%description
    FastText is an open-source, free, lightweight C++ library and
    companion CLI for (1) Word Representation Learning (via Skipgram and
    CBOW methods) and (2) Text Classification. It works on standard,
    generic hardware. Models can later be reduced in size to even fit on
    mobile devices. FastText is better than the classical Word2Vec in
    two major aspects: (1) FastText uses N-grams instead of whole words
    and hence can also work on rare words and (2) FastText can generate
    vectors for Out-Of-Vocabulary (OOV) words (words not present in the
    dictionary during training).
