STEM Wikipedia Subset

This dataset was created by filtering the wikimedia/wikipedia dump to retain only science-related articles.

Filtering Process

1. A handpicked list of ~80 STEM keywords was defined.
2. Each Wikipedia article's text field was scanned for these keywords.
3. A count of keyword matches was computed for each article.
4. Only articles with ≥ X keyword hits were retained.
5. Only the text and source columns were preserved.

Use Case

This dataset is suitable for pretraining or domain adaptation of language models focused on STEM reasoning or QA tasks.
