Faviki is a social bookmarking tool that lets you use Wikipedia concepts as tags.

Faviki allows you to keep your own tags and connect them to common, universal concepts from the world's largest collection of knowledge!

Free-word tags do not have defined meanings, so it isn’t always clear what a particular tag represents. Does the tag “jaguar” represent the animal, the car company, or the operating system?

Faviki uses Common tags - unique, well-defined concepts from Wikipedia that allow you to state what a web page is exactly about, letting your computer understand you better.

Common tags allow you to find your bookmarks easier. Faviki categorizes your tags automatically, keeping your and your friend's bookmarks and interests well organized.

Common tagging is not limited to English language. Faviki lets you tag in 14 different languages by suggesting tags from DBpedia. All popular world languages are supported: Chinese, Japanese, French, German, Spanish, Portuguese, Italian, Russian...
