  • 1. Research & New Technologies Interest Group24 October 2005 DeweyBrowser & Curiouser Diane Vizine-Goetz OCLC Research

2. DeweyBrowser

  • The DeweyBrowser is a research prototype that supports searching and browsing collections of resources organized by Dewey
  • The prototype was developed to make the most of DDC numbers assigned to library materials and to explore the use of AJAX (Asynchronous JavaScript and XML)

3. DeweyBrowser

  • The interface presents search results at three levels, i.e., the three main summaries of Dewey
  • To use the prototype, a user navigates up and down the Dewey hierarchy by clicking on a category or enters a search term
  • The categories are color-coded to indicate where matching records occur
    • red, orange, and yellow (warm colors) many records
    • green and blue (cool colors) fewer records
    • white no matching records

4. DeweyBrowser

  • Summaries can be displayed in English, French, German, Spanish, or Swedish
  • Search and browse results can also be limited to resources written in a particular language

5. DeweyBrowser

  • The DeweyBrowser has been deployed over three collections of resources:
    • ebooks- 210,000+ electronic books
    • wcat 2.2 million of the most widely held WorldCat records
    • abr14 selected data from the Abridged Edition 14 of DDC
  • WorldCat and ebooks collections are linked to the Find in a Library Web service

6. Dewey Browser

  • The Abridged 14 collection includes a collaborative editing feature that enables authorized users to suggest index terms for a DDC class (Suggested terms)
  • Suggested terms will be delivered to interested users via RSS

7. DeweyBrowser & AJAX

  • AJAX is an approach to programming web interfaces that allows user interaction with a web page without refreshing the whole screen
  • Using AJAX speeds up the interface by only requesting parts of a page
  • Refreshing only the part of the screen that changes tends to encourage exploration, behavior that is central to how the DeweyBrowser was designed to be used
  • The DeweyBrowser is an example of an entire application built using AJAX

8. 9. Curiouser

  • Curiouser is an approach to making the best use of data about items in WorldCat and a user interface for exploring and selecting works and items
  • The prototype interface
    • employs the OCLC FRBR work-set algorithm
    • exploits structured data in bibliographic, authority, and holdings records,
    • integrates techniques from FictionFinder for display and navigation of records in a FRBR context,
    • explores Web services and other data sources to enhance the utility of Open WorldCat

10. OCLC FRBR Work-Set Algorithm

  • A work set is a group of bibliographic records with the same Author/Title key
  • A key is generated for each bibliographic record
  • Variant forms of names and titles are converted to established forms based on the OCLC authority file
  • Keys are sorted and compared to form work sets
