 ### Swallow Corpus Version 2
 
-We built the Swallow Corpus by extracting high-quality Japanese texts from Common Crawl. In Version 2, we expanded the scope of the Common Crawl collection and modified the pipeline sequence to enable more flexible quality filtering. For Llama 3.1 Swallow v0.2, we further enhanced quality filtering and sampling during training compared to v0.1, resulting in the use of even higher-quality Japanese texts.
