    Abstract
    Es wird ein relationales konzeptuelles Datenschema für ein Information Retrieval System (IRS) entworfen. Möglichkeiten für die interne Darstellung der Verweisrelation, welche die Beziehung zwischen Deskriptoren und Dokumenten herstellt, werden an den Beispielen der Datenbanksysteme SUPRA und ORACLE aufgezeigt. Für die Grundtypen der Standard-Retrievalsprache 'Common Command Language (CCL)' werden Transformationen in eine einfache relationale Datenmanipulationssprache angegeben. Die möglichen Alternativen, ein IRS an ein DBMS anzubinden, werden besprochen. Der letzte Teil des Beitrags befaßt sich mit Problemen der Integritätssicherung bei parallel zum Retrievalbetrieb laufendem Produktions- und Änderungsbetrieb

    Abstract
    Edited version of a report to the Australian Library and Information Association on the Conference on classification theory in the computer age, Albany, New York, 18-19 Nov 88, and on the meeting of the Dewey Editorial Policy Committee which preceded it. The focus of the Editorial Policy Committee Meeting lay in the following areas: browsing; potential for improved subject access; system design; potential conflict between shelf location and information retrieval; and users. At the Conference on classification theory in the computer age the following papers were presented: Applications of artificial intelligence to bibliographic classification, by Irene Travis; Automation and classification, By Elaine Svenonious; Subject classification and language processing for retrieval in large data bases, by Diana Scott; Implications for information processing, by Carol Mandel; and implications for information science education, by Richard Halsey.

    Abstract
    The development of the general theory of subject indexing language and of POPSI for organisation, storage and retrieval of subjects embodies in documents has a striking parallel in the search for and development of 'universal forms' and 'deep structure' in language and linguistic studies. This paper briefly traces the development of POPSI language as a metalanguage for information organisation and for generating information retrieval thesaurus. Also a computer-based system for generating an information retrieval thesaurus from modulated subject headings formulated according to POPSI which are enriched with certain codes for relating the terms in the subject headings is described. It is also mentioned that, if it is possible to form a table of equivalent terms in another language for the terms already used to generate the thesaurus, then it is possible to translate the thesaurus automatically into the other language
