- Abstract
- Der Beitrag beschäftigt sich mit der Anwendung eines Verfahrens zur Automatischen Indexierung von Titeldaten in Bibliotheken. Die Arbeitsweise des Verfahrens und seine Nutzung innerhalb des von der Deutschen Forschungsgemeinschaft geförderten und an der Universitäts- und Landesbibliothek Düsseldorf durchgeführten Projekts MILOS werden geschildert. Die Ergebnisse eines Retrievaltests belegen die Tauglichkeit des Verfahrens für den Einsatz in Bibliotheken. Aufbauend auf diesen Ergebnissen werden Perspektiven für eine sinnvolle Verbindung von konventioneller bibliothekarischer Sacherschließung und automatischen Verfahren entworfen

- Abstract
- "So haben wir inzwischen einen Stand der Diskussion erreicht, bei dem zwschen den Anforderungen an das, was Bibliotheken leisten sollten und dem, worüber Bibliothekare reden, eine immense Lücke klafft. Der Bericht der Expertengruppe Online-Kataloge ist dafür nur ein weiteres, leider trauriges Beispiel. Er ist aber auch - dies ist besonders zu bedauern - eine verpaßte Chance, denn hier hätte sich die ideale Gelegenheit geboten, für die neue Katalogform OPAC auch neue Möglichkeiten der Sacherschließung zu diskutieren. Da dies nicht geschehen ist, bleibt nur zu hoffen, daß unter dem sicher stärker werdenden Druck der Benutzer auf die Bibliotheken und deren Informationsangebot auch begonnen wird, offen über die bislang 'heilige Kuh' RSWK zu rden"

- Abstract
- Sachliche Suchen in bibliothekarischen Online-Katalogen enden häufig mit unbefriedigenden Ergebnissen. Als eine Ursache dafür kann angesehen werden, daß die Gestaltung des Suchprozesses das semantische Umfeld einer Suchanfrage nicht mit einbezieht, daß in Übertragung der Verhältnisse in konventionellen Katalogen am Paradigma des Wort-Matching zwischen Suchwort und Indexat festgehalten wird. Es wird statt dessen das Konzept einer semantischen Umfeldsuche entwickelt und gezeigt, welche Rolle die Verwendung strukturierten Vokabulars dafür spielen kann. Insbesondere wird dargestellt, welche Möglichkeiten Verfahren der wörterbuchgestützten maschinellen Indexierung in diesem Zusammenhang spielen können. Die Ausführungen werden durch Beispiele illustriert

- Abstract
- Examines the effectiveness of automated indexing and presents the results of a study of information retrieval from a segment (40.000 items) of the ULB Düsseldorf database. The segment was selected randomly and all the documents included were indexed automatically. The search topics included 50 subject areas ranging from economic growth to alternative energy sources. While there were 876 relevant documents in the database segment for each of the 50 search topics, the recall ranged from 1 to 244 references, with the average being 17.52 documents per topic. Therefore it seems that, in the immediate future, automatic indexing should be used in combination with intellectual indexing
