Group items tagged

The Internet technologies of the subsequent generation have been profoundly social, as listservs, Usenet groups, discussion software, groupware, and Web-based communities have linked people around the world.

A leading form of this is a controversial new form of metadata, the folksonomy. Whereas traditional metadata is usually hierarchical (topics nested within topics), structured (e.g., the fields within Dublin Core), and predetermined by content authorities, folksonomic metadata consists of words that users generate and attach to content.

Folksonomic services fill up with tags rapidly enough to make information professionals take notice. Second, Web 2.0 services tend to provide tools for helping users with their folksonomies. Tags can be arranged into concept maps called “tag clouds,” which allow revisualization of the way one considers one’s work.5

The social bookmarking innovator del.icio.us automatically reminds users of previously deployed tags, suggests some tags, and notes tags used by others. Third, people tend to tag socially. That is, they learn from other taggers and respond to other, published groups of tags, or “tagsets.”6 There are of course limitations to folksonomies, including the difficulty in scaling up tags from several to many users and the problem of quickly grasping contextual shifts between tagsets. But the rapid adoption and growth of folksonomies is noteworthy
