+Preprocessed version of [WikiSplit](https://arxiv.org/abs/1808.09468).  
+Since the [original WikiSplit dataset](https://huggingface.co/datasets/wiki_split) was tokenized and had some noises, we have used the [Moses detokenizer](https://github.com/moses-smt/mosesdecoder/blob/c41ff18111f58907f9259165e95e657605f4c457/scripts/tokenizer/detokenizer.perl) for detokenization and removed text fragments.  
+For detailed information on the preprocessing steps, please see [here](https://github.com/nttcslab-nlp/wikisplit-pp/src/datasets/common.py).  
+This preprocessed dataset serves as the basis for [WikiSplit++](https://huggingface.co/datasets/cl-nagoya/wikisplit-pp).
