    Abstract
    The second edition of the Bibliographic Classidication of H.E. Bliss (BC2), being prepared under the editorship of Jack Mills, Vanda Broughton and others, is a rich source of structure and terminology for thesauri covering different subject fields. The new edition employs facet analysis and is thesaurus-compatible. A number of facet-based thesauri have drawn upon Bliss for terms and relationships. In two of these thesauri the Bliss Classification was the source of both systematic and alphabetical displays. The DHSS-DATA thesaurus, published by the United Kingdom Department of Health and Social Security, provides controlled terms and Bliss class numbers for indexing and searching the DHSS-DATA database. The ECOT thesaurus (Educational courses and occupations thesaurus) prepared for the Department of Education and Science, uses the software sedigned for the British Standards Institution ROOT thesaurus to genearte an alphabetical display from the systematic display derived from the Bliss schedules. Problems, benefits, and future prospects of Bliss-based thesaurus construction are discussed

    Abstract
    Henry Evelyn Bliss (1870-1955) devoted several decades of his life to the study of classification and the development of the Bibliographic Classification scheme while serving as a librarian in the College of the City of New York. In the course of the development of the Bibliographic Classification, Bliss developed a body of classification theory published in a number of articles and books, among which the best known are The Organization of Knowledge and the System of the Sciences (1929), Organization of Knowledge in Libraries and the Subject Approach to Books (1933; 2nd ed., 1939), and the lengthy preface to A Bibliographic Classification (Volumes 1-2, 1940; 2nd ed., 1952). In developing the Bibliographic Classification, Bliss carefully established its philosophical and theoretical basis, more so than was attempted by the makers of other classification schemes, with the possible exception of S. R. Ranganathan (q.v.) and his Colon Classification. The basic principles established by Bliss for the Bibliographic Classification are: consensus, collocation of related subjects, subordination of special to general and gradation in specialty, and the relativity of classes and of classification (hence alternative location and alternative treatment). In the preface to the schedules of A Bibliographic Classification, Bliss spells out the general principles of classification as weIl as principles specifically related to his scheme. The first volume of the schedules appeared in 1940. In 1952, he issued a second edition of the volume with a rewritten preface, from which the following excerpt is taken, and with the addition of a "Concise Synopsis," which is also included here to illustrate the principles of classificatory structure. In the excerpt reprinted below, Bliss discusses the correlation between classes, concepts, and terms, as weIl as the hierarchical structure basic to his classification scheme. In his discussion of cross-classification, Bliss recognizes the "polydimensional" nature of classification and the difficulties inherent in the two-dimensional approach which is characteristic of linear classification. This is one of the earliest works in which the multidimensional nature of classification is recognized. The Bibliographic Classification did not meet with great success in the United States because the Dewey Decimal Classification and the Library of Congress Classification were already weIl ensconced in American libraries by then. Nonetheless, it attracted considerable attention in the British Commonwealth and elsewhere in the world. A committee was formed in Britain which later became the Bliss Classification Association. A faceted edition of the scheme has been in preparation under the direction of J. Mills and V. Broughton. Several parts of this new edition, entitled Bliss Bibliographic Classification, have been published.

    Abstract
    Auf der Ebene der Systemfunktionalität werden konventionelle Dokument-Retrieval-Systeme und Fakten-Retrieval-Systeme mit Expertensystemen verglichen. Anhand eines juristischen Informationsproblems und exemplarischer Interaktion zwischen Benutzer und System werden die verfügbaren Wissensquellen jedes Systemtyps sowie notwendiges Hintergrundwissen der Systembenutzer rekonstruiert. Das Problemlösungsvermögen von Expertensystemen wird am Beispiel deduktiver Schlußfolgerungsoperationen auf einer juristischen Regelbasis illustriert. Die Gegenüberstellung der auf diese Weise abgeleiteten Merkmale von konventionellen und intelligenten Informationssystemen wird durch eine Einschätzung der Auswirkungen ergänzt, die Information-Retrieval-Experten-Systeme auf die Informationspraxis haben können

    Abstract
    Semantische Repräsentationssprachen (SRL) dienen der strukturierten Darstellung und Handhabung von Wissen. Dieses Wissen, das durch die menschliche Sprache vermittelt und in Informationssystemen bereitgestellt werden soll, muß benutzergerecht strukturiert werden, um ein Wiederauffinden effektiv und effizient zu gewährleisten. Um diesen Zusammenhang zwischen dem syntaktischen Aufbau einer SRL und der Systemleistung fundiert untersuchen zu können, sind Beschreibungskonzepte erforderlich, mit denen sich die relevanten Aspekte von SRL und deren Einfluß auf eine Retrievalumgebung hinreichend exakt darstellen lassen. Im vorliegenden Beitrag wird ein solches Beschreibungsmodell vorgestellt

    Abstract
    In dieser Arbeit wird der Versuch unternommen, die beiden klassischen Typen von Informationssystemen, Datenbank (DB)- und Information Retrieval (IR)-Systeme, bezüglich ihrer Erweiterung zu Wissensbasierten Systemen zu diskutieren. Eine solche Diskussion kann unter sehr verschiedenen Blickwinkeln erfolgen, hier beschränkt auf den Aspekt, jeweils mit Bezug zu PROLOG möglicher Erweiterungen von DB- und IR-Systemen zu untersuchen. Ein grundlegendes Verständnis von DB- und IR-Systemen wird vorausgesetzt. Die Arbeit beschränkt sich auf kurze Darstellungen wissensbasierter Systeme in Kap.1 und von PROLOG in Kap.2. Darauf aufbauend wird in Kap.3 die Erweiterung von DB- und in Kap.4 die Erweiterung von IR-Systemen jeweils zu Wissensbasierten Systemen behandelt

    Abstract
    Discusses the basic criteria for comparison of classification for libraries. Identifies a set of intellectual criteria, derived from the general theory of library classification as expounded by Dewey, Bliss, and Ranganathan. Compares LC, DC, and BC in relation criteria namely - order, university, hospitality, adaptability, terminology, relationship, synthesis, notational features - simplicity, brevity, expressiveness, specifity, synonymity, flexibility, correlation, case of use, revision and practical use. Highlights the value of comparative studies among classification schemes
