Dataset Card for ZelaiHandi🌱

ZelaiHandi🌱: A Large Open Dataset of Basque. ZelaiHandi, which means "large pasture" in Basque, is the largest collection of freely licensed and clean Basque texts to date (February 28th, 2024), gathered from selected web sources. This collection comprises approximately 560 million tokens.

The dataset will receive yearly updates.

The corpus has been released with the objective of “feeding” Large Language Models. Naturally, models that are not strictly "herbivorous" can also ingest ZelaiHandi.
