    Abstract
    Natürlicherweise sollte man erwarten, daß linguistische Textanalyseverfahren die Effektivität und Benutzerfreundlichkeit von Information Retrieval Systemen verbessern, da sowohl Dokumente als auch Suchanfragen die interessierenden Inhalte linguistisch enkodieren. Ein Retrievalabgleich auf der Ebene der linguistischen Inhaltsdarstellung müßte demzufolge zu besseren Retrievalsystemen führen als ein Abgleich auf Wort- oder gar Zeichenebene. Tatsächlich aber ist immer noch weitgehend unklar, inwieweit linguistische Textanalyseverfahren Retrievalsysteme verbessern können. Evaluationen von Retrievalsystemen mit linguistischen Komponenten führen nach wie vor zu unterschiedlichen, teils gegenläufigen Ergebnissen, obwohl die dazu erforderliche Computerlinguistik große Fortschritte gemacht hat. Wir gehen der Frage nach, wie es zu diesen kontraintuitiven Ergenissen kommt. Dazu wird der Stand der Kunst im linguistischen IR zusammengefaßt, so daß die Ergebnisse anhand des Vergleich verschiedener Evaluierungen diskutiert werden können.

    Abstract
    REALIST (Retrieval Aids by Linguistics and Statistics) is a tool which supplies the user of free text information retrieval systems with information about the terms in the databases. The resulting tables of terms show term relations according to their meaning in the database and form a kind of 'road map' of the database to give the user orientation help
