Enhancing a Taxonomy for Health Information Technology: An Exploratory Study of User Input Towards Folksonomy

The U.S. Agency for Healthcare Research and Quality has created a public website to disseminate critical information regarding its health information technology initiative. The website is maintained by AHRQ's Natiomal Resource Center (NRC) for Health Information Technology. In the latest continuous quality improvement project, the NRC used the site's search logs to extract user-generated search phrases. The phrases were then compared to the site's controlled vocabulary with respect to language, grammar, and search precision. Results of the comparison demonstrate that search log data can be a cost-effective way to improve controlled vocabularies as well as information retrieval. User-entered search phrases were found to also share many similarities with folksonomy tags

A cautious partnership: The growing acceptance of folksonomy as a complement to indexing digital images and catalogs

As archives and museums place their photographic collections on the Web, the cost and time of indexing and assigning metadata to these images grows. One potential solution is to allow users to assign metadata to images, a practice known as folksonomy. While detractors label folksonomy as imprecise, sloppy, and overly focused on the needs of individual users, proponents applaud it as being directly tied to users\u27 vocabularies, inexpensive, and a means of directly engaging users. Suggestions for improvements to folksonomy include providing more structure to the tags users can supply, allowing feedback on user supplied tags, and even turning the assignment of metadata into a cooperative online game. Despite limited data on its effectiveness in generating terms relevant to user searches, folksonomy was advocated by the Library of Congress in 2008, and is beginning to be implemented by some libraries as a supplement to their OPAC for users accustomed to searching through Web engines. This paper discusses whether folksonomy can be seen as a substitute for traditional indexing and cataloging methods
