    Abstract
    Im Rahmen von MILOS II wurde das erste MILOS-Projekt zur automatischen Indexierung von Titeldaten um eine semantischer Komponente erweitert, indem Thesaurusrelationen der Schlagwortnormdatei eingebunden wurden. Der abschließend zur Evaluierung durchgeführte Retrievaltest und seine Ergebnisse stehen im Mittelpunkt dieses Texts. Zusätzlich wird ein Überblick über bereits durchgeführte Retrievaltests (vorwiegend des anglo-amerikanischen Raums) gegeben und es wird erläutert, welche grundlegenden Fragestellungen bei der praktischen Durchführung eines Retrievaltests zu beachten sind
