Abstract

A semantic client, a semantic information management server, a method of generating semantic information, a method of searching semantic information, and a computer program recording medium for performing the methods, the semantic client including: an identification (ID) generator to generate an ID of a target content; and a descriptor generator to generate a descriptor that defines correlations between the target content and one or more other contents. Furthermore, the semantic information management server includes: a semantic information database (DB) to store a descriptor including information about an ID of contents and correlations among the contents and other contents related to the contents; and an agent to search semantic information of the related contents with reference to the semantic information DB. Therefore, since contents have their own IDs, a user can easily search the contents.

Claims

1. A semantic client to manage a plurality of contents, the semantic client comprising:

an identification (ID) generator to generate an ID of a target content from among the plurality of contents; and

a descriptor generator to generate a descriptor that defines correlations between the target content and one or more of the plurality of contents.

2. The semantic client as claimed in claim 1, further comprising a controller to determine a type of content that the target content is.

3. The semantic client as claimed in claim 1, wherein the descriptor generator does not generate the descriptor if the target content is basic content.

4. The semantic client as claimed in claim 2, wherein the controller controls the ID generator to generate the ID and the descriptor generator to generate the descriptor of the target content if the controller determines that the target content is derivative content.

5. The semantic client as claimed in claim 2, wherein the controller controls the ID generator to generate the ID of the target content with reference to an ID of basic content corresponding to the target content if the controller determines that the target content is derivative content.

6. The semantic client as claimed in claim 1, wherein the ID generator generates the ID of the target content as a hash Globally Unique Identifier using a binary combination of data of the target content.

7. The semantic client as claimed in claim 1, further comprising a network interface to transmit the ID and/or the descriptor to a semantic information management server connected to the semantic client through a network.

8. The semantic client as claimed in claim 7, further comprising:

a user interface to receive a query to search content related to the target content,

wherein the network interface transmits the query to the semantic information management server, and the network interface receives semantic information of the related content from the semantic information management server.

9. The semantic client as claimed in claim 8, further comprising:

a searcher to search one or more external devices connected to the semantic client through the network for the related content according to the received semantic information of the related content.

10. A semantic information management server to manage a plurality of contents, the semantic information management server comprising:

a semantic information DB (database) to store an identification (ID) of a target content, a descriptor comprising information about correlations among the target content and other contents related to the target content, and IDs of the other contents related to the target content; and

an agent to search semantic information of the related contents with reference to the semantic information DB.

11. The semantic information management server as claimed in claim 10, wherein the agent comprises:

an ID manager to interpret the ID of the target content; and

a descriptor manager to interpret the descriptor of the target content.

12. The semantic information management server as claimed in claim 11, further comprising a controller to search the semantic information of the related contents with reference to interpretation results of the ID manager and the descriptor manager.

13. The semantic information management server as claimed in claim 12, further comprising:

a network interface to receive a query to search for the contents related to the target content from a semantic client connected to the semantic information management server through a network, and to transmit the semantic information of the related contents searched by the controller to the semantic client.

14. A method of generating semantic information of a target content, the method comprising:

determining whether the target content is basic content or derivative content; and

generating semantic information of the target content according to whether the target content is determined to be the basic content or the derivative content.

15. The method as claimed in claim 14, wherein the generating of the semantic information of the target content comprises generating a proper identification (ID) of the target content if the target content is determined to be the basic content.

16. The method as claimed in claim 14, wherein the generating of the semantic information of the target content comprises generating a proper ID of the target content if the target content is determined to be the derivative content.

17. The method as claimed in claim 16, wherein:

the generating of the semantic information of the target content further comprises if the target content is determined to be the derivative content, obtaining an ID of a corresponding basic content; and

the generating of the ID of the target content comprises generating the ID of the target content with reference to the ID of the corresponding basic content.

18. The method as claimed in claim 14, wherein the generating of the semantic information of the target content comprises generating a descriptor of the target content if the target content is determined to be the derivative content, the descriptor defining correlations between the target content and one or more related contents.

19. The method as claimed in claim 18, wherein the generating of the semantic information of the target content further comprises obtaining an ID and a descriptor of the one or more related contents.

20. The method as claimed in claim 14, further comprises transmitting the generated semantic information to a semantic information management server.

21. The method as claimed in claim 18, wherein the descriptor comprises a definition for a correlation between one type of content and contents related to the one type of contents.

22. The method as claimed in claim 18, wherein the descriptor is written in an XML (Extensible Markup Language) format.

23. The method as claimed in claim 14, wherein the target content is a moving picture file, a still image file, an audio file, a text file, a multimedia file, a frame, an object, a uniform resource locator (URL), an Internet Protocol (IP) address, and a phone number.

24. The method as claimed in claim 16, wherein the generating of the proper ID comprises generating a hash Globally Unique Identifier (GUID) using a binary combination of data of the target content.

30. A computer-readable recording medium having embodied thereon a computer program for executing the method of claim 14.

25. A method of searching semantic information of contents related to a target content, the method comprising:

if the target content is basic content, interpreting an identification (ID) of the target content;

if the target content is derivative content, interpreting the ID and a descriptor of the target content; and

searching the semantic information of the related contents with reference to interpretation results of the ID and/or the descriptor.

26. The method as claimed in claim 25, wherein the semantic information is searched with reference to IDs and/or descriptors of the related contents.

27. The method as claimed in claim 25, further comprising:

receiving a query from a semantic client to search the semantic information of the related contents; and

interpreting the query.

28. The method as claimed in claim 25, further comprising:

receiving an ID of the target content from a semantic client; and

determining whether the target content is the basic content or the derivative content.

29. The method as claimed in claim 27, further comprising transmitting the semantic information of the searched related contents to the semantic client.

31. A computer-readable recording medium having embodied thereon a computer program for executing the method of claim 25.
