Dataset Card for OLM August 2022 Common Crawl

Cleaned and deduplicated pretraining dataset, created with the OLM repo here from 20% of the August 2022 Common Crawl snapshot.

Note: last_modified_timestamp was parsed from whatever a website returned in it's Last-Modified header; there are likely a small number of outliers that are incorrect, so we recommend removing the outliers before doing statistics with last_modified_timestamp.
