This is the old OSCAR pipeline, if you are looking for the upcoming pipeline please take a look at the Ungoliant project.

An asynchronous concurrent pipeline for classifying Common Crawl based on fastText's pipeline.

For more info see our paper here.

If you want to download OSCAR you can do it here.

Note: For the moment the downloader part of the pipeline is not available as it is still experimental, it will be open sourced in a future release.

  abstract  = {Common Crawl is a considerably large, heterogeneous multilingual corpus comprised of crawled documents from the internet, surpassing 20TB of data and distributed as a set of more than 50 thousand plain text files where each contains many documents written in a wide variety of languages. Even though each document has a metadata block associated to it, this data lacks any information about the language in which each document is written, making it extremely difficult to use Common Crawl for monolingual applications. We propose a general, highly parallel, multithreaded pipeline to clean and classify Common Crawl by language; we specifically design it so that it runs efficiently on medium to low resource infrastructures where I/O speeds are the main constraint. We develop the pipeline so that it can be easily reapplied to any kind of heterogeneous corpus and so that it can be parameterised to a wide range of infrastructures. We also distribute a 6.3TB version of Common Crawl, filtered, classified by language, shuffled at line level in order to avoid copyright issues, and ready to be used for NLP applications.},
