It Final Presentation

  1. 1. Social Cataloging in the Libraries<br />Charlie Terng<br />610:550:02<br />December 03, 2009<br />
  2. 2. Main Issue:<br />Traditional classification system<br />(controlled vocabulary)<br />‏<br />- vs -<br />Social tagging<br />
  3. 3. Terminology<br />Controlled vocabulary<br />An organized collection of words/phrases/names, structured to show the relationships between terms and concepts. <br />Examples: LCSH, MeSH.<br />Tags<br />User-generated metadata used to describe the “aboutness” of an object.<br />
  4. 4. Main differences<br />Controlled vocab:<br />Authoritative.<br />Structured as a hierarchy.<br />Ordered, systematic way to search for information.<br />Tagging:<br />Derived by the general public.<br />Unstructured.<br />More approachable, user-friendly way to search.<br />
  5. 5. Issues with controlled vocabulary<br />Hierarchy structure and specific terminology requires users to be knowledgeable or familiar in the subject area.<br />Pre-determined listing takes user element out of it.<br />“Look, but don&apos;t touch”. Non-interactive.<br />
  6. 6. What tags can offer<br />Cataloging system based on terms used by “regular people”.<br />More intuitive way of searching.<br />Free-flow path, no hierarchical structure.<br />Current, up-to-date terms.<br />Most importantly, more access points.<br />
  7. 7. Example<br />
  8. 8. Example<br />Library of Congress Subject Headings<br />
  9. 9. Example<br />LibraryThing tags<br />
  10. 10. So why not just use tags?<br />Quality/relevance of tags may vary (i.e., “spagging”).<br />Tag clouds, evaluation by librarians are possible solution.<br />Issues with specificity (i.e., squirrel topics).<br />Although, LT&apos;s new “Tagmash” seems to fix this.<br />Controlled vocabulary better for total recall.<br />
  11. 11. Which should OPACs use?<br />Not “either or”, but an integration of both. <br />Their strengths cover each other&apos;s weaknesses.<br />Different situations call for different methods.<br />They also work well together.<br />It&apos;s all about increasing access points.<br />
  12. 12. LTFL is on the job<br />1,512 libraries served.<br />37 in NJ:<br />LOGIN (20 libraries)‏<br />Atlantic County System (10 libraries)‏<br />Mount Laurel<br />East Brunswick Public<br />Camden County College<br />Highland Park Public<br />Cranbury Public<br />
