Title
Verbesserung der OCR in digitalen Sammlungen von Bibliotheken

Abstract
Möglichkeiten zur Verbesserung der automatischen Texterkennung (OCR) in digitalen Sammlungen insbesondere durch computerlinguistische Methoden werden beschrieben und bisherige PostOCR-Verfahren analysiert. Im Gegensatz zu diesen Möglichkeiten aus der Forschung oder aus einzelnen Projekten unterscheidet sich die momentane Anwendung von OCR in der Bibliothekspraxis wesentlich und nutzt das Potential nur teilweise aus.
