| This dataset combines [wikipedia20220301.en](https://huggingface.co/datasets/wikipedia) and [bookcorpusopen](https://huggingface.co/datasets/bookcorpusopen), | |
| and splits the data into smaller chunks, of size ~820 chars | |
| (such that each item will be at least ~128 tokens for the average tokenizer). | |
| The order of the items in this dataset has been shuffled, | |
| meaning you don't have to use `dataset.shuffle`, | |
| which is slower to iterate over. | |
| The logic only splits on spaces, so the chunks are likely to be slightly larger than 820 chars. | |
| The dataset has been normalized into lower case, with accents and non-english characters removed. | |
| Items with less than 200 chars or more than 1000 chars have been removed. | |
| This dataset is processed for convenience, at the expense of losing some percentage of the tokens due to truncation, | |
| (assuming the training minibatches are truncated to 128 tokens). | |
