%description
An interface to the 'fastText'
<https://github.com/facebookresearch/fastText> library for efficient
learning of word representations and sentence classification. The
'fastText' algorithm is explained in detail in (i) "Enriching Word Vectors
with subword Information", Piotr Bojanowski, Edouard Grave, Armand Joulin,
Tomas Mikolov, 2017, <doi:10.1162/tacl_a_00051>; (ii) "Bag of Tricks for
Efficient Text Classification", Armand Joulin, Edouard Grave, Piotr
Bojanowski, Tomas Mikolov, 2017, <doi:10.18653/v1/e17-2068>; (iii)

Edouard Grave, Piotr Bojanowski, Matthijs Douze, Herve Jegou, Tomas
Mikolov, 2016, <arXiv:1612.03651>.
