Danish books (Fraktur)

Twenty complete pages: ten from Søren Kierkegaard’s Af en endnu Levendes Papirer (1838) and ten from Hans Christian Andersen’s Billedbog uden Billeder (1840). The Royal Danish Library digitised both books; Wikimedia Commons supplies the unaltered scans.

All 20 pages form the complete Danish Fraktur task in the Danish and Scandinavian benchmarks. The additional comparison was performed by an AI assistant, not an independent human transcription team. The five initial models were selected by Swedish Fraktur CER; Swedish inputs are cropped lines, while this task evaluates whole pages.

The model reads an entire page and returns its text in reading order. 20 images.

Norwegian handwriting (NorHand)

NorHand contains Norwegian letters and diaries from the 19th and early 20th centuries. The line images capture historical handwriting and spelling; the source release resizes each image to a height of 128 pixels.

The model reads an image cropped to one line of text. 1,000 images.
