Abstract

A method and system for providing search results only inclusive of valid webpage(s) to a user is disclosed, the method comprising: receiving a first search query from a first user; providing to the first user first search results obtained in response to the first search query; determining whether a webpage selected by the first user from the first search results is valid or not; receiving a second search query from a second user; providing to the second user second search results obtained in response to the second search query if it is determined that the webpage selected by the first user is valid; and correcting the second search results obtained in response to the second search query and providing the corrected second search results to the second user if it is determined that the webpage selected by the first user is not valid and is included in the second search results.

Claims

1. A method of providing search results comprising:

receiving a first search query from a first user;

providing to the first user first search results obtained in response to the first search query;

determining whether a webpage selected by the first user from the first search results is valid or not;

receiving a second search query from a second user;

providing to the second user second search results obtained in response to the second search query if it is determined that the webpage selected by the first user is valid; and

correcting the second search results obtained in response to the second search query and providing the corrected second search results to the second user if it is determined that the webpage selected by the first user is not valid and is included in the second search results.

2. The method according to claim 1, wherein the step of determining whether the selected webpage is valid or not comprises:

detecting whether a webpage is selected by the first user;

accessing, if it is detected that the webpage is selected by the first user, the selected webpage and analyzing validity of the selected webpage; and

storing the analysis results.

3. The method according to claim 1, wherein the step of correcting the second search results is performed by deleting from the second search results link information of the webpage having been determined to be invalid.

4. The method according to claim 1, wherein the step of correcting the second search results is performed by inserting into the second search results information informing that the webpage having been determined to be invalid is not valid.

5. The method according to claim 1, wherein the step of determining whether the selected webpage is valid or not is performed by determining whether the selected webpage has been deleted or not.

6. The method according to claim 5, wherein whether the selected webpage has been deleted or not is determined by searching the selected webpage for a particular pattern indicating the deletion of the webpage.

7. The method according to claim 1, wherein the step of determining whether the selected webpage is valid or not is performed by determining whether the selected webpage has been changed in comparison with a webpage pre-stored in a database.

8. The method according to claim 7, wherein whether the selected webpage has been changed or not is determined by comparing a hash-key value of text of the selected webpage with a hash-key value of text of the pre-stored webpage.

9. The method according to claim 7, wherein the pre-stored webpage is updated by the selected webpage if it is determined that the selected webpage has been changed.

13. A recording medium with a program readable by a computer to execute the method of claim 1.

10. A method of providing search results comprising:

determining whether a webpage selected by a first user is valid or not;

receiving a search query from a second user;

correcting search results obtained in response to the search query if it is determined that the webpage is not valid and is included in the search results; and

providing the corrected search results to the second user.

11. The method according to claim 10, wherein the step of determining whether the selected webpage is valid or not comprises:

accessing the selected webpage and analyzing validity of the selected webpage; and

storing the analysis results.

12. The method according to claim 10, wherein the step of correcting the search results is performed by deleting from the search results link information of the selected webpage or insert into the search results information informing that the selected webpage is not valid.

14. A system for providing search results comprising:

an interfacing unit for receiving first and second search queries from first and second user respectively, and providing to the first and second users first and second search results obtained in response to the first and second search queries;

a validity determining unit for determining validity of a webpage selected by the first user from the first search results; and

a search results correcting unit for correcting the second search results if it is determined by the validity determining unit that the selected webpage is invalid and is included in the second search results.

15. The system according to claim 14, wherein the validity determining unit comprises:

a detector for detecting whether a webpage is selected by the first user;

an analyzer for accessing, if it detected that the webpage is selected by the first user, the selected webpage and analyzing validity of the selected webpage; and

a storage for storing the analysis results.

16. The system according to claim 14, wherein the search results correcting unit deletes link from the second search results link information of the selected webpage.

17. The system according to claim 14, wherein the search results correcting unit inserts into the second search results information indicating the selected webpage is not valid.

18. The system according to claim 14, wherein the validity determining unit determines whether the selected webpage has been deleted or not.

19. The system according to claim 14, wherein the validity determining unit determines whether the selected webpage has been changed in comparison with a webpage pre-stored in a database.

20. The system according to claim 14, further comprising a searching unit for generating the first and second search results by executing search in response to the first and second search queries.
