- Abstract
- Nur wenige Dokumentationsmethoden werden mit dem Namen ihrer Entwickler assoziiert. Ausnahmen sind Melvil Dewey (DDC), S.R. Ranganathan (Colon Classification) - und Norbert Henrichs. Seine Textwortmethode ermöglicht die Indexierung und das Retrieval von Literatur aus Fachgebieten, die keine allseits akzeptierte Fachterminologie vorweisen, also viele Sozial- und Geisteswissenschaften, vorneweg die Philosophie. Für den Einsatz in der elektronischen Philosophie-Dokumentation hat Henrichs in den späten sechziger Jahren die Textwortmethode entworfen. Er ist damit nicht nur einer der Pioniere der Anwendung der elektronischen Datenverarbeitung in der Informationspraxis, sondern auch der Pionier bei der Dokumentation terminologisch nicht starrer Fachsprachen

- Abstract
- Informationsdienste werden heutzutage von großen Teilen der Bevölkerung im Berufs- wie im Privatleben genutzt. Es ist ein wichtiges informationswissenschaftliches Thema, Informationsdienste adäquat zu beschreiben und ihre Qualität zu bewerten. Unser Information Service Evaluation (ISE) Modell führt unterschiedliche Traditionen der Evaluations- sowie der Technologieakzeptanzforschung zusammen und besteht aus fünf Dimensionen: Qualität des Informationsdienstes, Nutzer, Informationsakzeptanz, Informationsumfeld und Zeit. Der Überblicksartikel erläutert diese Dimension und bietet einen Einblick in ein flexibel handhabbares und umfassendes holistisches Modell der Beschreibung und Bewertung von Informationsdiensten.

- Abstract
- Informationelle Städte sind prototypische Städte der Wissensgesellschaft. Als informationelle Weltstädte sind sie neue Zentren der Macht. In ihnen dominieren gemäß Manuel Castells - neben den Spaces of Place - die Spaces of Flow (Kapital-, Macht- und Informationsflüsse). Zentral sind die IKT-Infrastruktur und die kognitive Infrastruktur (Basis der Wissensstadt und der kreativen Stadt) sowie das Wissensmanagement auf Stadtebene. Digitale Bibliotheken sorgen für den Zugriff auf das explizite Weltwissen. Zur Stimulierung lokaler impliziter Informationsflüsse schafft die informationelle Stadt kreative Cluster und Orte persönlicher Kontakte. In informationellen Städten herrschen Einkommens- und Berufspolarisierung zugunsten gut ausgebildeter Arbeitskräfte. Finanzdienstleister, wissensintensive High-tech-Industriefirmen, Firmen der Informationswirtschaft sowie weitere kreative wie wissensintensive Dienstleister bestimmen die Unternehmensstruktur solcher Städte. Attraktive Einrichtungen für Kultur, Freizeitgestaltung und Konsum bilden weiche Standortfaktoren. Wesentlich für den Aufbau einer informationellen Stadt sind der politische Wille und das Setzen regulierender Maßstäbe (E-Governance). Der Artikel arbeitet Indikatoren heraus, mittels derer der Grad der "Informationalität" einer Stadt bestimmbar wird und versucht auf Basis der Prinzipien der Netzökonomie eine Hypothese aufzustellen, warum bestimmte Städte den Übergang zu informationellen Städten bewältigen und andere (die in relative Bedeutungslosigkeit versinken) nicht.

- Abstract
- Suchmaschinen im World Wide Web wird nachgesagt, dass sie - insbesondere im Vergleich zur Retrievalsoftware kommerzieller Online-Archive suboptimale Methoden und Werkzeuge einsetzen. Elaborierte befehlsorientierte Retrievalsysteme sind vom Laien gar nicht und vom Professional nur dann zu bedienen, wenn man stets damit arbeitet. Die Suchsysteme einiger "independents", also isolierter Informationsproduzenten im Internet, zeichnen sich durch einen Minimalismus aus, der an den Befehlsumfang anfangs der 70er Jahre erinnert. Retrievalsoftware in Intranets, wenn sie denn überhaupt benutzt wird, setzt fast ausnahmslos auf automatische Methoden von Indexierung und Retrieval und ignoriert dabei nahezu vollständig dokumentarisches Know how. Suchmaschinen bzw. Retrievalsysteme - wir wollen beide Bezeichnungen synonym verwenden - bereiten demnach, egal wo sie vorkommen, Schwierigkeiten. An ihrer Qualität wird gezweifelt. Aber was heißt überhaupt: Qualität von Suchmaschinen? Was zeichnet ein gutes Retrievalsystem aus? Und was fehlt einem schlechten? Wir wollen eine Liste von Kriterien entwickeln, die für gutes Suchen (und Finden!) wesentlich sind. Es geht also ausschließlich um Quantität und Qualität der Suchoptionen, nicht um weitere Leistungsindikatoren wie Geschwindigkeit oder ergonomische Benutzerschnittstellen. Stillschweigend vorausgesetzt wirdjedoch der Abschied von ausschließlich befehlsorientierten Systemen, d.h. wir unterstellen Bildschirmgestaltungen, die die Befehle intuitiv einleuchtend darstellen. Unsere Checkliste enthält nur solche Optionen, die entweder (bei irgendwelchen Systemen) schon im Einsatz sind (und wiederholt damit zum Teil Altbekanntes) oder deren technische Realisierungsmöglichkeit bereits in experimentellen Umgebungen aufgezeigt worden ist. insofern ist die Liste eine Minimalforderung an Retrievalsysteme, die durchaus erweiterungsfähig ist. Gegliedert wird der Kriterienkatalog nach (1.) den Basisfunktionen zur Suche singulärer Datensätze, (2.) den informetrischen Funktionen zur Charakterisierunggewisser Nachweismengen sowie (3.) den Kriterien zur Mächtigkeit automatischer Indexierung und natürlichsprachiger Suche

- Abstract
- Ovid Technologies speist sich aus unterschiedlichen Unternehmensgeschichten; die Erfahrungen von BRS, SilverPlatter, Ovid und Wolters-Kluwer ergänzen sich in den derzeit betriebenen zwei Plattformen Ovid und SilverPlatter. Ovid spricht vor allem praktizierende wie forschende Spezialisten in der medizinisch-biowissenschaftlichen Sparte an, während SilverPlatter eher auf den gesamten akademischen Betrieb abzielt. Wir konzentrieren uns in diesem Artikel auf die Ovid-Plattform und vernachlässigen SilverPlatter. Das Interessante an Ovid ist die Einheit von bibliographischen Nachweisdaten, Volltexten und praxisrelevanten klinischen Entscheidungshilfen. U.E. lohnt die Retrievaloberfläche von Ovid und die hier praktizierte durchgehende Verlinkung von Nachweisen und Volltexten und von Volltexten untereinander einer näheren Betrachtung. Unsere Ergebnisse stützen sich auf den Fragebogen, Gespräche mit Jens Gräßler, National Sales Manager Germany, vom deutschen Ovid-Büro in Berlin sowie auf Tests im März und im April 2004.

- Abstract
- Die Informationswissenschaft im Sinne des Düsseldorfer Forschungsprogramms untersucht das Auswerten, Bereitstellen, Suchen und Finden von relevantem (vorwiegend digital vorliegendem) Wissen. Sie umfasst ein Spektrum von fünf Teildisziplinen. Eine zentrale Rolle spielt das Information Retrieval, die Wissenschaft der Suchmaschinen unter Berücksichtigung technischer Systeme und Informationsbedürfnisse der Nutzer. Wissensrepräsentation thematisiert Metadaten sowie Methoden und Werkzeuge für den Einsatz beim Indexieren und Referieren. Anwendungsnahe Teilgebiete sind das Wissensmanagement mit der Konzentration auf das (Ver-)Teilen unternehmensinternen Wissens und der Integration externen Wissens in die betriebliche Informationswirtschaft sowie Forschungen zum Informationsmarkt mit einem weiten Gegenstandsbereich, der sich von der Informationsinfrastruktur eines Landes über die Branche elektronischer Informationsdienste und dem Informationsrecht bis hin zur Netzökonomie erstreckt. Informationswissenschaft geht - soweit möglich - empirisch vor und erfasst ihre Gegenstände mittels quantitativer Methoden. Informetrische Forschungen umfassen die deskriptive Informetrie, die Webometrie, die Szientometrie genauso wie die Evaluation von Informationssystemen und Nutzer- sowie Informationsbedarfsanalysen. Die Informationswissenschaft der Heinrich-Heine-Universität Düsseldorf verfolgt ein Forschungsprogramm, das sich allen Teildisziplinen widmet. Unser Begriff von "Forschungsprogramm" folgt den wissenschaftstheoretischen Überlegungen von Imre Lakatos.

- Abstract
- Was hat Information mit Mobilität zu tun? Nun, zunächst kann Information Mobilität unterstützen, Fahrerinformationssysteme sind ein bekanntes Beispiel. Information kann darüber hinaus unnötige Mobilität vermeiden helfen, indem die Information mobil wird und seinen Empfänger ortsungebunden findet. Die ' "ubiquitäre" Information erreicht den Außendienstmitarbeiter fern vom Back Office, den Studenten fern von der Hochschule oder einen Kollegen in seinem Home Office fern vom Standort der Firma. Information kann auch zu mehr Mobilität führen, denken wir nur an Lieferungen im Anschluss an Bestellungen im E-Commerce. (Dieser Aspekt wird allerdings in Regensburg nicht angesprochen). Letztendlich muss auch die "geistige Mobilität" beim Lehren und Lernen mit den neuen digitalen Medien genannt werden, eine Mobilität, die sich eher im Hintergrund abspielt, die aber einer 'stillen Revolution" gleichkommt. Das Generalthema "Information und Mobilität" des achten Internationalen Symposiums für Informationswissenschaft (ISI) wurde nicht zufällig beim diesjährigen Tagungsort in Regensburg gewählt, denn an der Universität Regensburg existiert seit Jahren ein interdisziplinäres Forschungszentrum für Information und Mobilität. Außerhalb des Generalthemas bringt das ISI - wie gewohnt - ein zusätzliches Spektrum informationswissenschaftlicher Themen und - auch wie gewohnt - mit dem "Best Student Paper Award" den Wettbewerb um die beste studentische Leistung der letzten zwei Jahre - diesmal mit einem Sieger und mit einem Sonderpreis. Fahrerinformationssysteme: akustische und/oder visuelle Metainformationen?

- Abstract
- Norbert Henrichs war ein bedeutender Pionier der Informationswissenschaft in Deutschland. Wir widmen uns der von ihm aufgebauten Philosophiedokumentation und der damit eng verbundenen Textwortmethode sowie einer frühen Form der informetrischen Themenanalyse. Herausgestellt wird seine führende Rolle beim Bemühen um eine Institutionalisierung der Informationswissenschaft, die allerdings mit der nachhaltigen Etablierung der Gesellschaft für Information und Dokumentation (GID) nicht gelang. In seinem Spätwerk hinterfragte Henrichs den kapitalistischen Informationsmarkt und stellt das "Menschsein im Informationszeitalter" in den Fokus seiner Betrachtungen.

- Abstract
- Themenentdeckung und -verfolgung (topic detection and tracking; TDT) fasst unterschiedliche Dokumente zu einem Thema zusammen und bietet dem Nutzer zunächst das Thema und erst in einem zweiten Schritt die einzelnen Dokumente zur Anzeige an. TDT ist nützlich bei Nachrichten sowie bei Blog-Einträgen. Ein bekanntes Beispiel ist Google News. Der Artikel bespricht den Forschungsstand zu TDT und diskutiert den Einsatz von TDT bei News-Informationsdiensten wie z.B. Factiva oder LexisNexis. Dort ist TDT zweifach wichtig: Erstens ist es (analog zu Google News) bei Profildiensten einsetzbar, zweitens ist es möglich, Dokumente zum gleichen Thema in einen Ordner zu klassieren, um bei einer retrospektiven Recherche die Treffermenge geordnet nach unterschiedlichen Themen anzubieten (und dies ohne Nutzung einer Dokumentationssprache).

- Abstract
- Deutschsprachige Fachzeitschriften des Bibliotheks- und Informationswesens (BID) werden über Kennwerte zur Leserwahrnehmung (Lesehäufigkeit, Anwendbarkeit der gelesenen Inhalte, Publikationshäufigkeit, Publikationspräferenz), Zitatenanalyse (Impact Factor, Halbwertszeit der Referenzen, Referenzen pro Artikel, Anteil der Zeitschriftenselbstreferenzen) und der Redaktion (Struktur der Autoren- und Leserschaft, Artikelauswahl, Ablehnungsquote, Überarbeitungsquote) szientometrisch beschrieben. Besonderes Augenmerk wird auf die Gegenüberstellung der Ergebnisse der Teilstudien gelegt. Die deutschsprachigen BID-Zeitschriften werden von Praktikern als Autoren wie als Leser dominiert. Praktiker schreiben für Praktiker, es wird wenig zitiert, aktuelle Themen überwiegen. Die Ablehnungsquoten eingereichter Artikel sind gering; durchgehendes Peer Review ist bei der Artikelauswahl die Ausnahme. Einige deutschsprachige BID-Zeitschriften (vor allem die Verbandszeitschriften) gleichen informationellen Inseln. Eine informations- und bibliothekswissenschaftliche Zeitschrift, die internationalen Qualitätsstandards folgt und die für das gesamte BID relevante Themen behandelt, fehlt in den deutschsprachigen Ländern völlig.

- Abstract
- Es wird versucht, quantitative Werte zur Messung der Informationskompetenz von Volkswirtschaften zu entwickeln. Zudem sollen Korrelationen zwischen der Informationskompetenz und der wirtschaftlichen Leistungsfähigkeit darüber Auskunft geben, wie Gesamtwirtschaft und Inforinationswirtschaft eines Landes zusammenhängen. Operationalisierung. "Informationskompetenz" wird durch den Umsatz auf nationalen Business-toBusiness-Märkten operationalisiert. Abgeleitete Größen sind Pro-KopfImport- und Exportvolumen, Informationsproduktion und -konsumtion (insgesamt und pro Kopf) sowie der Anteil der Informationswirtschaft am jeweiligen nationalen Bruttoinlandsprodukt (BIP). Datenbasis. Im Rahmen der "Member States' Study" der Europäischen Kommission wurden für den gesamten Europäischen Wirtschaftsraum (EWR; Staaten der Europäischen Union sowie Norwegen und Island) für die Jahre 1994 und 1997 Umsatzzahlen der 17 Länder erhoben. Diese Zahlen wurden auf Plausibilität überprüft und unserer Fragestellung zugrundegelegt. Ergebnisse. Der Anteil der Informationswirtschaft am BIP ist derart gering (EWR: 0,070% im Jahr 1997), daß er nahezu ignoriert werden kann. Die Korrelation zwischen dem BIP pro Kopf und der Informationskonsumtion pro Kopf ist jedoch äußerst hoch (+0,715 im Jahr 1994 und +0,642 im Jahr 1997), ebenso die Korrelation zwischen BIP pro Kopf und Informationsimport pro Kopf (+0,588 im Jahr 1994 sowie +0,583 im Jahr 1997)

- 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?
