    Abstract
    Der Beitrag enthält eine Darstellung zur Durchführung und zu den Ergebnissen des Retrievaltests zum AIR/PHYS-Projekt. Er zählt mit seinen 309 Fragen und 15.000 Dokumenten zu den größten Retrievaltests, die bisher zur Evaluierung automatisierter Indexierungs- oder Retrievalverfahren vorgenommen wurden.
