Automatic tagging of content based on a corpus of previously tagged and untagged content

摘要

An automated mechanism of automatically tagging media files such as podcasts, blog entries, and videos, for example, with meaningful taxonomy tags. The mechanism provides active (or automated) assistance in assigning appropriate tags to a particular piece of content (or media). Included is a system for automatic tagging of audio streams on the Internet, whether from audio files, or from the audio tracks of audio/video files, using the folksonomy of the Internet. The audio streams may be provided by the media author. For example, the author can make a recording to be posted on a website, and use the system to automatically suggest (via prompted author interaction) folksonomically appropriate tags for the media recording. Alternatively, the system can be used in an automated fashion to develop and assign without any intervention by the author.
