Steigerung der Erkennungsgenauigkeit durch maschinellen Abgleich verschiedener durch OCR erzeugter Volltexte

Abstract
Die Erzeugung von Volltexten durch OCR-Programme und die dabeieingesetzten Verfahren werden zusammen mit den dabei auftretenden Fehlern vorgestellt. Dabei wird nach systemunabhängigen und systemimmanenten Fehlern und den Bewertungskriterien zur Beurteilung der Programme unterschieden. Basierend auf der Hypothese, die durch Beispiele gestützt wird, daß systemimmanente Fehler durch den Abgleich von Volltexten, die mit verschiedenen OCR-Programmen erzeugt wurden, reduziert werden können, werden eine Versuchsanordnung und das Ergebnis daraus vorgestellt. Kernpunkt des Abgleichs ist ein Wortvergleichsalgorithmus, der einen vollautomatischen Vergleich zuläßt und damit den manuellen Nachbearbeitungsaufwand reduziert
