Title
Digitalisierung historischer Zeitungen aus dem Blickwinkel der automatisierten Text- und Strukturerkennung (OCR)

Abstract
Die OCR Erkennung ist eine Schlüsseltechnologie, an der man bei der systematischen Digitalisierung von historischen Zeitungen nicht vorbeikommen wird. Obwohl vielfach nur eine Wortgenauigkeit von 80% oder weniger für Zeitungen des 19. und 20. Jahrhunderts zu erzielen sein wird, bietet dieser fehlerhafte Volltext trotzdem die Grundlage für eine ganze Reihe interessanter Anwendungen - von der Volltextsuche, über die Indexierung durch Suchmaschinen bis zur Online-Korrektur durch Benutzer. Der Einsatz der OCR erfordert allerdings sowohl bei der Projektplanung, der Gestaltung des Workflows, der Durchführung der Qualitätskontrolle als auch der Konzeption der Langzeitarchivierung und der Präsentation im Internet ein Umdenken gegenüber herkömmlichen Digitalisierungsprojekten.
