    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
    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
    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
    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
    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

    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
    Describes a typical traditional 1989 free text system and discusses developments in data storage, in search strategy and in the storage and retrieval of real time data. Outlines the following areas in which free text systems are likely to develop: standards; integration; dynamic data exchange; improved user interfaces; and better retrieval methods

    Abstract
    Discusses the introduction of hypermedia in information delivery and its advantages. Describes the special features in the design of full text databases and steps in developing in-house hypermedia databases. 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

    Abstract
    Reviews developments in full text databases in 1995. Numbers of full text databases have increased by 12%. Consumer services are offering more full text databases, as is the Internet. News feeds are increasingly being offered to corporate users. Contemplates the ideal information service and how full text databases could evolve in this environment

    Abstract
    In this article, the fourth in a series on microcomputer software for information storage and retrieval, test results of six indexing and full-text retrieval programs are presented and various properties and qualities of these programs are discussed. The common faeture of programs in these categories is that they are primarily meant to retrieve words (or combination of them) in large text files. To do this they either simply index existing text files in one or more formats (indexing programs), or they store and index them in their own database format (full-text retrieval programs). The programs reviewed in this issue are the indexing programs Ask-it, Texplore and ZYindex and the full-text retrieval programs KAware, textMaster and WordCruncher. All programs run under MS-DOS. In addition ZYindex has a Windows and a Unix version and TextMaster is also available for for Unix. For each of the six programs almost 100 facts and test results are tabulated. The programs are also discussed individually

    Abstract
    Homonymy is known to often cause false drops in free text searching in a full text database. The problem is quite common and difficult to avoid in Finnish, but nobody has examined it before. Reports on a study that examined the frequency of, and solutions to, the homonymy problem, based on searches made in a Finnish full text database containing about 55.000 newspaper articles. The results indicate that homonymy is not a very serious problem in full text searching, with only about 1 search result set out of 4 containing false drops caused by homonymy. Several other reasons for nonrelevance were much more common. However, in some set results there were a considerable number of homonymy errors, so the number seems to be very random. A study was also made into whether homonyms can be disambiguated by syntactic analysis. The result was that 75,2% of homonyms were disambiguated by this method. Verb homonyms were considerably easier to disambiguate than substantives. Although homonymy is not a very big problem it could perhaps easily be eliminated if there was a suitable syntactic analyzer in the IR system
