    Abstract
    In Anlehnung an die in den neunziger Jahren durchgeführten Erschließungsprojekte MILOS I und MILOS II, die die Eignung eines Verfahrens zur automatischen Indexierung für Bibliothekskataloge zum Thema hatten, wurde eine empirische Untersuchung anhand einer repräsentativen Stichprobe von Titelsätzen aus dem Österreichischen Verbundkatalog durchgeführt. Ziel war die Prüfung und Bewertung der Einsatzmöglichkeit dieses Verfahrens in den Online-Katalogen des Verbundes. Der Realsituation der OPAC-Benutzung gemäß wurde ausschließlich die Auswirkung auf den automatisch generierten Begriffen angereicherten Basic Index ("Alle Felder") untersucht. Dazu wurden 100 Suchanfragen zunächst im ursprünglichen Basic Index und sodann im angereicherten Basic Index in einem OPAC unter Aleph 500 durchgeführt. Die Tests erbrachten einen Zuwachs an relevanten Treffern bei nur leichten Verlusten an Precision, eine Reduktion der Nulltreffer-Ergebnisse sowie Aufschlüsse über die Auswirkung einer vorhandenen verbalen Sacherschließung.

    Abstract
    Prof. Dr. Harald Zimmermann, Universität des Saarlandes, berichtete über zukunftsfähige Erschließungsverfahren, die intellektuelle Leistungen einsparen helfen und trotzdem den Weg zur gewünschten Literatur öffnen können sollen. Er erinnerte an das von Lustig und Knorz in den 80er Jahren entwickelte Verfahren Air/Phys. Dort lernt das System mit dem Anwachsen eines lexikalischen Inventars (ISBN 3-487-07825-2).
