New OCR evaluation method prioritizes entity preservation over character accuracy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for evaluating Optical Character Recognition (OCR) systems, focusing on the preservation of entities like names and dates rather than just character accuracy. Using a benchmark from the Berrutti Archive with annotated entities, they compared various OCR systems, including general-purpose vision-language models. Their findings indicate that traditional metrics like Character Error Rate (CER) do not fully capture OCR quality, as some systems with lower exact-match scores still recover entities well with minor error tolerances, while others struggle significantly.

IMPACT This research could lead to more accurate historical document digitization by improving OCR evaluation standards.
