## Dataset Description

- **Repository:** [GitHub](https://github.com/Madjakul/HALvesting/tree/main)


## Dataset Summary

### overview:

This dataset is comprised of fulltext from open papers found on [Hyper Articles en Ligne (HAL)](https://hal.science/). Our dump is mostly english/french but gather papers written in 34 languages across 13 domains.

You can download the dataset using Hugging Face datasets:
```py
from datasets import load_dataset

ds = load_dataset("Madjakul/HALvest", "en")
```


### Details

Building the dataset is a four steps process: data fetching from HAL, data merging, data enriching and data filtering.

1. We first request [HAL's API](https://api.archives-ouvertes.fr/docs) in order to gather open research papers and parse it -- effectively sorting papers by language. Then, we download the PDFs of the fetched data.
2. Using [GROBID](https://github.com/kermitt2/grobid), we convert each PDF to an `xml-tei` format in order to have structured data. We convert each `xml-tei` file to a `txt` format before concatenating it with the paper's.
3. We compute some statistics about each document.
4. We filter the data based of off simple ratios to expurge badly encoded documents.

## Considerations for Using the Data

The corpus is extracted from the [HAL's open archive](https://hal.science/) which distributes scientific publications following open access principles. The corpus is made up of both creative commons licensed and copyrighted documents (distribution authorized on HAL by the publisher). This must be considered prior to using this dataset for any purpose, other than training deep learning models, data mining etc. We do not own any of the text from which these data has been extracted.
