Collaborative Tagging for Knowledge Sharing

“There has recently there been a great surge of interest in collaborative tagging as a means of facilitating knowledge sharing in social computing. Collaborative tagging refers to the process in which a community of users adds meta-information in the form of keywords or tags to Web content such as web pages, links, photographs and audio files on a centralized web server.

While collaborative tagging is only starting to be researched in the research community, it seems to address a real need on the Web as demonstrated by the growing popularity of tagging and annotation sites (see, flickr, technorati, RawSugar, Shadows, etc.); the most popular sites already have a combined user base of several millions.” – from the description of Collaborative Web Tagging Workshop
