STEM Wikipedia Subset
This dataset was created by filtering the wikimedia/wikipedia dump to retain only science-related articles.
Filtering Process
- A handpicked list of ~80 STEM keywords was defined.
- Each Wikipedia article's
textfield was scanned for these keywords. - A count of keyword matches was computed for each article.
- Only articles with ≥ X keyword hits were retained.
- Only the
textandsourcecolumns were preserved.
Use Case
This dataset is suitable for pretraining or domain adaptation of language models focused on STEM reasoning or QA tasks.
