“…Folksonomies have become an important user‐driven approach to information indexing and retrieval (Dye, 2006; Furnas et al 2006; Golder and Huberman, 2006; Gordon‐Murnane, 2006; Guy and Tonkin, 2006; Kroski, 2008; Mathes, 2004; Noruzi, 2006; Peterson, 2006; Smith, 2008; Spiteri, 2006, 2007). They find application in:- collaborative web services such as Del.icio.us, Flickr, Last.fm and YouTube (Peters and Stock, 2007, 2008);
- library catalogs, e.g., PennTags (Sweda, 2006; Allen and Winkler, 2007), or “cataloguing 2.0” (Lyons and Tappeiner, 2008; Fifarek, 2008; Coyle, 2007; Weaver, 2007);
- corporate intranets (Fichter, 2006);
- museum catalogs (Trant, 2006); and
- commercial online information suppliers, e.g., Elsevier's Engineering Village and GENIOS' WISO (Stock, 2007b).
The strength of this approach is collaborative indexing; its weakness lies in information retrieval, as in most cases no relevance ranking exists (for a remarkable exception see Hotho et al (2006), and their system “BibSonomy”).…”
