Title

PADOK-II : Untersuchungen zur Volltextproblematik und zur interpretativen Analyse der Retrievalprotokolle

Source

Nachrichten für Dokumentation. 41(1990) H.1, S.21-26

Year

Abstract

Dieser Beitrag baut auf dem Bericht über das methodische Konzept, über die Durchführung und die Ergebnisse der PADOK-II-Retrievaltests auf (Krause/Wormser-Hacker). Hier werden die Ergebnisse von Zusatztests zum Einfluß des Umfangs der zugrundeliegenden Dokumente (Volltext vs. Titel+Abstract) beschrieben, die eine deutliche Beeinträchtigung der Recall-Werte bei reduziertem Dokumentenumfang zeigen. Zur interpretativen Analyse der Retrievalprotokolle werden vor allem die methodische Einbindung, Ansatzpunkte der Analyse und erste Ergebnisse vorgestelt.
