HTRomance, Medieval Spain corpus of ground-truth for Handwritten Text Recognition and Layout Segmentation

Introduction

This ground-truth dataset has been carefully built around the idea of having generic data for building a strong and reliable model for HTR of Latin manuscripts. Each manuscript should have around 10 columns (5 bi-columns pages or 10 pages of single column).

Data follow the Segmonto guidelines.

Note

The repository contains two XML files per image. The ones suffixed with .chocomufin.xml are normalized in order to be compliant with other datasets following the same guidelines. The others are more specific to this repository. We recommend using the normalized documents.

Credits

• Transcriptions: Julie Bordier.
• Supervision and manuscript selection: Matthias Gille Levenson & Olivier Brisville-Fertin.
• Project management: Thibault Clérice & Alix Chagué.

Transcription guidelines

The transcription guidelines are described in a paper available on HAL and published in the Journal for Open Humanities Data. The paper provides specific details about the selection process, the transcription methods and choices, as well as details about the output (mainly the Generic CREMMA Model for Medieval Manuscripts (Latin and Old French) for Kraken)

Data

ALTO and images can be found in the directory called data/. Each subfolder of data/ corresponds to a single manuscript, identified by its shelfmark.
