+# ChemRxiv Paragraphs
+
+This dataset consists of paragraphs from ChemRxiv papers with **CC BY 4.0** and **CC BY-NC 4.0** licenses, sourced from the [BASF-AI/ChemRxiv-Papers](https://huggingface.co/datasets/BASF-AI/ChemRxiv-Papers) dataset. Paragraphs are extracted using Grobid, and filtered using an average log word probability method similar to the approach in [allenai/peS2o](https://huggingface.co/datasets/allenai/peS2o). Paragraphs with fewer than 50 words are excluded.
+
+The number of unique papers in each license category is as follows:
+
+- **CC BY 4.0:** 5,848 papers
+- **CC BY-NC 4.0:** 3,082 papers
+
+To obtain metadata for each paper, join on the `id` column with the [BASF-AI/ChemRxiv-Papers](https://huggingface.co/datasets/BASF-AI/ChemRxiv-Papers) dataset.
+
+To access paragraphs for a specific license, use the `name` argument as follows:
+
+
+```python
+import datasets
+
+cc_by = datasets.load_dataset('BASF-AI/ChemRxiv-Paragraphs', name='cc-by')
+cc_by_nc = datasets.load_dataset('BASF-AI/ChemRxiv-Paragraphs', name='cc-by-nc')
+
+```
