Abstract
Die Forschung zur Evaluierung von Information Retrieval Systemen hat in den letzten Jahren neue Richtungen eingeschlagen und interessante Ergebnisse erzielt. Während früher primär die Überlegenheit einzelner Verfahren in heterogenen Anwendungsszenarien im Fokus stand, gerät zunehmend die Validität der Evaluierungsmethodik ins Zentrum der Aufmerksamkeit. Dieser Artikel fasst die aktuelle Forschung zu innovativen Evaluierungsmaßen und zur Zuverlässigkeit des so genannten Cranfield-Paradigmas zusammen.
