OCLC Research Terminology Services Project

• Goals
• Provide access to controlled vocabularies and
  other knowledge organization schemes through Web
  services
• Develop prototype services that can be accessed
  by library and Semantic Web applications

3
Initial focus on genre vocabularies

• Available
• DCMI Type Vocabulary
• Genre Terms from Guidelines on Subject Access to
  Individual Works of Fiction, Drama, etc. (GSAFD)
• Newspaper Genre Terms (NGL)
• Under development
• Radio Form/Genre Terms (RADFG)
• U.S. Library of Congress
• Moving Image Form/Genre Terms (MIGFG)

• Medical Subject Headings (MeSH)
• U.S. National Library of Medicine 2005 MeSH
  2005 MeSH sample
• Répertoire de vedettes-matière (RVM)
• Bibliothèque de l'Université Laval

5
Processing workflow

• Convert files to standard format
• MARC 21 authorities or classification formats
• Enhance records with administrative data
• As feasible, enrich with mappings to other
  vocabularies
• Convert file into XML format (MARC XML)
• Load into services environment
• Supports various web services

Microsoft Research Pane

• Part of MS Office 2003 installation
• Provides a convenient means for users of Internet
  Explorer and MS Office 2003 applications to have
  access to loosely-coupled services from 3rd
  parties
• Examples
• Access to 3rd party reference databases (e.g.,
  articles)

OCLC services pilot test

• OCLC production group evaluating for possible
  terminology services products
• Initial testing using Microsoft Research Pane
  together with OCLC Connexion interface
• Offers access to multiple controlled vocabularies
  to support consistent metadata for library,
  archives, museum collections
• Pilot institutions include U.S. non-U.S.
  public, special and university libraries, and
  non-library organizations

19
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)

20
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

21
DeweyBrowser

• The interface presents search results at three
  levels corresponding to 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

22
Dewey Browser

• 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

23
Dewey Browser

• 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
