Pre-training text representations have led to significant improvements in many areas of natural language processing. The
quality of these models benefits greatly from the size of the pretraining corpora as long as its quality is preserved. In this
paper, we describe an automatic pipeline to extract massive high-quality monolingual datasets from Common Crawl for
a variety of languages. Our pipeline follows the data processing introduced in fastText (Mikolov et al., 2017; Grave et al.,
2018), that deduplicates documents and identifies their language. We augment this pipeline with a filtering step to select
documents that are close to high quality corpora like Wikipedia
