| # 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. | |
