Advances in Knowledge Organization: Embracing New Technologies for Digital Access

This document discusses the evolving landscape of knowledge organization (KO) in libraries, emphasizing the need for traditional methods to adapt and integrate with new technologies. It highlights emerging computational, text-based search techniques and web services that enhance access to bibliographic information. The paper outlines the use of automated tools for record creation, citation indexing, and authority control in relation to digital documents. The goal is to improve record quality and accessibility while exploring the roles of classification schemes, subject headings, and collaborative filtering methods in modern information retrieval.

  1. What is this about … developments in characterizing subjects Diane Vizine-Goetz Research Scientist OCLC

  2. Challenge • Traditional library methods must compete with new approaches for accessing content • Computational, text-based search techniques • Foundation of most Web search engines • Systems that exploit the opinions and actions of individuals & communities • Citation indexing, recommendation systems, collaborative filtering techniques, etc. See Clifford Lynch, The New Context for Bibliographic Control In the New Millennium

  3. Challenge • Methods effective for print, unlikely to be the same techniques used for digital documents • Need to determine role of knowledge organization (KO) resources in relation to new approaches • Authority files • Subject heading systems and thesauri • Classification schemes

  4. KO resources are currently embedded in systems & services • OCLC Connexion • Provides access to several KO schemes & links among schemes • Dewey, LCSH, Name authorities • Automated application tools • Harvest & record creation • Classification • Control of names, subjects, class numbers

  5. Dewey in OCLC Connexion

  6. DDC with associated Library of Congress Subject Headings

  7. Automated tools create records & assign class numbers

  8. Auto-generated record with DDC

  9. Automated checking of names & subjects

  10. Need more flexible, modular knowledge organization services • CURL librarians wish list • Automatically check name and subject authorities • Automatically supply Dewey Decimal Classification numbers based on subject entries • On-demand check of subject and name authorities in non-OCLC record sources • Authorities notification service • Improve record quality/completeness

  11. Emerging technologies provide opportunities for new services • Tools and features previously available only in integrated systems can now be provided as 'web services' • “network accessible application components” • “interoperable building blocks for constructing applications” • “self-describing applications that can be discovered and accessed over the web by other applications” • Technical definition • Web Services are a suite of protocols that define how requests and responses between software applications should be encoded & transferred over the web

  12. Knowledge Organization Services • Record Enrichment • Classes • Subjects • Names • Summaries KO Schemes 635.951 • Classification • Auto-class • Number verification • Captions • Associated Terms • Updates • Authority Control • Auto-assign • Name/Subject validation • Associated Classes • Authorities notification Name Authority Files DDC LCSH

  13. OCLC Web Services Demo Rare and endangered animals Rare and endangered species

  14. Amazon Web Services Demos • http://www.php9.com/amazon.php • http://www.kokogiak.com/amazon/ • http://www.buildafrica.org/music.php

  15. Record enhancement

  16. Prototypes & Demonstration projects • Prototype • LCCN Web Service Demo (previous slide) • OCLC & Northwestern University • DDC number verification for Cataloger's Toolkit for Voyager ILS • eprints-UK • OCLC will supply subject descriptions & name authorities as Web services for harvested resources
