- Abstract
- Es wird ein Verfahren zum Vergelich von Klassifikationen vorgestellt. Es gestattet, die Abweichungen zwischen zwei Klassifikationen zu lokalisieren und erleichtert so die intellektuelle Kontrolle. Das Verfahren ist als Baustein des Systems FAKYR implementiert. Es wird auf Klassifikationen angeandt, die durch graphentheoretische Verfahren entstanden sind. Zunächst wird gezeigt, wie die Veränderung des Schnittes das Klassifikationsergebnis beeinflußt, anschließend wird das Vergleichsverfahren bei der automatischen Erstellung zweisprachiger Termklassen benutzt

- Abstract
- In der bibliothekarischen Welt sind die Vorzüge einer klassifikatorischen Inhaltserschließung seit jeher wohlbekannt. Auch im Zeitalter der Online-Kataloge gibt es dafür keinen wirklichen Ersatz, da - kurz formuliert - ein stichwortbasiertes Retrieval alleine mit Problemen wie Ambiguität und Mehrsprachigkeit nicht fertig zu werden vermag. Zahlreiche Online-Kataloge weisen daher Notationen verschiedener Klassifikationssysteme auf; allerdings sind die darauf basierenden Abfragemöglichkeiten meist noch arg unterentwickelt. Viele Datensätze in OPACs sind aber überhaupt nicht sachlich erschlossen, sei es, dass sie aus retrospektiv konvertierten Nominalkatalogen stammen, sei es, dass ein Mangel an personellen Ressourcen ihre inhaltliche Erschließung verhindert hat. Angesichts großer Mengen solcher Datensätze liegt ein Interesse an automatischen Verfahren zur Sacherschließung durchaus nahe.

- 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

- Abstract
- Beim Clustering werden Dokumente aufgrund von Ähnlichkeiten untereinander klassifiziert, im Gegensatz z.B. zur Klassifikation anhand einer Ontologie. Bei den gebräuchlichen Clusteringverfahren wird ein Dokument als die Menge seiner Wörter angesehen. Zur Bestimmung der Ähnlichkeit zwischen Dokumenten werden verschiedene Ähnlichkeitsmaße definiert.
