Abstract
Die Retrievalforschung in der Bibliothekswissenschaft hat in den letzten Jahrzehnten beachtliche Fortschritte gemacht. Automatische Indexierungsmethoden werden immer häufiger angewendet, obwohl dieses Thema in der Bibliothekswelt kontrovers diskutiert wird. Die Ergebnisse maschineller Erschließungsarbeit werden anhand von Retrievaltests festgehalten. Der Gegenstand dieser Arbeit ist die Darstellung von Retrievalexperimenten mit bibliothekarischen Daten. Zu Beginn werden die Grundlagen solcher Retrievaltests sowie das Cranfield-Paradigma erläutert. Es folgt eine Vorstellung verschiedener wissen schaftlicher Projekte aus diesem Forschungsfeld in chronologischer Reihenfolge. Wenn Verbindungen oder Einflussnahmen zwischen den einzelnen Projekten bestehen, werden diese herausgestellt. Im besonderen Umfang wird das Retrievalprojekt GELIC der TH Köln beschrieben, an dem der Autor dieser Arbeit beteiligt war. Obwohl es isolierte Retrievalprojekte gibt, lässt sich aus methodischer Sicht eine Verbindung von den frühesten Experimenten zu den heutigen Retrievalexperimenten herstellen. Diese Entwicklung ist noch nicht abgeschlossen.
