    Abstract
    In dieser Arbeit werden der Entwurf und die Entwicklung eines Vermittlersystems erläutert, das vor allem hochspezialisierte Wissenschaftler und Ingenieure bei der eigenständigen Suche in einer Vielzahl wichtiger Online-Datenbanken unterstützt. Online-Recherchen sind bisher überwiegend den Informationsvermittlern vorbehalten, die die Verbindung herstellen zwischen dem Informationssuchenden und dem Online-Dienst, der die Information möglicherweise anbietet. Üblicherweise schlägt der Informationssuchende Suchbegriffe vor und beurteilt die Relevanz der Ergebnisse, während die Aufgabe des Informationsvermittlers darin besteht, passende Datenbanken und Hosts auszuwählen und dann die Suche durchzuführen, wobei er auf sein Wissen über Strukturen und Inhalte der verschiedenen Datenbanken sowie über Online-Suchtechniken zurückgreift. Teile dieses komplexen Wissens sind in unser System integriert worden und stehen den Selten- bzw. Endnutzern in höchst benutzerfreundlicher Form zur Verfügung. Zukünftige Weiterentwicklungen des Systems werden auch professionelle Online-Rechercheure umfassend unterstützen

    Abstract
    Ausgehend von einer Diskussion der Gestaltungskonzeptionen und der Leistungsfähigkeit heutiger Volltext-Retrieval-Systeme wird ein Überblick über den Leistungsumfang des für die Aufbereitung und Präsentation von Textinformation zuständigen Systems TWRM-TOPOGRAPHIC gegeben. TWRM-TOPOGRAPHIC ist Teil eines neuartigen Informationssystems, das sich auf inhaltsorientierte Repräsentation von Volltexten stützt. Die beiden wesentlichsten Leistungsmerkmale von TWRM-TOPOGRAPHIC sind die graphische Retrievaldialogführung und die flexible, situationsgerechte Aufbereitung und Präsentation von Textwissen: Die Dialogführung erlaubt dem Benutzer die direkte Navigation in den auf dem Bildschirm graphisch dargestellten Wissensstrukturen, die Selektion dargestellter Objekte zur Formulierung einer Query sowie das Wechseln des Abstraktionsniveaus der dargestellten Textinformation. Die Aufbereitung und die Präsentation von Textwissen sind kognitiv-ergonomisch begründet und berücksichtigen sowohl die begrenzte Aufnahmekapazität der Benutzer als auch die Bedeutung der zeitlichen Anordnung von Informationseinheiten für die Wahmehmungs- und Gedächtnisleistung der Rezipienten. Textwissen wird in unterschiedlichen Abstraktionsstufen präsentiert: von einer sehr generischen Ebene über Wissensgraphen, automatisch generierten Abstracts bis zur diskursiven Form der Textpassage. Die Generierungskomponente des Systems leistet einen Beitrag zum situationsgerechten Systemverhalten dadurch, daß sie aus semantischen Text-Repräsentationsstrukturen unter Berücksichtigung textueller Wohlgeformtheitsbedingungen benutzerangepaßte Abstracts mit unterschiedlichem Themenschwerpunkt und variabler Ausführlichkeit produziert. Die Erprobung verschiedener LayoutVerfahren im Projekt TWRM-TOPOGRAPHIC wird durch ein flexibles, objektorientiert spezifiziertes User-Interface-Mangagement-System (UIMS) unterstützt, dessen Objektklassen und deren Interaktionsmöglichkeiten vorgestellt werden. Die Darstellung des Systems wird mit einem ausführlichen Dialogbeispiel abgeschlossen, das die Funktion des Interface und die Wirkung der drei zentralen Operatoren (Select, Zoom und Browse) im Retrievaldialog illustriert.

    Abstract
    Storing and accessing texts in a conceptual format has a number of advantages over traditional document retrieval methods. A conceptual format facilitates natural language access to text information. It can support imprecise and inexact queries, conceptual information summarisation, and, ultimately, document translation. Describes 2 methods which have been implemented in a prototype intelligent information retrieval system calles SCISOR (System for Conceptual Information Summarisation, Organization and Retrieval). Describes the text processing, language acquisition, and summarisation components of SCISOR

    Abstract
    AUTOCAT soll ein in der Routineproduktion gebrauchstüchtiges wissensbasiertes System zur Formalerfassung von Zeitschriftenaufsätzen nach INIS-Regeln werden. Der AUTOCAT-Prototyp übernimmt eine Zeitschrift vom optischen Leser und liefert Output in der Form eines ausgefüllten INIS-Datenblattes ab. Die Formalerfassung untergliedert sich in die schwierigere Erkennung von Informationselementen und deren leichtere Transformation nach INIS-Regeln. AUTOCAT erkennt die Informationselemente mit seiner Repräsentation des Erwartungswissens über Zeitschriftenstrukturen. Sie wurde anhand von rund 330 Kernzeitschriften des Faches Physik validiert. Ihr Schwerpunkt ist die Darstellung der Zusammensetzungsstruktur des komplexen Informationsobjetkt Zeitschrift. Konkrete Zeitschriften werden abgeleitet, indem man die Beschreibungen der Zeitschriftenkomponenten mit Typangaben spezifiziert. Die Repräsentation ist in PROLOG implementiert

    Abstract
    Ausgehend von einer Diskussion der Gestaltungskonzeptionen und der Leistungsfähigkeit heutiger Volltext-Retrieval-Systeme wird ein Überblick über den Leistungsumfang des für die Aufbereitung und Präsentation von Textinformation zuständigen Systems TWRM-TOPOGRAPHIC gegeben. TWRM-TOPOGRAPHIC ist Teil eines neuartigen Informationssystems, das sich auf inhaltsorientierte Repräsentation von Volltexten stützt. Die beiden wesentlichsten Leistungsmerkmale von TWRM-TOPOGRAPHIC sind die graphische Retrievaldialogführung und die flexible, situationsgerechte Aufbereitung und Präsentation von Textwissen: Die Dialogführung erlaubt dem Benutzer die direkte Navigation in den auf dem Bildschirm graphisch dargestellten Wissensstrukturen, die Selektion dargestellter Objekte zur Formulierung einer Query sowie das Wechseln des Abstraktionsniveaus der dargestellten Textinformation. Die Aufbereitung und die Präsentation von Textwissen sind kognitiv-ergonomisch begründet und berücksichtigen sowohl die begrenzte Aufnahmekapazität der Benutzer als auch die Bedeutung der zeitlichen Anordnung von Informationseinheiten für die Wahmehmungs- und Gedächtnisleistung der Rezipienten. Textwissen wird in unterschiedlichen Abstraktionsstufen präsentiert: von einer sehr generischen Ebene über Wissensgraphen, automatisch generierten Abstracts bis zur diskursiven Form der Textpassage. Die Generierungskomponente des Systems leistet einen Beitrag zum situationsgerechten Systemverhalten dadurch, daß sie aus semantischen Text-Repräsentationsstrukturen unter Berücksichtigung textueller Wohlgeformtheitsbedingungen benutzerangepaßte Abstracts mit unterschiedlichem Themenschwerpunkt und variabler Ausführlichkeit produziert. Die Erprobung verschiedener LayoutVerfahren im Projekt TWRM-TOPOGRAPHIC wird durch ein flexibles, objektorientiert spezifiziertes User-Interface-Mangagement-System (UIMS) unterstützt, dessen Objektklassen und deren Interaktionsmöglichkeiten vorgestellt werden. Die Darstellung des Systems wird mit einem ausführlichen Dialogbeispiel abgeschlossen, das die Funktion des Interface und die Wirkung der drei zentralen Operatoren (Select, Zoom und Browse) im Retrievaldialog illustriert.

    Abstract
    Computer have been used in 2 areas of printed index production: to sort entries and fromat printed indexes, and to derive a series of index entries from a minimum intellectual input. Computer indexing enables more indexing terms to be used as well as weighted terms, links and roles. Interest in automatic indexing peaked in the mid-1960s and has since declined. Interest in machine-aided indexing concentrates on using the computer for on-line display or for indexing by extraction. Computers have also made possible the implementation of retrieval systems without indexing-free text systems. Considers future prospects and needs

    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
    Examines the accepted principles of controlled indexing, in published abstracting/indexing services and databases from the unusual aspect of the publisher's need to minimize production costs. Detailed information concerning the producution of LISA is presented showing income and costs. Ways in which factors involved in controlled indexing may be seen to manifest themselves in production parameters are shown by plotting graphs of the numbers of abstracts and index pages against numbers of abstracts for 77 individual issues of LISA. The close fit of the data to straight lines, with correlation coefficients approaching unity, provides a means of managing the size of individual issues to yield minimum printing/binding costs. The extended use of the CRG classification notation to provide automatic extraction of chain indexing strings and associated cross-references is described in detail. The gains in staff productivity resulting from this and other procedures are indicated with reference to the expansion in LISA's coverage between 1978 and 1984.
