    Abstract
    Ontologien werden eingesetzt, um durch semantische Fundierung insbesondere für das Dokumentenretrieval eine grundlegend bessere Basis zu haben, als dies gegenwärtiger Stand der Technik ist. Vorgestellt wird eine an der FH Darmstadt entwickelte und eingesetzte Ontologie, die den Gegenstandsbereich Hochschule sowohl breit abdecken und gleichzeitig differenziert semantisch beschreiben soll. Das Problem der semantischen Suche besteht nun darin, dass sie für Informationssuchende so einfach wie bei gängigen Suchmaschinen zu nutzen sein soll, und gleichzeitig auf der Grundlage des aufwendigen Informationsmodells hochwertige Ergebnisse liefern muss. Es wird beschrieben, welche Möglichkeiten die verwendete Software K-Infinity bereitstellt und mit welchem Konzept diese Möglichkeiten für eine semantische Suche nach Dokumenten und anderen Informationseinheiten (Personen, Veranstaltungen, Projekte etc.) eingesetzt werden.

    Content
    "Die kontinuierliche Optimierung der Informationsversorgung ist ein von allen Seiten unterstütztes Ziel in Forschung und Lehre. Neben der Verfügbarkeit an Literatur ist das Organisieren derselben, aber auch das Suchen, Finden und Erhalten von Informationen angesprochen. Die Anstrengungen der vergangenen Jahre für eine verbesserte Literaturrecherche haben in der Bibliothekswelt bereits zu einigen Erfolgen geführt. Inzwischen ist es selbstverständlich geworden, über das Internet in deutschen und internationalen Online-Katalogen nach relevanter Literatur zu suchen. Weiterführende Dienste wie Dokumentenlieferung oder direkte Verlinkung zu elektronischen Volltexten sind dabei nahtlos eingebunden. Die Weiterentwicklung bibliothekarischer Dienstleistungen werden ohne Unterbrechung vorangetrieben, zumal freie Suchmaschinen wie Google im "Information Retrieval", insbesondere durch Google-Scholar und Google-Buchsuche, einen beträchtlichen Konkurrenzdruck auf die Bibliotheken ausüben. Dabei drängt sich insgesamt der Eindruck auf, dass die Bibliotheken gegenüber den freien Suchmaschinen deren Entwicklungen hinterherlaufen. Ohne es als solches wahrzunehmen, verfügen die Bibliotheken im deutschsprachigen Raum jedoch über ein Instrument, mit dem sie im Wettbewerb mit Google um die Nutzerinnen wieder ihre Vorzüge herausstellen können. Es existiert längst ein Konzept, mit dessen Hilfe die Literaturrecherche inhaltlich-intuitiv gestaltet und damit ein Vorteil der Bibliotheksrecherche gegenüber kommerziellen Suchmaschinen herausgearbeitet werden kann. Das Konzept heißt "Regeln für den Schlagwortkatalog" (RSWK)' und bietet im Zusammenhang mit dem mittlerweile nicht mehr ganz so neuen Navigationskonzept "Faceted Browsing" ungeahnte Möglichkeiten eines intuitiven Recherschewerkzeuges, das Literatur gezielt inhaltlich entdecken lässt.

    Abstract
    The digital library system Daffodil is targeted at strategic support of users during the information search process. For searching, exploring and managing digital library objects it provides user-customisable information seeking patterns over a federation of heterogeneous digital libraries. In this paper evaluation results with respect to retrieval effectiveness, efficiency and user satisfaction are presented. The analysis focuses on strategic support for the scientific work-flow. Daffodil supports the whole work-flow, from data source selection over information seeking to the representation, organisation and reuse of information. By embedding high level search functionality into the scientific work-flow, the user experiences better strategic system support due to a more systematic work process. These ideas have been implemented in Daffodil followed by a qualitative evaluation. The evaluation has been conducted with 28 participants, ranging from information seeking novices to experts. The results are promising, as they support the chosen model.
