+# The Pile -- PhilPaper (refined by Data-Juicer)
+
+A refined version of PhilPaper dataset in The Pile by [Data-Juicer](https://github.com/alibaba/data-juicer). Removing some "bad" samples from the original dataset to make it higher-quality.
+
+This dataset is usually used to pretrain a Large Language Model.
+
+**Notice**: Here is a small subset for previewing. The whole dataset is available [here](https://dail-wlcb.oss-cn-wulanchabu.aliyuncs.com/LLM_data/our_refined_datasets/pretraining/the-pile-philpaper-refine-result.jsonl) (About 1.7GB).

+## Dataset Information
