    Abstract
    Reports results of a bibliometric study of the literature of Qigong: a relaxation technique used to teach patients to control their heart rate, blood pressure, temperature and other involuntary functions through controlles breathing. All articles indexed in the MEDLINE CD-ROM database, between 1965 and 1995 were identified using 'breathing exercises' MeSH term. The articles were analyzed for geographical and language distribution and a ranking exercise enabled a core list of periodicals to be identified. In addition, the study shed light on the changing frequency of the MeSH terms and evaluated the research areas by measuring the information from these respective MeSH headings

    Abstract
    Mittels Patentindikatoren ist es möglich, wesentliche Erfinder und Erfindungen hervorzuheben. Die Anwendbarkeit von Patentindikatoren ist zeitabhängig. Der eingeführte Patentindikator SPI (Science-on-Patent Influence) signalisiert den Grad der Wissenschaftlichkeit des Erfinders und seiner Erfindungen. Seine rarionelle Nutzung zur Ermittlung von Kerninformation wird vorgestellt

    Abstract
    Als Maß für die Produktivität und den Einfluß von Forschern, wissenschaftlichen Einrichtungen und Fachbereichen dienen häufig anhand von Publikations- und Zitationsanalysen erstellte Ranglisten. Doch nach welchen Kriterien sind die in elektronischen Fachdatenbanken gespeicherten Informationen auszuwerten, um ein einigermaßen zutreffendes Abbild der Forschungsleistung zu erhalten?

    Abstract
    Die Häufigkeit von Zitierungen wissenschaftlicher Publikationen kann in erster Näherung als Maßstab für ihre inhaltliche Qualität gelten. Die Journal Citation Reports (JCR) des ISI ordnen über die Auszählung von Referenzen aus mehreren tausend Fachzeitschriften durch diverse bibliometrische Indikatoren Zeitschriften einen bestimmten Wert zu. Der Aufbau der Datensammlung sowie die verwendeten Indikatoren werden näher beschrieben. 2 Methoden werden vorgestellt, mit denen in Anwendung der JCR eine Menge von Kernzeitschriften für ein Fachgebiet ermittelt werden kann. Probleme der Zuverlässigkeit bei der Sammlung und Verarbeitung der Zitierdaten durch die JCR werden dargestellt. Die Anwendbarkeit einer Zitatenanalyse für den Bestandsaufbau bei Fachzeitschriften wird untersucht. Sie kann zur Entscheidungsfindung beitragen, andere Methoden aber nicht ersetzen

    Abstract
    Ein überfordertes Gutachter-System, knapper fließende Forschungsgelder sowie die starke Faszination von Ranglisten bewirken zunehmend den Einsatz bibliometrischer Methoden zur Messung von Forschungsqualität. Grundlage der meisten Bewertungen ist der Science Citation Index, der nun auch in der Version als Online-Datenbank für umfangreiche Analysen genutzt werden kann. Erweiterungen der Retrievalsprache beim Host STN International ermöglichen statistische Analysen, die bisher nur dem SCI-Hersteller und wenigen Spezialisten vorbehalten waren. Voraussetzung für eine sinnvolle Anwendung sind vor allem die Wahl geeigneter Selektionskriterien sowie die sorgfältige Interpretation der Ergebnisse im Rahmen der Grenzen dieser Methoden

    Abstract
    Citation is a worldwide phenomenon. It needs to be considered in the international context. This study examines 4 common modalities (physical accessibility, cognitive accessibility, perceived quality, and perceived importance) underlying the complex citation practice by translation analysis. In an analysis of the Chinese literature in library and information science, it was found that there is a very strong correlation between languages cited and languages translated (r=0.978). The overall national citation pattern of foreign publications is highly correlated with its translation pattern (r=0.897). There is approximately 57% overlap between the group of the 60 most heavily cited authors and the group of the 60 most frequently translated authors. Highly cited publications are more likely to be translated (54.5 vs. 13.8%)

    Abstract
    Die Beiträge behandeln aus verschiedenen Blickwinkeln einen durch die Begriffe Sozialwissenschaft-Informatik-Information abgegrenzten, interdisziplinären Themenkomplex. Gerade in den Sozialwissenschaften haben die qualitative Textinterpretation und die Suche nach typischen, einzelnen Fällen ihren festen Stellenwert, und automatische Informationssuche und Informationsaufbereitung sind zu unverzichtbaren Forschungsinstrumenten geworden. Dieser Band enthält eine Vielzahl von Fachbeiträgen, die im Rahmen entsprechender Spezialveranstaltungen entstanden sind oder eigens für diesen Band geschrieben wurden. Sowohl als Einführungen wie auch im Rahmen spezieller Fragestellungen werden Ansätze aus den Gebieten Künstliche Intelligenz, Bilderkennung, Kommunikationsnetze, Hypertext, Szientometrie, Bibliometrie u.a., jeweils mit Bezug auf sozialwissenschaftliche Anwendung, vorgestellt

    Abstract
    Die Ermittlung von Kerninformationen mittels informetrischer Methoden erfordert die Nutzung formaler Bewertungskriterien wie Publikationshäufigkeit, Zitierhäufigkeit und Patentfamiliengröße. Es werden die Zeitabhängigkeit, die Austauschbarkeit und die Voraussetzungen für die Anwendung der formalen Bewertungskriterien erläutert.

    Abstract
    Literaturdatenbanken wurden eigentlich mit zwei Zielen aufgebaut: einerseits Fachliteratur zu archivieren und zu dokumentieren und andererseits die Literaturhinweise den Wissenschaftlern für Recherchen zur Verfügung zu stellen. Aus diesen gespeicherten Datenmengen kann man baer auch allgemeine Erkenntnisse über die Literatur eines Fachgebietes und das Verhalten der Forscher gewinnen. Vor allem seit den sechziger Jahren, seit dem Aufbau des Science Citation Index - in dem man auch nach zitierten Arbeiten suchen kann - gibt es eine Fülle von informationswisenschaftlichen und wissenssoziologischen Untersuchungen mit Datenbanken

    Abstract
    In einer früheren Studie wurde bereits der 'informationelle Mehrwert' von bibliographischen Datenbanken durch bibliometrische Nutzung untersucht. Im folgenden soll nun eine visuelle Oberfläche vorgestellt werden, die mit Hilfe einer bibliometrischen 'Sekundärdatenbank' einerseits die Nutzungsmöglichkeiten der zugrundeliegenden bibliographischen Datenbanken vor allem in den Bereichen Wissenschaftsinformation, Forschungsevaluation und Wissenschaftspolitik erweitern soll, andererseits aber auch eine Rückkopplung zu den Aufgaben des traditionellen Retrievals erlaubt. Die visuelle Oberfläche 'Visual Bibliometrics' ist eine Erweiterung des CD-Edition des 'Science Citation Index' und des 'Social Science Citation Index'

    Abstract
    There is a decrease in the incidence of explicit references to a paper over time, hence the assumption that information ages. In a study which attempts to discover whether information really ages it is necessary to include eponyms, anonyms and footnote references. Reports a pilot study which demonstrates that there is an increase over time in the frequency of use of eponyms

    Abstract
    Reports results of a bibliometric study of 111 theses accepted by the Department of Library and Information Science, Ahmadu Bello University, Zaria, Nigeria, between 1977 and 1992. The analysis was based on year, type and degree awarded, subject, type of library and geographical area. Concludes that the highest number of submissions was 1991, when 108 MLS theses (97,29%) and 3 PhD theses (2,71%) were accepted. Libraries and readers was the most concetrated subject while the academic library was the most discussed type of library

    Abstract
    Conducts a goodness of fit test for 2 models for Bradford's law given by Egghe and Smolkov. Concludes that Smolkov's model is of comparatively higher accuracy. Finally points out the necessity of carrying out statistical tests for comparisons more frequently for the new models of Bradford's law in the development of the law in order to get the best model

    Abstract
    International bibliographic databases and related biblimetric indicators together provide an analytical framework and appropriate measure to cover both the 'supply side' - research capabilities and outputs - and 'demand side' - collaboration, diffusion and citation impact - related to information and communication technologies (ICT) research. Presents results of such a bibliometric study describing macro level features of this ICT knowledge base
