    abstract  = {Since the introduction of large language models in Natural Language
    Processing, large raw corpora have played a crucial role in Computational Linguistics.
    However, most of these large raw corpora are either available only for English or not
    available to the general public due to copyright issues. Nevertheless, there are some
    examples of freely available multilingual corpora for training Deep Learning NLP
    models, such as the OSCAR and Paracrawl corpora. However, they have quality issues,
    especially for low-resource languages. Moreover, recreating or updating these corpora
    is very complex. In this work, we try to reproduce and improve the goclassy pipeline
    used to create the OSCAR corpus. We propose a new pipeline that is faster, modular,
    parameterizable, and well documented. We use it to create a corpus similar to OSCAR
    but larger and based on recent data. Also, unlike OSCAR, the metadata information is
    at the document level. We release our pipeline under an open source license and
    publish the corpus under a research-only license.},

    Natural Language Processing (NLP), recent years have seen a proliferation of large,
    Web-mined text datasets covering hundreds of languages. We manually audit the quality
    of 205 language-specific corpora released with five major public datasets (CCAligned,
    ParaCrawl, WikiMatrix, OSCAR, mC4). Lower-resource corpora have systematic issues: At
    least 15 corpora have no usable text, and a significant fraction contains less than
    50{\%} sentences of acceptable quality. In addition, many are mislabeled or use
    nonstandard/ambiguous language codes. We demonstrate that these issues are easy to
    detect even for non-proficient speakers, and supplement the human audit with automatic
    analyses. Finally, we recommend techniques to evaluate and improve multilingual
    corpora and discuss potential risks that come with low-quality data releases.},

    performance of OSCAR-based and Wikipedia-based ELMo embeddings for these languages on
    the part-of-speech tagging and parsing tasks. We show that, despite the noise in the
    Common-Crawl-based OSCAR data, embeddings trained on OSCAR perform much better than
    monolingual embeddings trained on Wikipedia. They actually equal or improve the
    current state of the art in tagging and parsing for all five languages. In particular,
    they also improve over multilingual Wikipedia-based contextual embeddings
    (multilingual BERT), which almost always constitutes the previous state of the art,
    thereby showing that the benefit of a larger, more diverse corpus surpasses the
    cross-lingual benefit of multilingual embedding architectures.},

    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.},
