This repository contains 3 datasets created within the POPP project ([Project for the Oceration of the Paris Population Census](https://popp.hypotheses.org/#ancre2)) for the task of handwriting text recognition. These datasets have been published in [Recognition and information extraction in historical handwritten tables: toward understanding early 20th century Paris census at DAS 2022](https://link.springer.com/chapter/10.1007/978-3-031-06555-2_10).

The 3 datasets are called “Generic dataset”, “Belleville”, and “Chaussée d’Antin” and contains lines made from the extracted rows of census tables from 1926. Each table in the Paris census contains 30 rows, thus each page in these datasets corresponds to 30 lines.

We publish here only the lines. If you want the pages, go [here](https://zenodo.org/record/6581158). This dataset is made 4800 annotated lines extracted from 80 double pages of the 1926 Paris census.

## Data Info

Since the lines are extracted from table rows, we defined 4 special characters to describe the structure of the text:
- ¤ : indicates an empty cell
- / : indicates the separation into columns
- ? : indicates that the content of the cell following this symbol is written above the regular baseline
- ! : indicates that the content of the cell following this symbol is written below the regular baseline

There are three splits: train, valid and test.

## How to use it

```python
from datasets import load_dataset
import numpy as np

dataset = load_dataset("agomberto/FrenchCensus-handwritten-texts")
i = np.random.randint(len(dataset['train']))
img = dataset['train']['image'][i]
text = dataset['train']['text'][i]
print(text)
img

abstract="We aim to build a vast database (up to 9 million individuals) from the handwritten tabular nominal census of Paris of 1926, 1931 and 1936, each composed of about 100,000 handwritten simple pages in a tabular format. We created a complete pipeline that goes from the scan of double pages to text prediction while minimizing the need for segmentation labels. We describe how weighted finite state transducers, writer specialization and self-training further improved our results. We also introduce through this communication two annotated datasets for handwriting recognition that are now publicly available, and an open-source toolkit to apply WFST on CTC lattices.",
