|
## Dataset Details |
|
|
|
Handwritten Text Recognition (HTR) has emerged as a crucial tool for converting manuscripts images into machine-readable formats, |
|
enabling researchers and scholars to analyse vast collections efficiently. |
|
Despite significant technological progress, establishing consistent ground truth across projects for HTR tasks, |
|
particularly for complex and heterogeneous historical sources like medieval manuscripts in Latin scripts (8th-15th century CE), remains nonetheless challenging. |
|
We introduce the **Consistent Approaches to Transcribing Manuscripts (CATMuS)** dataset for medieval manuscripts, |
|
which offers: |
|
1. a uniform framework for annotation practices for medieval manuscripts, |
|
2. a benchmarking environment for evaluating automatic text recognition models across multiple dimensions thanks to rich metadata (century of production, |
|
language, genre, script, etc.), |
|
3. a benchmarking environment for other tasks (such as script classification or dating approaches), |
|
4. a benchmarking environment and finally for exploratory work pertaining to computer vision and digital paleography around line-based tasks, such as generative approaches. |
|
|
|
Developed through collaboration among various institutions and projects, CATMuS provides an inter-compatible dataset spanning more than 200 manuscripts and incunabula in 10 |
|
different languages, comprising over 160,000 lines of text and 5 million characters spanning from the 8th century to the 16th. |
|
|
|
The dataset's consistency in transcription approaches aims to mitigate challenges arising from the diversity in standards for medieval manuscript transcriptions, |
|
providing a comprehensive benchmark for evaluating HTR models on historical sources. |

## Uses |
|
|
|
### Direct Use |
|
|
|
- Handwritten Text Recognition |
|
- Date classification |
|
- Script classification |
|
|
|
### Out-of-Scope Use |
|

|
## Dataset Structure |
|
|
|
- Data contains the main `split` that is loaded through `load_dataset("CATMuS/medieval")` |
|
- Data can be split with each manuscript inside train, val and test using the `gen_split` columns which results in a 90/5/5 split |
|
- The image is in the `im` column, and the text in the `text` column |

## Bias, Risks, and Limitations |
|
|
|
The data are skewed toward Old French, Middle Dutch and Spanish, specifically from the 14th century. |
|
|
|
The only language that is represented over all centuries is Latin, and in each scripts. The other language with a coverage close to Latin is Old French. |
|
|
|
Only one document is available in Old English. |

## Glossary |
|
|
|
|
|
 |
|
|
|
- Scripts: In the middle ages, the writing style changed over time, specifically in "litterary" manuscripts, for which we call the general scripts "Bookscripts". This is what CATMuS Medieval covers at the time |
