Folksonomies have the potential to add much value to public library catalogues by enabling clients to: store, maintain, and organize items of interest in the catalogue using their own tags. The purpose of this paper is to examine how the tags that constitute folksonomies are structured. Tags were acquired over a thirty-day period from the daily tag logs of three folksonomy sites, Del.icio.us, Furl, and Technorati. The tags were evaluated against section 6 (choice and form of terms) of the National Information Standards Organization (NISO) guidelines for the construction of controlled vocabularies.Another paper on tagging is @toread and Cool: Tagging for Time, Task and Emotion by Margaret E.I. Kipp in Proceedings 8th Information Architecture Summit, Las Vegas, Nevada, USA.
This paper examines the use of non subject related tags in three social bookmarking tools (Del.icio.us, Connotea and Citeulike). Previous studies of Del.icio.us and Citeulike determined that many common tags are not directly subject related but are in fact affective tags dwelling on a user's emotional response to a document or are time and task related tags related to a users current projects or activities. A set of non subject tags from the previous studies was used to collect posts with non subject tags from the three listed social bookmarking tools. These tags have been analysed to examine their role in the tagging process.
