# Washi (a kind of traditional Japanese paper)

This dataset is sampled from a subset of ja (Japanese) sourced from [uonlp/CulturaX](https://huggingface.co/datasets/uonlp/CulturaX). 
Utilizing DSIR (Data Selection for Language Models via Importance Resampling), 
documents closest to the Japanese subset of csebuetnlp/xlsum and systemk/aozorabunko_chunked 
(cleaned data from the Aozora Bunko collection, containing modern Japanese literature in the public domain) were selected, 
comprising approximately 5% of the corpus.

We have noted a qualitative leap in the quantity of low-quality Japanese datasets with the release of several multilingual datasets. 
However, traditional data cleaning methods for Japanese, based on blacklists and rules, continue to produce significant noise.

We speculate that, particularly in cases where fine-tune from predominantly English-focused Large Language Model (LLM), 
the quality of data outweighs its quantity. Hence, we have created this dataset to validate this hypothesis.
