    Abstract
    Seit einigen Jahren hat sich in Europa eine Initiative zur Bewertung von Information Retrieval in mehrsprachigen Kontexten etabliert. Das Cross Language Evaluation forum (CLEF) wird von der EU gefördert und kooperiert mit Evaluierungsprojekten in den USA (TREC) und in Japan (NTCIR). Dieser Artikel stellt das CLEF in den Rahmen der anderen internationalen Initiativen. Neue Entwicklungen sowohl bei den Information Retrieval Systemen als auch bei den Evaluierungsmethoden werden aufgezeit. Die hohe Anzahl von Teilnehmern aus Forschungsinstitutionen und der Industrie beweist die steigende Bedeutung des sprachübergreifenden Retrievals

    Abstract
    Information Retrieval hat sich zu einer Schlüsseltechnologie in der Wissensgesellschaft entwickelt. Die Anzahl der täglichen Anfragen an Internet-Suchmaschinen bildet nur einen Indikator für die große Bedeutung dieses Themas. Der Sammelbandband informiert über Themen wie Information Retrieval-Grundlagen, Retrieval Systeme, Digitale Bibliotheken, Evaluierung und Multilinguale Systeme, beschreibt Anwendungsszenarien und setzt sich mit neuen Herausforderungen an das Information Retrieval auseinander. Die Beiträge behandeln aktuelle Themen und neue Herausforderungen an das Information Retrieval. Die intensive Beteiligung der Informationswissenschaft der Universität Hildesheim am Cross Language Evaluation Forum (CLEF), einer europäischen Evaluierungsinitiative zur Erforschung mehrsprachiger Retrieval Systeme, berührt mehrere der Beiträge. Ebenso spielen Anwendungsszenarien und die Auseinandersetzung mit aktuellen und praktischen Fragestellungen eine große Rolle.
