<!-- Provide a quick summary of the dataset. -->
ZelaiHandi🌱: A Large Open Dataset of Basque. 
ZelaiHandi (large pasture in Basque) is the largest open corpus publicly available in Basque (as of 2024/02/27), containing roughly 560M tokens. 
The corpus is composed of clean texts extracted from specific web sources, including exclusively content with free licenses.    

The dataset will receive yearly updates.

The corpus is released with the aim of "feeding" LLMs like llama-2, Latxa, etc. Of course other non "herbivore" models can also use ZelaiHandi.

## Bias, Risks, and Limitations

<!-- This section is meant to convey both technical and sociotechnical limitations. -->
This corpus inherits the Basque society's stereotypes and biases. Moreover, it might include explicit language, slurs and hate speech, (mostly on the fictional text from literature and subtitles).

<!--### Recommendations -->

<!-- This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->

<!--Users should be made aware of the risks, biases and limitations of the dataset. 
We suggest filtering sources as literature and subtitles that might contain hate speech, slurs or explicit language before pretraining an LLM for end tasks like interactive chat.-->

## Citation

Coming soon.
<!--We plan to release a paper soon, but, for now, please, cite as follows:

**BibTeX:**
```bibtex
@misc{ZelaiHaundi,
 title     = "{Zelai-Haundi: A Big Open Dataset to Feed the next Gen of Basque LLMs}",
