  7. 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.
