Abstract
In Zusammenarbeit mit der norwegischen Suchtechnologie-Firma Fast Search & Transfer hat die Universitätsbibliothek Bielefeld den Prototyp einer Suchmaschine für wissenschaftliche Bibliotheken entwickelt. Dieser demonstriert jetzt mit dem öffentlichen Zugriff auf ausgewählte digitalisierte Sammlungen der Projektteilnehmer die neuen Möglichkeiten des akademischen Retrieval. <http://www.heise.de/RealMedia/ads/adstream_lx.ads/www.heise.de/newsticker/meldungen/wissenschaft/954604605/Middle1/he-test-contentads/zaehler.html/38363566383735383364653062323630?_RM_EMPTY_> Während kommerzielle Suchmaschinen wie Google oder Yahoo sich nicht an akademischen Kriterien orientieren, beschränkt sich die Bielefeld Academic Search Engine (BASE ) auf die von wissenschaftlichen Bibliotheken erschlossenen und aufbereiteten Inhalte. Dazu gehören Hochschulschriften, Preprints, elektronische Zeitschriften und digitale Sammlungen, wie beispielsweise die "Internet Library of Early Journals" des Oxford University Library Service und die "Wissenschaftlichen Rezensionsorgane und Literaturzeitschriften des 18. und 19. Jahrhunderts aus dem deutschen Sprachraum" der UB Bielefeld. Wer etwa bei Google die Stichworte "Immanuel Kant" +Frieden eingibt, kommt zwar schnell an den Originaltext des Aufsatzes "Zum ewigen Frieden" heran, tut sich jedoch schwer, unter den bunt gemischten über 11.000 Treffern gezielt weiter zu recherchieren. Das BASE-Modell dagegen stellt dem Nutzer hierfür vielfältige Navigationshilfen und Metainformationen zur Verfügung. So erleichtert unter anderem die Verfeinerung der Suche auf das Erscheinungsjahr den Zugriff auf die zeitgenössische Diskussion der berühmten Schrift des Königsberger Philosophen. Derzeit ermöglicht der BASE-Prototyp das Retrieval in 15 verschiedenen Archivquellen. Darunter befinden sich die Zeitschriften der Aufklärung, die Elektronischen Dissertationen der Universität Bochum, das elektronische Journal Documenta Mathematica sowie die Mathematischen Volltexte des Springer-Verlags. Der geplante Ausbau soll sich auf eine verteilte Architektur stützen, in der von einzelnen Bibliotheken lokal erstellte Indexe gemeinsam zu einem virtuellen Master-Index beitragen. Dies würde dem Nutzer die nahtlose Navigation durch die verteilten Bestände erlauben."
