    Abstract
    Der Ausgangspunkt dieser Arbeit ist die Suchproblematik im World Wide Web. Suchmaschinen sind einerseits unverzichtbar für erfolgreiches Information Retrieval, andererseits wird ihnen eine mäßige Leistungsfähigkeit vorgeworfen. Das Thema dieser Arbeit ist die Untersuchung der Retrievaleffektivität deutschsprachiger Suchmaschinen. Es soll festgestellt werden, welche Retrievaleffektivität Nutzer derzeit erwarten können. Ein Ansatz, um die Retrievaleffektivität von Suchmaschinen zu erhöhen besteht darin, redaktionell von Menschen erstellte und automatisch generierte Suchergebnisse in einer Trefferliste zu vermengen. Ziel dieser Arbeit ist es, die Retrievaleffektivität solcher hybrider Systeme im Vergleich zu rein roboterbasierten Suchmaschinen zu evaluieren. Zunächst werden hierzu die grundlegenden Problembereiche bei der Evaluation von Retrievalsystemen analysiert. In Anlehnung an die von Tague-Sutcliff vorgeschlagene Methodik wird unter Beachtung der webspezifischen Besonderheiten eine mögliche Vorgehensweise erschlossen. Darauf aufbauend wird das konkrete Setting für die Durchführung der Evaluation erarbeitet und ein Retrievaleffektivitätstest bei den Suchmaschinen Lycos.de, AItaVista.de und QualiGo durchgeführt.

    Abstract
    Der Beitrag behandelt informationswissenschaftliche Perspektiven des Social Web. Hierzu wird zunächst anhand technologischer und sozialer Entwicklungstendenzen des Internets eine begriffliche Annäherung vorgenommen und die sich daraus ergebenden Phänomene mittels einer exemplarischen Darstellung wichtiger Dienste und Anwendungen veranschaulicht. Darauf aufsetzend wird das Social Web aus gesellschaftlicher Perspektive als eine globale Architektur der Partizipation eingeordnet, die in langfristiger Sicht das Potential für strukturelle Umbrüche in vielfältigen Bereichen und Handlungsfeldern in sich birgt. Dabei lassen sich aus informationswissenschaftlicher Perspektive insbesondere Auswirkungen auf die Ausprägung individueller und kollektiver Informations-, Wissens- und Kommunikationsprozesse als für die Disziplin relevante Aspekte begreifen. So bereichert das Social Web zentrale Themenfelder wie das Information Retrieval, die Mensch-Maschine-Interaktion oder das Wissensmanagement um neuartige Facetten. Zugleich werden neue Forschungsfelder virulent. Der Artikel skizziert beispielhaft einige dieser Aspekte, die derzeit in Hildesheim, insbesondere mit der neu geschaffenen Juniorprofessur "Social Networks and Collaborative Media", zu einer Erweiterung des informationswissenschaftlichen Lehr- und Forschungsportfolios führen. Ziel des Beitrags ist es zu verdeutlichen, dass die derzeitigen Entwicklungstendenzen des Internets die Bedeutung der Informationswissenschaft als wichtige zukunftsorientierte Lehr- und Forschungsdisziplin unterstreichen und zugleich Chancen und Bedarf für eine offensive Profilierung der Disziplin schaffen.

    Abstract
    K3, work in progress, is an acronym for Kollaboration (collaboration), Kommunikation (communication), and Kompetenz (competence). K3 provides a platform in the context of knowledge management to support collaborative knowledge production in learning environments. The underlying hypothesis states that collaborative discourse conciliates information as well as communication competence in learning contexts. The collaborative, communicative paradigm of K3 is implemented by asynchronous communication tools as a means of constructivist learning methodology. In this paper we will describe a K3 course. The lecture was organized and carried out at two places in two different countries (Germany and Switzerland) with students from different universities in the context of Library and Information Science. The paper informs about the management of the lecture and about the problems we had to run the lecture at two places. The circumstances in coordinating the presentations, the exercises, the examinations and evaluation, and the time schedule are presented. The conclusions of the lecturers and the results of a questionnaire for the students are explained in detail.
    Content
    K3 helps organizing a course with constructivist and instructional elements. It is used to run complex discussions and group work as presenting knowledge in a controlled environment. Besides basic functionalities like acting as a file server to exchange teaching materials and providing asynchronous communication, K3 offers: 1. A sophisticated system of intellectual, semi-automatic and automatic performance parameters as a means of permanent feedback and transparent gratification. 2. A MyK3 version to personalize the system for each user, be it a student or a lecturer. 3. Extended retrieval facilities. 4. A report generator to assemble a single student's or a group's contributions. 5. An elaborated administrator sub-system to enable the lecturers to organize their courses. 6. A visualization component, K3VIS to get a graphical, semistructured overview about a discourse. 7. A role system (moderator, presenter, researcher, and summarizer) to classify the responsibilities of students during a group work. 8. Typed discourse objects to organize and structure a discourse and allow ease of proximate actions, like retrieval and navigation.

    Abstract
    Die Konzeption von ENFORUM beruht auf einer verteilten Organisation der informationswissenschaftlichen Kompetenzzentren im deutschsprachigen Bereich und der kooperativen Erarbeitung von ENFORUM-Einträgen über elektronische Kommunikationsforen. ENFORUM wird zum einen in den wissenschaftlichen Kontext elektronischer Wörterbücher und Enzyklopädien eingeordnet, zum anderen werden Vor- und Nachteile asynchroner elektronischer Kommunikation diskutiert, mit dem Ergebnis, dass die Kompensationsleistung von Moderatoren in Kommunikationsforen für den Erfolg der Diskurse unabdingbar ist. Der aktuelle Stand von ENFORUM (März 2002) wird vorgestellt. ENFORUM ist ein voll operatives System mit adaptiver Benutzerverwaltung, flexiblen Such- und Navigationsformen und ersten Funktionen in Richtung Wissensplattform. Überlegungen zur funktionalen Weiterentwicklung von ENFORUM und zum Einsatz in der Ausbildung schließen den Artikel ab.

    Abstract
    Purpose - The purpose of this paper is to get a first approximation of the usefulness of online forums with regard to information seeking and knowledge generation. Design/methodology/approach - This study captures the characteristics of knowledge generation by examining the pragmatics and types of information needs of posted questions and by investigating knowledge related characteristics of discussion posts as well as the success of communication. Three online forums were examined. The data set consists of 55 threads, containing 533 posts which were categorized manually by two researchers. Findings - Results show that questioners often ask for personal estimations. Information needs often aim for actionable insights or uncertainty reduction. With regard to answers, factual information is the dominant content type and has the highest knowledge value as it is the strongest predictor with regard to the generation of new knowledge. Opinions are also relevant, but in a rather subsequent and complementary way. Emotional aspects are scarcely observed. Overall, results indicate that knowledge creation predominantly follows a socio-cultural paradigm of knowledge exchange. Research limitations/implications - Although the investigation captures important aspects of knowledge building processes, the measurement of the forums' knowledge value is still rather limited. Success is only partly measurable with the current scheme. The central coding category "new topical knowledge" is only of nominal value and therefore not able to compare different kinds of knowledge gains in the course of discussion. Originality/value - The investigation reaches out beyond studies that do not consider that the role and relevance of posts is dependent on the state of the discussion. Furthermore, the paper integrates two perspectives of knowledge value: the success of the questioner with regard to the expressed information need and the knowledge building value for communicants and readers.

    Abstract
    Die Online-Tagung im Rahmen des transnationalen Projektkurses "Intercultural perspectives on information literacy" wurde von Professor Dr. Joachim Griesbaum (Stiftung Universität Hildesheim, Institut für Informationswissenschaft), Dr. Tessy Thadathil (Symbiosis College of Arts and Commerce Pune, Indien), Sophie März (Stiftung Universität Hildesheim, Institut für Informationswissenschaft), Dr. Jini M. Jacob (Symbiosis College of Arts and Commerce Pune, Indien) und Theresia Woltermann (Stiftung Universität Hildesheim, Institut für Informationswissenschaft) organisiert. Der Einladung nach Hildesheim folgten rund 150 internationale Teilnehmende, unter anderem aus Indien, den USA, Niederlande, Südafrika, Bosnien und Herzegowina und Deutschland. Ziel der Tagung war es, die Ergebnisse des Projektkurses vorzustellen und einen Diskursraum für eine interkulturellen Perspektive der Informationskompetenz zu schaffen. Die zahlreichen Beiträge der teilnehmenden Studierenden und Angehörigen unterschiedlicher Fachrichtungen führten zu einem regen Diskurs.
