This dataset combines wikipedia20220301.en and 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 it's faster to iterate over sequentially than when using dataset.shuffle. 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.
