Ground-truth of the Tarima project (HTR of Maghrebi Arabic documents). > **[May 22, 2026]**: The official version of our dataset is now also available at the line-level for download directly on Hugging Face! # TariMa dataset Ground-truth of the TariMa project (HTR/OCR of Maghrebi Arabic documents).

Historians using Arabic manuscripts had neglected the study of this genre, in comparison with religious sciences or linguistics. ## Dataset composition The RASAM dataset already provides a strong baseline for the recognition of Arabic Maghrebi scripts. This new dataset is focused on specific contents or vocabulary lacking in previous RASAM models. It contains 120 images, for a total of: * 144 TextRegions * 2.673 TextLines (2.364 transcribed) * 27.583 words (11.307 unique) * 146.667 characters The TariMa dataset comprises different image resolution and size (width from 982px to 8049px), different layouts (double page, multiple columns), state of conservation, and also m …
