    Abstract
    Es werden die Grundprobleme der Sacherschließung in Online-Katalogen dargestellt. Ein anschließendes Kapitel behandelt das Verhältnis von verbaler und klassifikatorischer Erschließung. Ein wichtiger Teil der Aussagen betrifft das Gebiet der verbalen Sacherschließung und damit das nationale Regelwerk: Es werden Vorschläge für eine Reform der RSWK im Hinblick auf die Erfordernisse der OPAC unterbreitet. Regelwerk und Normdatei (SWD) bilden dabei eine Einheit und werden zusammen betrachtet. Im vergangenen Jahr wurden die Ergebnisse der Expertengruppe mit dem Schwerpunkt Formalerschließung vorgelegt, nun folgen die Aussagen zur Sacherschließung, welche die Expertengruppe - in veränderter personeller Zusammensetzung unter Leitung von Dr. Friedrich Geißelmann, Regensburg - erarbeitet hat. Die bibliothekarische Öffentlichkeit ist aufgefordert, sich dazu bis zum Jahresende zu äußern. Beide Berichte beziehen sich aufeinander und versuchen, den Zusammenhang zwischen Formal- und Sacherschließung herzustellen. Vom gegenwärtigen Stand der Sacherschließung in deutschen Bibliotheken ausgehend - wozu auch durch die Gruppe im Frühjahr 1993 eine Umfrage in wissenschaftlichen und Öffentlichen Bibliotheken gemacht worden ist, werden die Grundprobleme der Sacherschließung in Online-Katalogen dargestellt. Ein anschließendes Kapitel behandelt das Verhältnis von verbaler und klassifikatorischer Erschließung. Ein wichtiger Teil der Aussagen betrifft das Gebiet der verbalen Sacherschließung und damit das nationale Regelwerk: Es werden Vorschläge für ein Reform der RSWK im Hinblick auf die Erfordernisse des OPAC unterbreitet. Regelwerk und Normdatei (SWD) bilden dabei eine Einheit und werden zusammen betrachtet. Es geht um Kettenbildung und Permutationsregeln, Kompositumbildung oder Zerlegung von Begriffen, Pleonasmus, Funktion der SWD, Ansetzung von Schlagwörtern, die Einführung eines Zeit-Codes, Erschließung literarischer Formen und Gattungen, den verwendeten Zeichensatz, den Umgang mit Verweisungen

    Abstract
    Most indexed databases now include their thesauri and/or coding in their bibliographic files, searchable at the databases' online connect rates. Assesses the searchability of these on the different hosts. Thesauri and classifications are also available as diskette or CD-ROM products. Describes a number of these, highlighting the diskette thesaurus from IFI/Plenum Data for its flexible databases, the CLAIMS Uniterm and Comprehensive indexes to US chemical patents

    Abstract
    In der vorliegenden Form können die RSWK nicht befriedigen. Die geforderte hochdifferenzierte Erschließung ist in einem OPAC wegen der vielfältigen Abfragemöglichkeiten gar nicht nötig, ja eine einheitliche Indexierung und effiziente Suche is aufgrund der komplexen Regeln sogar erschwert. Aufgaben und Probleme der verbalen Sacherschließung in OPACs werden in dieser Arbeit aufgezeigt und Ansätze zu einer Alternative diskutiert. Der traditionelle Indexkatalog hat als Ergänzung des modernen Information Retrieval nur eine Zukunft, wenn die Möglichkeiten der EDV und der Faktor Mensch bei der Regelwerkentwicklung besser berücksichtigt werden

    Abstract
    Despite early claims to the contemporary, thesauri continue to find use as access tools for information in the full-text environment. Their mode of use is changing, but this change actually represents an expansion rather than a contrdiction of their utility. Thesauri and similar vocabulary tools can complement full-text access by aiding users in focusing their searches, by supplementing the linguistic analysis of the text search engine, and even by serving as one of the tools used by the linguistic engine for its analysis. While human indexing contunues to be used for many databases, the trend is to increase the use of machine aids for this purpose. All machine-aided indexing (MAI) systems rely on thesauri as the basis for term selection. In the 21st century, the balance of effort between human and machine will change at both input and output, but thesauri will continue to play an important role for the foreseeable future

    Abstract
    Information or Document Retrieval is the subject of this book. It is not an introductory book, although it is self-contained in the sense that it is not necessary to have a background in the theory or practice of Information Retrieval in order to understand its arguments. The book presents, as clearly as possible, one particular perspective on Information Retrieval, and attempts to say that certain aspects of the theory or practice of the management of documents are more important than others. The majority of Information Retrieval research has been aimed at the more experimentally tractable small-scale systems, and although much of that work has added greatly to our understanding of Information Retrieval it is becoming increasingly apparent that retrieval systems with large data bases of documents are a fundamentally different genre of systems than small-scale systems. If this is so, which is the thesis of this book, then we must now study large information retrieval systems with the same rigor and intensity that we once studied small-scale systems. Hegel observed that the quantitative growth of any system caused qualitative changes to take place in its structure and processes.

    Abstract
    Die Diskussion um Vor- und Nachteile von Präkoordination oder Postkoordination wird unter den in der verbalen Sacherschließung Engagierten in Deutschland seit Jahren geführt. Mit zunehmender Verbreitung der RSWK gewinnen die Überlegungen, die sich angesichts der Ausbreitung des OPAC für das 'Zerschlagen' der Schlagwortketten aussprechen, an Bedeutung. In diesem Zusammenhang trägt eine Berücksichtigung der internationalen Debatte um Prä- und Postkoordination zur Erweiterung des nationalen Horizontes bei. Der Beitrag ist eine leicht gekürzte Übersetzung eines Referates, das die Autorin beim IFLA Satellite Meeting zum Thema 'Subject indexing in the 90's - principles and practices' im August 1993 in Lissabon gehalten hat

    Abstract
    Vorsatz zum Sinn von Normdateien: "Die sachgerechte Nutzung von Normdateien erfordert eine ausgeklügelte Datenbankstruktur, über die sich Bibliothekare und Informatiker offensichtlich erst noch verständigen müssen"; Hauptsatz zur Redundanz von P,T,G,C,K,Z,F - verbale Sacherschließung als Funktion: "Außer den Sachschlagwörtern können alle anderen Schlagwortkategorien der RSWK/SWD 'eingespart', auf die Einrichtung eigener Schlagwortkettenfelder in den Titelaufnahmen kann verzichtet werden: Nachsatz zur 'Kombinatorik': "An die Stelle von Schlagwortketten würden Chiffren für Verknüpfungskombinationen ('Kombinationsmuster') treten, die auch im Sinne von Steuerungsinstrumenten zu nutzen wären"

    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
    Subject access in library OPACs might be improved for some users by taking advantage of all of the hierarchical relationships which are indicated on existing LCSH entries. Recommends that cross references pointing to broader terms be displayed, in addition to those for narrower and related terms to which users have traditionally benn directed. Traces the old practice back to Charles Cutter, reports on deliberations of the ALCTS Subject Analysis Committee nearly 120 years later. Discusses practical concerns related to implementing the change, including the accuracy of hierarchical relationships in the LCSH system and possible techniques for using the MARC format to generate the cross references

    Abstract
    Open system protocols for search and retrieval have not provided explicit ways in which to implement thesaurus-aided searching. A number of different approaches within the existing protocols, as well as a proposed service, are evaluated. A general approach to implementing thesaurus-aided searching, particularly during consultation of a thesaurus, requires an entirely new service, whose main features are described

    Abstract
    Reports an algorithmic approach to the automatic generation of thesauri for electronic community systems. The techniques used included terms filtering, automatic indexing, and cluster analysis. The testbed for the research was the Worm Community System, which contains a comprehensive library of specialized community data and literature, currently in use by molecular biologists who study the nematode worm. The resulting worm thesaurus included 2709 researchers' names, 798 gene names, 20 experimental methods, and 4302 subject descriptors. On average, each term had about 90 weighted neighbouring terms indicating relevant concepts. The thesaurus was developed as an online search aide. Tests the worm thesaurus in an experiment with 6 worm researchers of varying degrees of expertise and background. The experiment showed that the thesaurus was an excellent 'memory jogging' device and that it supported learning and serendipitous browsing. Despite some occurrences of obvious noise, the system was useful in suggesting relevant concepts for the researchers' queries and it helped improve concept recall. With a simple browsing interface, an automatic thesaurus can become a useful tool for online search and can assist researchers in exploring and traversing a dynamic and complex electronic community system
