- Content
- The aim of this study is to develop a software tool, VisuaLCSH, for effective searching, browsing, and maintenance of LCSH. This tool enables visualizing subject headings and hierarchical structures implied and embedded in LCSH. A conceptual framework for converting the hierarchical structure of headings in LCSH to an explicit tree structure is proposed, described, and implemented. The highlights of VisuaLCSH are summarized below: 1) revealing multiple aspects of a heading; 2) normalizing the hierarchical relationships in LCSH; 3) showing multi-level hierarchies in LCSH sub-trees; 4) improving the navigational function of LCSH in retrieval; and 5) enabling the implementation of generic search, i.e., the 'exploding' feature, in searching LCSH.

- Die zunehmende Nutzung der DDC im deutschsprachigen Raum wird in den kommenden Jahren in der bibliothekarischen Ausbildung und Praxis zu einer stärkeren Nachfrage nach Informations- und Unterrichtsmaterialien zu dieser Klassifikation führen. Die deutsche Übersetzung des DDC-Lehrbuchs Dewey Decimal Classification: Principles and Application bietet für Studierende und praktisch mit dem DDC-Klassifizieren und -Recherchieren Arbeitende eine umfassende Einführung in die theoretischen Grundlagen der Klassifikation, ergänzt durch fachliche Aspekte und viele Einzelbeispiele. Der Gebrauch der Hilfstafeln und die Notationssynthesezwei wesentliche Elemente der DDC - werden detailliert erläutert und mit praktischen Übungen vertieft.

- Abstract
- Zu den großen Herausforderungen einer sinnvollen Suche im WWW gehören die riesige Menge des Verfügbaren und die Sparchbarrieren. Verfahren, die die Web-Ressourcen im Hinblick auf ein effizienteres Retrieval inhaltlich strukturieren, werden daher ebenso dringend benötigt wie Programme, die mit der Sprachvielfalt umgehen können. Im folgenden Vortrag werden wir einige Ansätze diskutieren, die zur Bewältigung der beiden Probleme derzeit unternommen werden
