    Abstract
    In der folgenden Studie wird eine Komponente für eine visuelle Benutzerschnittstelle zu Textdatenbanken entworfen. Mit Hilfe einer Terminologievisualisierung wird dem Benutzer eine Hilfestellung bei der Relevanzbewertung von Dokumenten und bei der Erweiterung seiner visuellen Anfrage an das Retrieval-System gegeben. Dazu werden zuerst die grundlegenden Information-Retrieval-Modelle eingehender vorgestellt, d.h., generelle Retrieval-Modelle, Retrievaloperationen und spezielle Retrieval-Modelle wie Text-Retrieval werden erläutert. Die Funktionalität eines Text-Retrieval-Systems wird vorgestellt. Darüber hinaus werden bereits existierende Implementierungen visueller Information-Retrieval-Benutzerschnittstellen vorgestellt. Im weiteren Verlauf der Arbeit werden mögliche Visualisierungen der mit Hilfe eines Text-Retrieval-Systems gefundenen Dokumente aufgezeigt. Es werden mehrere Vorschläge zur Visualisierung von Thesauri diskutiert. Es wird gezeigt, wie neuronale Netze zur Kartierung eines Eingabebereiches benutzt werden können. Klassifikationsebenen einer objekt-orientierten Annäherung eines Information-Retrieval-Systems werden vorgestellt. In diesem Zusammenhang werden auch die Eigenschaften von Thesauri sowie die Architektur und Funktion eines Parsersystems erläutert. Mit diesen Voraussetzung wird die Implementierung einer visuellen Terminologierunterstützung realisiert. Abschließend wird ein Fazit zur vorgestellten Realisierung basierend auf einem Drei-Schichten-Modell von [Agosti et al. 1990] gezogen.

    Abstract
    Ausgangslage Die Katalog-Recherchen über Internet, also von außerhalb der Bibliothek, nehmen erwartungsgemäß stark zu bzw. sind mittlerweile die Regel. Damit ist natürlich das Bedürfnis und die Notwendigkeit gewachsen, über den Titel hinaus zusätzliche inhaltliche Informationen zu erhalten, die es erlauben, die Zweckmäßigkeit wesentlich besser abschätzen zu können, eine Bestellung vorzunehmen oder vielleicht auch 50 km in die Bibliothek zu fahren, um ein Buch zu entleihen. Dieses Informationsdefizit wird zunehmend als gravierender Mangel erfahren. Inhaltsverzeichnisse referieren den Inhalt kurz und prägnant. Sie sind die erste Stelle, welche zur Relevanz-Beurteilung herangezogen wird. Fast alle relevanten Terme einer Fachbuchpublikation finden sich bereits dort. Andererseits wird immer deutlicher, dass die dem bibliothekarischen Paradigma entsprechende intellektuelle Indexierung der einzelnen dokumentarischen Einheiten mit den engsten umfassenden dokumentationssprachlichen Termen (Schlagwörter, Klassen) zwar eine notwendige, aber keinesfalls hinreichende Methode darstellt, das teuer erworbene Bibliotheksgut Information für den Benutzer in seiner spezifischen Problemstellung zu aktivieren und als Informationsdienstleistung anbieten zu können. Informationen zu sehr speziellen Fragestellungen, die oft nur in kürzeren Abschnitten (Kapitel) erörtert werden, sind derzeit nur indirekt, mit großem Zeitaufwand und oft überhaupt nicht auffindbar. Sie liegen sozusagen brach. Die Tiefe der intellektuellen Indexierung bis in einzelne inhaltliche Details zu erweitern, ist aus personellen und damit auch finanziellen Gesichtspunkten nicht vertretbar. Bibliotheken fallen deshalb in der Wahrnehmung von Informationssuchenden immer mehr zurück. Die enorme Informationsvielfalt liegt hinter dem Informations- bzw. Recherchehorizont der bibliographischen Aufnahmen im Katalog.

    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.
