Abstract

Sowohl die rechnergestützte Informationssuche in einer realen Bibliothek als auch die in einer digitalen Bibliothek stellen heute immer noch ein zeitaufwändiges und damit teures Unterfangen dar. Als wesentliche Gründe können drei Problembereiche identifiziert werden. Zum Ersten existieren zahlreiche Zugangspunkte mit jeweils unterschiedlichen Formularen, Anfragesprachen und unterschiedlicher inhaltlicher Qualität. Zum Zweiten fehlt eine dringend benötigte anbieterübergreifende Integration der Informationen und Dienste. Zum Dritten schließlich wird der Benutzer durch die unbefriedigende Funktionalität nicht ausreichend in seinem Informationssuchprozess unterstützt. Alle diese Punkte führen letztendlich zu langwierigen und damit teuren Suchprozessen. Diese Dissertation stellt sich der Aufgabe, den oben genannten Problembereichen in geeigneter Weise zu begegnen und eine adäquate Lösung zu erarbeiten. Dazu erhält der Benutzer durch strategische Unterstützung in Form von verschiedenen integrierten Diensten von einem aktiven System eine Hilfestellung, um so sein Informationsbedürfnis effektiv und effizient befriedigen zu können. Die Ergebnisse dieser Arbeit, die durch eine ausführliche Evaluation belegt worden sind, bieten sowohl theoretische als auch praktische Lösungen zur Entwicklung und zur Nutzung von digitalen Bibliotheken: - Der theoretische Teil zeigt ein Modell für verteilte Bibliotheksdienste auf, strukturiert diese und stellt sie in einen Gesamtzusammenhang. Dadurch wird die Modellierung neuer Dienste erleichtert und ein positiver Nutzen kann schon im Vorfeld diskutiert werden. - Der praktische Teil basiert auf dem entwickelten Modell und ermöglicht - den Benutzern, effektiv und effizient einer umfassenden Literatursuche nachzugehen und diese auch nachhaltig zu verwalten. - den Entwicklern von digitalen Bibliotheken durch Zugriff auf eine Vielzahl von Basisdiensten dar¨uber hinausgehende Dienste zu entwickeln. Insgesamt kann das Daffodil-System als Basisarchitektur für die Entwicklung und Evaluation von digitalen Bibliotheken verwendet werden und trägt somit zur wissenschaftlichen Forschung in diesem Bereich bei.
