- Abstract
- Kooperative Katalogisierung in der Bibliotheksverbünden und steigende Zahlen retrokonvertierter Altdaten füfhren zu einem stetigen Anwachsen maschinenlesbar verfügbarer Titeldaten. Dieser Entewicklung aud ser Katalogisat- bzw. Datenseite entspricht eine ähnlich rasante Entwicklung auf der Seite der Zugangsmöglichkeiten, den Online-Publikumskatalogen. Immer mehr Katalogdaten von immer mehr Bibliotheken sind in immer mehr OPACs nachgewiesen. Mit dieser auch durch neue Zugriffsformen (Internet) verbesserten Verfügbarkeit hält die bibliothekarische Sacherschließung längst nicht mehr Schritt. In diesem Beitrag werden die Vorgehensweise und Ergebnisse des Projektes MILOS I vorgestellt, das an der Universitäts- und Landesbibliothek zur automatischen Indexierung bibliothekarischer Titeldaten und zur Anreicherung von Katalogdaten durchgeführt wurde.

- 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

- 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
- "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
- 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
- Das Internet wird immer unübersichtlicher - auch eine Binsenweisheit, aber wohl mehr ein handfestes Problem. Abhilfe versprechen die diversen Suchmaschinen und Verzeichnisse der kommerziellen Anbieter, zu denen sich thematische Link-Sammlungen anderer Institutionen - etwas Bibliotheken - gesellen. Während die Suchmaschinen mit dem Anspruch arbeiten, das gesamte Netz zu erschließen (und diesen damit einlösen, daß sie ihre Kundschaft teilweise mit mehreren hundert Treffern nach einer Anfrage konfrontieren), haben die Anbieter ausgewählter und intellektuelle erschlossener Quellen häufig mit dem Problem mangelnder Aktualität und der Beschränktheit ihres Angebots zu kämpfen. - Der folgende Beitrag diskutiert verschiedene Verfahren, die in erheblich stärkerem Maße sowohl die Vollständigkeit als auch die Relevanz der durchsuchten beziehungsweise gefundenen Internetquellen sicherstellen sollen. In diesem Zusammenhang wird auch die Frage erörtert, welche Rolle den Bibliotheken bei der Entwicklung und Anwendung solcher Techniken zukommen könnte
