PastReader 2025

This is the dataset used in the PastReader 2025 shared task at IberLEF 2025. This dataset has been generated from the historical press publications in the public domain, digitized by the National Library of Spain (BNE) and available for free access through Hemeroteca Digital. The BNE has undertaken efforts to improve these resulting texts through various approaches. One of the most significant initiatives involves open and collaborative OCR correction (among other types of projects) through the ComunidadBNE platform: https://comunidad.bne.es/.
