an annotation data display unit that displays the annotation data corresponding to the label specified by the user among the labels.

4. The annotation management system according to claim 3, wherein

the annotation content further contains a URL of a metafile describing a range that the media file is played back, or a metafile when the type of the annotation content is a video media file or an audio media file.

5. The annotation management system according to claim 4, further comprising:

a media server that manages the media file, wherein

the electronic document attachment program further includes an upload unit that uploads the media file to the media server when the media file is not opened.

6. The annotation management system according to claim 5, further comprising

a media analysis server having:

a document block dividing unit that divides the selected electronic document into document blocks;

a keyword extracting unit that extracts a keyword contained in the document blocks;

a document keyword appearance frequency detecting unit that detects the appearance frequency of the keyword in the document blocks;

a media block dividing unit that divides the media file into media blocks;

a voice recognizing unit that performs voice recognition of the keyword by using voice data in the media blocks;

a media keyword appearance frequency detecting unit that detects the appearance frequency of the keyword in the media blocks;

an association unit that associates the document blocks with the media blocks based on the appearance frequency of the keyword in the document blocks and the appearance frequency of the keyword in the media blocks;

a metafile generating unit that generates a metafile describing the range of the media file played back corresponding to the selected document block; and

an upload unit that uploads the metafile to the media server.

7. The annotation management system according to claim 5, further comprising

a media analysis server having:

a document block dividing unit that divides the selected electronic document into document blocks;

a keyword extracting unit that extracts a keyword contained in the document blocks;

a document keyword appearance frequency detecting unit that detects the appearance frequency of the keyword in the document blocks;

a media block dividing unit that divides the media file into media blocks;

a character recognizing unit that performs character recognition of the keyword by using dynamic image data in the media blocks;

a media keyword appearance frequency detecting unit that detects the appearance frequency of the keyword in the media blocks;

an association unit that associates the document blocks with the media blocks based on the appearance frequency of the keyword in the document blocks and the appearance frequency of the keyword in the media blocks;

a metafile generating unit that generates a metafile describing the range of the media file played back corresponding to the selected document block; and

an upload section that uploads the metafile to the media server.

8. The annotation management system according to claim 5, wherein

the electronic document attachment program further includes a metafile generating unit that determines the range that the media file is played back according to the user'"'"'s input to generate a metafile for playing back the range.

9. The annotation management system according to claim 3, wherein

the electronic document attachment program further includes a keyword extracting unit that extracts a keyword contained in the selected document block, and

the annotation data further contains the keyword.
