The “folk” part of folksonomy is about ordinary web citizens creating knowledge. It’s about harnessing the power and knowledge of the many, making it possible for grandmas in the Netherlands and precocious seventh graders to collaborate on expanding the world’s knowledge. Folksonomy pertains specifically to ordinary citizens categorizing the web through tagging—the ‘onomy’ part of the word pertaining to taxonomy. Other ‘folksy’ projects include efforts like wikipedia which is the creation of web pages in a collaborative manner. In this paper, we discuss a new type of collaborative knowledge creation—folkclustering. Folkclustering is the many creating lists of web resources. Whereas Vivisimo and others cluster search results for users, using algorithmic methods, folkclustering is about ordinary users clustering resources together for other users. Perhaps the most popular example is Amazon’s Listmania.
