- Abstract
- Das Passagen-Retrieval erlaubt explorierendes Navigieren in Volltextdatenbanken, aber auch in textorientierten Hypertextbasen. Es wird experimentell an fünf, im Information Retrieval geläufigen Assoziationskoeffizienten überprüft, inwieweit mit ihnen Textpassagen, gewonnen aus der Konversion von Absätzen aus einer Buchvorlage (Hypertextbuch von R. Kuhlen, 1991b), automatisch verknüpft werden können. Voraussetzung für die Anwendung der Maße ist eine Volltextinvertierung mit linguistisch abgesicherter Stammformenreduktion. Die Ergebnisse, gewonnen aus der Bewertung der Verknüpfungsangebote entsprechend den Berechnungen nach den fünf Koeffizienten und aus dem Vergleich mit einer intellektuellen Verknüpfungsvorgabe, zeigen eine deutliche Präferenz zugunsten des Asymmetrie-Maßes, das vielleicht noch durch eine Kombination mit dem Cosinus-Maß verbessert werden könnte. Die automatisch erstellten Verknüpfungsangebote sind sowohl im Autoren-Modus zur Unterstützung des Aufbaus von Hypertextbasen sinnvoll als auch im Lese-Modus als Möglichkeit des assoziativen Navigierens in großen Hypertextbasen verwendbar.

- Abstract
- Der Artikel stellt Ergebnisse einer Studie zur vergleichenden Bewertung von Verfahren der nachfrageorientierten Inhaltserschließung im Volltextarchiv der Stuttgarter Zeitung vor. Im ersten Teil der Arbeit wird empirisch untersucht, ob in der digitalen Pressedokumentation auf eine intellektuelle Indexierung von Artikeln verzichtet werden kann, wenn ausschließlich im Volltext recherchiert wird. Im zweiten Teil der Arbeit werden Möglichkeiten und Grenzen einer innovativen Inhaltserschließung von Volltexten in der Textdokumentation der Stuttgarter Zeitung mittels Digitaler Textdossiers diskutiert

- Abstract
- Die bibliothekarische Informationserschließung war unist bislang durch den OPAC geprägt, der im wesentlichen die Monographien und Zeitschriften einer Bibliothek erschließt. Es werden 2 neue Bereiche skizziert, die in Zukunft ebenfalls Teil der bibliothekarischen Informationserschließung sein können und werden: die Erschließung unselbständiger Literatur und der Einsatz automatisierter 'reference and information services'. Im ersten Fall ist die Entwicklung bereits weit vorangeschritten, Verbundsysteme und Library Suppliers bieten bereits Inhaltsdaten von Zeitschriften als Fremdleistung an. Im zweiten Fall ist die Entwicklung, vor allem im angloamerikanischen Raum, noch - trotz zahlreicher Projekte - in den Anfängen. Der Einsatz wissensbasierter Systeme in diesem Bereich macht die Aufgaben hier besonders komplex, biete zugleich aber hanz neue Lösungsmöglichkeiten an, wie am Beispiel einiger amerikanischer Projekte dokumentiert wird. Wesentlich ist, daß Informationserschließungssysteme, wie sie ansatzweise im Internet bereits eingesetzt werden, den gesamten bereich elektronischer wie herkömmlicher Information umfassen, um einen allgemeinen und umfassenden Einstieg für den Informationssuchenden zu bieten

- Abstract
- Dieser Artikel diskutiert die "sieben Todsünden" der Volltextrecherche und macht sowohl praktische als auch utopische Vorschläge zu ihrer Überwindung. Zunächst wird versucht, die persönlichen "sieben Sünden" auf einer Standardliste zu verzeichnen. Je nachdem, welches Standardwerk man zu Rate zieht, kommen hierbei einige interessante Abweichungen vor. Selbst der Thesaurus von WordPerfect zeigt auf die Frage nach "Sünde" hilfsbereit alle sieben! Ein Beispiel für "Stolz" ist das Online-System, für das in ganzseitigen Anzeigen in großen nationalen Publikationen erklärt wird: 'Unser Angebot ist eine Welt von Informationen auf Knopfdruck'. "Gier" ist das Downloading von Volltexten, "Trägheit" die langsame Verarbeitungszeit: "Geiz" hat etwas mit der Preisgestaltung zu tun, und alles liegt irgendwo zwischen "Lust" und "Ärger"; c'est la vie, n'est-ce pas?

- Abstract
- 10 Jahre cogito lassen auch uns auf diesen in der Branche langen Zeitraum zurückblicken. Der Informationsmarkt 1985 war noch gut überschaubar und von der PSI noch gar nicht als attraktiv erkannt. Doch schon zu diesem Zeitpunkt machten wir uns Gedanken über die Verarbeitung von unstrukturierten Informationen, da mehrere Nachrichtenverteilsysteme für größere Behörden relalisiert wurden. Die Wünsche der Benutzer waren mit herkömmlichen Datenbanken nur schwer zu realisieren oder die Zugriffszeiten zu lang

- Abstract
- Information research using keywords is largely ignored by readers but in medium sized libraries such as that of the City of Science and Industry (Paris), with a multimedia collection of some 200.000 documents, it is the most effective tool. The reader, however, needs guidance in using this technique, and in refining searches to reduce noise. Examples are given demonstrating how keyword searches can identify non-indexed material, documents in other languages, and collective authors

- Abstract
- Describes SIFT (Search in Free Text) an information retrieval system originally developed for administering governmental documents in Norway but which is now being applied alsewhere. SIFT handles structured information well. A library system, SIFT-BIBL, is now available. SIFT's retrieval engine and search facilities are powerful. Its user interface is limited but being imporved. An application programmer interface has been released which will allow programmers to develop their own interface. A Windows-based- client-server version is now being beta tested

It may not be the job of the library professionals to design and develop the hypermedia system for information retrieval, but their ideas and experience will play an important role
