VideoTag is a fun one player tagging game. Tag some of the funniest videos on the internet, avoid the pitfalls and progress to the next level. See if you can make the top of the leaderboard and become the ultimate video tagger.
OntoTube is a two player quiz game for annotating videos. Both players have to answer questions about the video. The answers they provide are used for data generation.
Today’s conventional tagging mechanism, found on flickr, del.icio.us and youtube, allows users to associate web resources (i.e., documents, photos, videos and audios) with a set of keywords (i.e., tags). This mechanism works well for tagging resources that have a direct accessible URL. However, it falls short in being an effective tool for labeling the “deep” content of those resources — e.g., a partial clip from a youtube video.
