4. What is Tagging? Popularized by websites associated with Web 2.0, tagging associates freely determined keywords (tags) with a particular resource. What can be tagged: Photos URLs Podcasts Blog posts Computer games Music Video Tagging lets you build a set of links that remains updateable and discoverable for a long time.
5. Tagging Methods delicious Social bookmarking service. Primary use of delicious is to store your bookmarks online. Use tags to organize and remember your bookmarks. more flexible system than folders Potential for collaborative organization of resources. Connecting people and information online.
7. Tagging Methods Flickr Image and video hosting website. Popular Web site for users to share personal photographs. Photo submitters organize images using tags. Also used for tagging Web links (sites, pages, and blog postings) Online photo management system.
10. Enter Tag Clouds A user interface element commonly associated with folksonomy datasets. A visual depiction of content tags used on a website. depicted in a larger font or otherwise emphasized displayed order is generally alphabetical Selecting a single tag within a tag cloud will generally lead to a collection of items that are associated with that tag.
11. Tag Cloud from LibraryThing
12. Tag Cloud from AuthorStream
13. Types of Tag Clouds A tag cloud for each item. Global tag clouds. where the frequencies are aggregated over all items and users Tags are used as a categorization method for content items.
14. How Tag Clouds Work A tag cloud is a set of related tags. produced via computer algorithms typical tag clouds have between 30 and 150 tags weights are represented using font sizes or other visual clues interactive can appear in alphabetical order or in a random order you can tweak your clouds with different fonts, layouts, and color schemes
15. Folksonomy The result of personal free tagging of information and objects (anything with a URL) for ones own retrieval. The tagging is done in a social environment (usually shared and open to others). Folksonomy is created from the act of tagging by the person consuming the information" (Vander Wal, 2007). Since 2004, social software applications and their use of tagging have continued to increase in popularity particularly in sites dedicated to such applications.
16. This is the Question of the Day Folksonomies have the potential to add much value to library catalogs by enabling users to store, maintain, and organize items of interest in the catalog using their own tags. What do you think?
17. Tagging Methods for Collaborative Cataloging LibraryThing Social networking site for cataloging books. Features tagged records, member ratings, recommendations and reviews of books owned by registered members. Use of Z39.05 to find cataloging data for specific books and application program interface (API) to generate ISBNs. Links are forged via the tags with other sites and other web users. Tags categorize books by how users think of them.
19. Potential Advantages of Tagging for Libraries Tagging supplements library catalogs. Folksonomies are inclusive, current and facilitate discovery. Improves browsing. information retrieval benefits Broader description. improves breadth of coverage Users can’t find something if they don’t know LCSH, this way they can use terms they are familiar with.
20. Proponents Would Say… Increases number of classifiers. More metadata available for images. more tags, additional terms Facilitates tags for foreign languages. Neologisms and common terminology added. A way to display subject headings visually. Traditional OPACs and ILS were designed in the early days of the Web and have not kept pace with changing times.
21. But don’t let me convince you….
22. Tagging Studies Spiteri (2007) Study of 3 tagging sites showed that less that 25% of the tags were ambiguous, most follow NISO guidelines. Lund & Washburn (2008) Study shows that LibraryThing tags provide more descriptive information and more access points to library monographs than LCSH.
25. Tagging Studies Morrison (2008) In Web searching, search engines still return slightly more relevant results, but results returned by both a folksonomy and a search engine were better than those returned by any single search engine. Kipp (2008) Tags used as guides to search terms. Searchers using tags as a starting point. Randomized tagging vs. online.
26. Potential Disadvantages of Tagging for Libraries No authority control. Misspellings, abbreviations, accuracy issues No one checking inaccuracies. Tags are personal, no broad applications. Addition of non-descriptive tags. Tags are less precise.
27. Controversies for Libraries Traditional view that only professionally trained catalogers are qualified to assign appropriate access points to library materials. LCSH can only be assigned by trained catalogers. OPACs contain richly described data in a consistent format.
28. Tagging Studies Wetterstrom (2008) New Zealand study showed that 75% of tags did not match LCSH, tags most often were popular terms or related terms from a different point of view. Gelernter (2007) Quantitative analysis of collaborative tags to look at differences in controlled vs. uncontrolled vocabularies. LCSH prevails.
29. ILS Involvement in Social Networking Software SirsiDynixThe current direction for e-Library and Enterprise, the flagship SirsiDynix public interface products, is built on the belief that the value in tagging functionality become really apparent when there is a critical mass of data created by a community. Our intent therefore is to tap into as broad a community as possible. SirsiDynix is actively pursuing partnerships with communities that transcend the library industry. Examples of such communities include the users of LibraryThing, Goodreads, and ChiliFresh. We are finding ways to integrate tagging content from communities like that into the SirsiDynix public interface experience.Allen County Public Library

34. ILS Involvement VTLSWe are indeed planning on providing the ability to add tags to books and see tags added by others, along with a tag cloud. This will be available in the software prior to its planned release this Summer. One other note that you might find interesting is that we are also planning on having an interface in our Virtua product, internal code name Chamo, with a seamless interface with Drupal, a Content Management System. Based on feedback from our customers, we believe that the future direction of the OPAC lies with being another type of content provided by a website which contains many varied types of content. Our goal is to allow customers to use Drupal as the front end meaning that they can easily customize the website to meet their particular needs while also providing a single sign-on and single search to access all content of the website, including the OPAC.
35. ILS Involvement PolarisWe have new initiative with reviews and tagging. We’ve partnered with ChiliFresh for reviews and just recently, LibraryThing for tagging. The ChiliFresh integration has been released into the field and Brownsburg Public has it: http://www.brownsburg.lib.in.us/If you do a popular material search (harry potter), you’ll see many reviews. Note in our upcoming Version 3.5, we eliminate the pop-up window and will incorporate the reviews using AJAX technology –very cool! The LibraryThing integration is completed, but is not yet released into the field (although we have a customer Glendora Public Library, CA) using it in a not-quite-transparent way.
36. ILS Involvement TLCWe have community features for book clubs, discussion groups, shared interests, and Web participation for:TaggingList sharingUser reviewsAnd search and display features for:RSS result feedsRSS indexing from popular or local Web sites
37. ILS Involvement FollettThis is a feature we are considering for one of our future releases of Destiny. No definite date for this at this time.For examples of libraries working with LibraryThing go to the LT wiki: http://www.librarything.com/wiki/index.php/LTF L:Libraries_using_LibraryThing_for_Libraries
38. Other Products AquaBrowser Search and discovery platform for libraries. The product assigns the tags, it looks at certain fields in the bib record and calculates frequency and utilizes weighting of the fields. No staff time is involved – the tag cloud is part of the product on the results page. Patrons are not contributing, there is no editing done at this time. Advantages, it gives users a different way to browse. Baltimore County Public Library
