Title
Was wir über OPAC-Nutzer wissen : fehlertolerante Suchprozesse in OPACs

Abstract
Rekapituliert aus Ergebnissen der OOPAC-Nutzerforschung werden einige wesentliche Schwierigkeiten, die Endnutzer bei der Literaturrecherche in OPACs haben, und erklärt werden einige softwareseitige Maßnahmen zur fehlertoleranten OPAC-Gestaltung. Schwierigkeiten bei der OPAC-Nutzung sind: keine Treffer (kein recall), zu viele Treffer (Ballast), Orientierungslosigkeit, unverständliche Optionen, ungenügende Daten für Relevanzbeurteilung, Überschätzung des Datenbankinhaltes, unwirksame Hilfestellung. Einige in deutschen OPACs noch nicht implementierte Maßnahmen mit fehlertoleranter Auswirkung sind: automatische Wortformenreduktion, automatische Rechtschreibkorrektur, relevance ranking, Relevanzrückmeldung und Recherche mit Koindexaten
