Intended Use
- Greek web-text pretraining experiments
- HPLT-only baselines
- Mixture construction with curated GlossAPI sources
- Tokenizer and cleaning analysis over a large filtered web corpus
Notes
- This dataset is intentionally HPLT-only; the broader mixed corpus lives at
fffoivos/glossapi-greek-nanochat-pretraining-dataset. - Source licensing remains governed by the upstream HPLT release.
