Abstract

A tag-based content classification method of classifying content based on a custom tag defined using user taste-based category information and a content reproduction apparatus to perform the method. The content classification method includes: analyzing content, and classifying the content based on whether the content comprises a first custom tag, the first custom tag and a second custom tag, the first custom tag, the second custom tag, and a tag, or the first custom tag and the tag.

Claims

1. A content classification method comprising:

analyzing content; and

if the content comprises a first custom tag, classifying the content based on the first custom tag,

wherein the first custom tag contains at least one item of category information based on a user'"'"'s taste.

2. The content classification method of claim 1, wherein if the content further comprises a second custom tag to monitor a pattern of use, the classifying of the content comprises classifying the content based on the first custom tag and the second custom tag.

3. The content classification method of claim 2, wherein if the content further comprises at least one content-based tag defined using content information-based category information, the classifying of the content comprises:

classifying the content based on the first custom tag and the second custom tag; and

classifying the content based on the content-based tags,

wherein one of the results of the classifying is selectively output according to a request of the user.

4. The content classification method of claim 3, wherein if at least one of the content-based tags is set as a custom tag, classifying the content based on the first custom tag comprises classifying the content based on the first custom tag, the second custom tag, and the at least one content-based tag set as the custom tag.

5. The content classification method of claim 1, wherein if the content further comprises at least one content-based tag defined using content information-based category information, the classifying of the content comprises:

classifying the content based on the first custom tag; and

classifying the content based on the content-based tags,

wherein one of the results of classifying is selectively output according to a request of the user.

6. The content classification method of claim 5, wherein if at least one of the content-based tags is set as a custom tag, the classifying the content based on the first custom tag comprises classifying the content based on the first custom tag and the at least one content-based tag set as the custom tag.

7. The content classification method of claim 2, wherein the analyzing of the content is performed when the content is received or when the content is reproduced.

8. The content classification method of claim 7, wherein if the analyzing of the content is performed when the content is reproduced, the classifying of the content comprises:

logging category information defined in the first custom tag and the second custom tag; and

storing a result of the logging;

wherein the content is classified by determining at least one of the importance of each of the category information and the importance of the content based on the result of the logging.

9. The content classification method of claim 8, further comprising displaying a result obtained by classifying the content so that at least one of the importance of the category information and the importance of the content is displayed.

10. The content classification method of claim 1, wherein the content comprises at least one of music-based content, image or video-based content, text-based content, and multimedia-based content.

11. The content classification method of claim 2, wherein if the content is music-based content, then:

the first custom tag and the second custom tag are set using at least one of a command field and a variable space of the content; and

if the content is image-based content, the first custom tag and the second custom tag are set using the command field of the content,

if the content is video-based content, the first custom tag and the second custom tag are set using a description space of the content, and

if the content is text-based content, the first custom tag and the second custom tag are set using a reserved area.

12. The content classification method of claim 1, wherein the classifying of the content comprises arranging the classified content in an order set by the user.

30. The content classification method of claim 1, wherein the content is a music file.

13. A content reproduction apparatus comprising:

a content analyzer to analyze received content; and

a content classifier to classify the content based on a first custom tag, if the content includes the first custom tag,

wherein the first custom tag contains at least one item of category information according to a user'"'"'s taste.

14. The content reproduction apparatus of claim 13, wherein if the content further comprises a second custom tag to monitor a pattern of use, the content classifier classifies the content based on the first custom tag and the second custom tag.

15. The content reproduction apparatus of claim 14, wherein if the content further comprises at least one content-based tag defined using content information-based category information, the content classifier comprises:

a first content classifier to classify the content based on the first custom tag and the second custom tag;

a second content classifier to classify the content based on the content-based tags; and

a selector to selectively output one of an output of the first content classifier and an output of the second content classifier according to a request of the user.

16. The content reproduction apparatus of claim 15, wherein if at least one of the content-based tags is set as a custom tag, the first content classifier classifies the content based on the first custom tag, the second custom tag, and the at least one content-based tag set as the custom tag.

17. The content reproduction apparatus of claim 14, wherein the content analyzer operates when the content is received by the content reproduction apparatus or when the content is reproduced in the content reproduction apparatus.

18. The content reproduction apparatus of claim 17, wherein the content classifier comprises:

a logging unit to log category information defined in the first custom tag and the second custom tag;

a storage unit to store a result of the logging; and

a content classification unit to classify the content by determining at least one of the importance of each of the items of category information and the importance of the content based on the result of the logging.

19. The content reproduction apparatus of claim 18, further comprising a display unit to display a result obtained by classifying the content so that the importance of each of the items of category information is displayed.

27. The content reproduction apparatus of claim 19, wherein the results are displayed in a cloud form with more important categories being displayed with a larger cloud than less important categories.

28. The content reproduction apparatus of claim 19, wherein the content is displayed in a slide show based on the result obtained by the content classifier.

29. The content reproduction apparatus of claim 27, wherein the importance of a category is determined by the amount of content in the category.

20. A computer readable medium comprising content and instructions that, when executed by a computer, cause the computer to perform a method comprising:

classifying the content based on a custom tag that contains category information relating to a user'"'"'s taste.

21. The computer readable medium of claim 20, wherein the content comprises a tag area containing a plurality of tags.

22. The computer readable medium of claim 20, wherein the content comprises a first tag area to hold content information-based tags and a second tag area to hold user information-based tags.

23. The computer readable medium of claim 22, wherein the second tag area holds pattern-of-use-based tags.

24. A method of classifying content, the method comprising:

classifying content based on a custom tag that contains category information relating to a user'"'"'s taste.

25. An apparatus comprising:

a content classifier to classify content on the basis of a custom tag that contains category information relating to a user'"'"'s taste.

26. A method of classifying content, the method comprising:

classifying content based on a custom tag that contains category information relating to the content'"'"'s pattern of use.
