    Abstract
    Report on research carried out in Brazil for a doctoral thesis, investigating the possibility of using the PRECIS indexing system for documents in Portuguese. Discusses the theoretical basis of PRECIS, and presents the resultss of a study in comparing the use PRECIS to index 2 samples of documents, in English and Portuguese respectively. Concludes that, with minor modifications to take account of the differences in structure between the 2 languages. PRECIS could produce satisfactory results for documents in Portuguese. This suggests the further possibility that PRECIS - because of its sound logical basis rather than its complex linguistic theory - could become a multilingual indexing system.

    Abstract
    CONDOR ist ein Modell eines modularen, integrierten DB-/IR-Systems, mit dem sowohl strukturierte als auch unstrukturierte Daten (Textdaten) verarbeiet werden können. Die abzuspeichernden Informationen werden weitgehend automatich erschlossen. Da ein breiter Benutzerkreis Zugang zum System haben soll, sind verschiedene Dialogformen (Kommando, natürlichsprachlich, Formular, Menü) implementiert. Es wird versucht, sie in einer systematischen Oberflächengestaltung des Systems zusammenzuführen, um eine möglichst einfache Bedienung für den einzelnen Benutzer bei hoher Nutzungsflexibilität des Systems zu erreichen

    Abstract
    Bennenung und Begriff von 'Wissen' spielen im Bereich der Klassifikation eine wesentliche Rolle, da Klassifikationssysteme und Thesauri als Wissensordnungen verstanden werden können, deren Komponenten Wissenseinheiten (Begriffe) sind und diese wiederum aus Wissenselementen (Merkmalen) bestehen. In der Terminologie des Gebiets der Künstlichen Intelligenz tauchen nunmehr ebenfalls Komposita mit 'Wissen' auf. Es wird versucht, den augenfälligen Berührungspunkten dieser beiden Tätigkeitsbereiche nachzugehen und die Folgerungen aus dem 'know-how' beider Richtungen im Sinne einer möglichen gegenseitigen Hilfestellung aufzuzeigen

    Abstract
    Auf dem Hintergrund der aktuellen OPAC-Entwicklung in Deutschland werden im ersten Teil einzelne Aspekte des OPAC-Designs kommentiert. Es wird u.a. auch auf Möglichkeiten einer Standardisierung der Schnittstelle Retrieval-Software / Benutzeroberfläche eingegangen. Die derzeit dominierenden Online-Kataloge sind für eine Massenbenutzung nur bedingt geeignet, da sie in hohem Maße fehlerintolerant sind, eine Analyse nach Suchfeldern verlangen und mit grundsätzlichen Mängeln der Boole'schen Suchlogik behaftet sind. Im zweiten Teil werden werden Alternativen diskutiert, zum einen in Form eines alphabetisch sortierten Online-Katalogs, zum anderen in Form intelligenter bibliographischer Auskunftssysteme, die Ähnlichkeitssuchen bzw. sog. 'Closest-Match-Suchen' gestatten. Hierzu werden verschiedene Konzepte und Vorschläge vorgestellt

    Abstract
    CD-ROMs sind in mancher Hinsicht kleine Loch-Ness-Monster: man kann viele Artikel über sie lesen, sie werden oft abgebildet, sind aber selten in Aktion zu sehen. Der enorme Speicherplatz (bis zu 650 MB) der auf einer CD-ROM zur Verfügung steht,fasziniert sowohl Benutzer als auch Produzenten, es gibt aber viele Hindernisse, wenn man dieses neue Medium wirklich nutzen will. Die allzu kluge Marketingstrategie der verkäufer ist wahrscheinlich der größte Feind dieser optischen Platten. Auf der anderen Seite findet man mehr und mehr Beispiele guter Benutzeroberflächen, schneller Suchsysteme und sogar Hoffnungen auf einheitliche Standards für Treiberprogramme u. dgl. Die Hauptabteilung Information + Dokumentation der Henkel KGaA produzierte bereits 1986 eine Test-CD-ROM, die den Online-Katalog der Chemischen Bibliothek enthielt. Regelmäßig benutzt wird auch eine Reihe anderer CD-ROMs, einige wenige liegen noch in einem Dornröschenschlaf, bis auch die Endbenutzer selbst in der vorgesehenen Mediothek (als Teilstück der Chemischen Bibliothek) in ihnen recherchieren können. Da die meisten auf CD-ROM verfügbaren Daten auch online recherchierbar sind, werden Vor- und Nachteile der CD-ROMs diskutiert. Innerhalb einer Firma ist die Datenspeicherung auf einem Großrechner in vielen Fällen nach wie vor günstiger, wenn die Daten für firmeninterne Recherchen beschafft werden können

    Abstract
    Aus der Benutzung der Universitätsbibliothek Ulm wurde eine Halbwertszeit-Funktion in der naturwissenschaftlichen Literatur von t1/2=5 Jahren bestimmt. Eine interessante Abweichung von dieser Halbwertszeit-Funktion ist bei der Bestellung der neuesten Zeitschriften zu beobachten. Der Grund hierfür liegt vermutlich darin, daß Wissenschaftler das Vierfache an neuester Literatur lesen müssen, um wissenschaftliche Trends zu überschauen. Eine weitere Abweichung ist in der ältesten Literatur festzustellen, bei den sog. 'citation classics'. Übereinstimmung zeigt sich im Zitier- und Kopierverhalten bei Zeitschriftenliteratur, die älter als 2 Jahre ist. Etwa 27% der an die UB Ulm gerichteten Literaturanforderungen betreffen Zeitschriftenaufsätze mit einem Alter von über 10 Jahren, da diese Bestände für die Benutzer nur schwer zugänglich sind. Dies zeigt die große Bedeutung einer Freihand-Bibliothek

    Abstract
    A summary of brain theory is given so far as it is contained within the framework of Localization Theory. Difficulties of this "conventional theory" are traced back to a specific deficiency: there is no way to express relations between active cells (as for instance their representing parts of the same object). A new theory is proposed to cure this deficiency. It introduces a new kind of dynamical control, termed synaptic modulation, according to which synapses switch between a conducting and a non- conducting state. The dynamics of this variable is controlled on a fast time scale by correlations in the temporal fine structure of cellular signals. Furthermore, conventional synaptic plasticity is replaced by a refined version. Synaptic modulation and plasticity form the basis for short-term and long-term memory, respectively. Signal correlations, shaped by the variable network, express structure and relationships within objects. In particular, the figure-ground problem may be solved in this way. Synaptic modulation introduces exibility into cerebral networks which is necessary to solve the invariance problem. Since momentarily useless connections are deactivated, interference between di erent memory traces can be reduced, and memory capacity increased, in comparison with conventional associative memory

    Abstract
    Als 'klassifikatorische Ganzheiten' gelten hier Wissensgebiete, bzw. ihre Begriffe. Die Muster, die sich aufgrund der Begriffsrelationen von Wissensgebieten gewinnen lassen, werden sowohl durch formkategoriale als auch durch seinskategoriale Bezüge dieser Begriffe geprägt. Logische und linguistische Untersuchungen haben gezeigt, daß sich Wissensbereiche und Wissensgebiete formkategorial jeweils zu Triaden zusammenordnen lassen und als solche entsprechende Wissensmuster bilden. Ein universales System von 3**3 Triaden von Wissensgebieten wird vorgestellt und erläutert. Es wird dabei gezeigt, wie sich auch in der Interaktion von Wissensgebieten miteinander, z.B. in der Verwendung der Methoden und Verfahren eines Gebietes in einem anderen Gebiet oder der Fundierung eines Gebiets durch ein anderes gewisse Muster abzeichnen, die die Systemstellen eines solchen Systems apriori und auch aposteriori "systematisch" besetzen, ohne die innere Ordnung des Systems und seiner Triaden zu beeinträchtigen. Auf diese Weisen wird durch den Aspekt des internalen Bezugs von Wissensmustern (gegenüber dem o.g. elementalen und totalen) ein Musterwissen gewonnen, das insbesondere auch bei der Benutzung eines solchen Systems von großem Nutzen sein kann, da es das Gedächtnis stützt, die Mustererkennung ermöglicht und dementsprechend die Handhabung bei Einspeicherung und Retrieval von zu ordenbarem Wissen erleichtert.
