network and the second personal network.

20. The method of claim 12, wherein the providing comprises providing the document associated with the at least one of the first personal network and the second personal network as a search result of the search term by arranging the document associated with the at least one of the first personal network and the second personal network among documents associated with the search term based on an order of net association comprising an association with respect to the search term and an association between a user providing the search term and the at least one of the first personal network and the second personal network.

21. The method of claim 18, wherein the providing comprises placing, in the search result of the search term, documents associated with the communities joined by the user at a higher ranking than documents associated with communities joined by the at least one neighbor.

22. The method of claim 13, wherein the providing comprises recommending communities not yet joined by the user among the communities joined by the at least one neighbor, based on at least one of an association with the search term and an association with the user.
