Faviki is a tool that brings together social bookmarking and Wikipedia. It lets you tag your bookmarks using Wikipedia concepts as tags. In Faviki, everybody uses same tags from the world's largest collection of knowledge!
Faviki is a social bookmarking tool which allows users to use common, predefined tags to annotate web pages. Using the Wikipedia collection of articles as a source of a universal controlled vocabulary, it provides so-called ‘semantic tags’. In this way, web pages saved by users are not just described by random words but connected to uniquely defined concepts.
DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link other data sets on the Web to Wikipedia data.
