# STEM Wikipedia Subset

This dataset was created by filtering the [wikimedia/wikipedia](https://huggingface.co/datasets/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.
