- Abstract
- This paper discusses two inter-related themes: the retrieval potential of faceted thesauri and XML representations of fundamental facets. Initial findings are discussed from the ongoing 'FACET' project, in collaboration with the National Museum of Science and Industry. The work discussed seeks to take advantage of the structure afforded by faceted systems for multi-term queries and flexible matching, focusing in this paper an the Art and Architecture Thesaurus. A multi-term matching function yields ranked results with partial matches via semantic term expansion, based an a measure of distance over the semantic index space formed by thesaurus relationships. Our intention is to drive the system from general representations and a common query structure and interface. To this end, we are developing an XML representation based an work by the Classification Research Group an fundamental facets or categories. The XML representation maps categories to particular thesauri and hierarchies. The system interface, which is configured by the mapping, incorporates a thesaurus browser with navigation history together with a term search facility and drag and drop query builder.

- Abstract
- New forms of man-machine interaction are becoming available that have great power for the delivery of information. But the scales of speed and capacity on which the computing machines operate demand new thoughts as to how information can be stored and retrieved. The objective of the discussion in this paper is to argue for a combination of natural-language processing and subject classification to be able to meet the demands

- Abstract
- Die Dewey-Dezimalklassifikation (DDC) ist ein mächtiges Instrument der klassifikatorischen Inhaltserschließung. Immer mehr Bibliotheken im In- und Ausland erkennen den Nutzen der international am weitesten verbreiteten Universalklassifikation. Die Deutsche Nationalbibliothek (DNB) setzt die DDC seit 2006 für die inhaltliche Erschließung der Bibliografiereihen A, B und H ein. Seitdem wurden rund 800.000 Publikationen mit DDC-Notationen versehen. Der Nutzen von Klassifikationen ist unter Bibliothekar/innen unumstritten. Die Bibliotheksnutzer/innen hingegen wissen oft nicht, dass der Katalog ihrer Bibliothek auch eine systematische Recherche ermöglicht. Ihre Recherchestrategie ist meist verbal. Durch Internetsuchmaschinen wird diese Strategie noch bestärkt. Daher liegt es nahe, auch für die klassifikatorisch erschlossenen Titel einen verbalen Sucheinstieg zu schaffen. ie DDC enthält nicht nur die in vielen Klassifikationssystemen üblichen Registereinträge und Klassenbenennungen, sondern auch die im Rahmen des Projekts CrissCross in großem Umfang erstellten Verknüpfungen zu Schlagwörtern der Gemeinsamen Normdatei (GND), die für diesen Zweck ausgewertet werden können.
