• How Can Classificatory Structures Be Used to Improve Science Education?

      Buchel, Olha; Coleman, Anita Sundaram; Budd, John (2003-01)
      There is increasing evidence that libraries, traditional and digital, must support learning, especially the acquisition and enhancement of scientific reasoning skills. This paper discusses how classificatory structures, such as a faceted thesaurus, can be enhancedfor novice science learning. Physical geography is used as the domain discipline, and the Alexandria Digital Earth Prototype project provides the test bed for instructional materials and user analyses. The use of concept maps and topic maps for developing digital learning spaces is briefly discussed.
    • Treatment of Georeferencing in Knowledge Organization Systems: North American Contributions to Integrated Georeferencing

      Buchel, Olha; Hill, Linda L.; Jacob, Elin K.; Kwasnik, Barbara (2009)
      Recent research projects in North America that have advanced the integration of formal mathematical georeferencing and informal placename georeferencing in knowledge organization systems are described and related to visualization applications.
    • Uncovering Hidden Clues about Geographic Visualization in LCC

      Buchel, Olha; Budin, Gerhard; Swertz, Christian (Ergon-Verlag, 2006)
      Geospatial information technologies revolutionize the way we have traditionally approached navigation and browsing in information systems. Colorful graphics, statistical summaries, geospatial relationships of underlying collections make them attractive for text retrieval systems. This paper examines the nature of georeferenced information in academic library catalogs organized according to the Library of Congress Classification (LCC) with the goal of understanding their implications for geovisualization of library collections.
