Has the author made sure he's using the exact same set of word embeddings as utilized by the authors of that paper? Are they trained on exactly the same corpus with the same parameters? Do the md5 hashes match? This could be cheating... Or it could be a case of model mismatch. I'm left without a clear reason to prefer one explanation over the other.
