(2018), whose results indicate that combining different methods in normalization can be beneficial, we can indeed get a minor boost for the results of the highest accuracy NMT model if we first try to correct with the above described Word2Vec method and then with NMT, we can increase the overall accuracy to 59.5%.
there is no increase if we invert the order and try to first correct with the NMT and after that with the Word2Vec model.
