Before revision: Following previous work on automatic paraphrasing, we assess the feasibility of improving BLEU(Papineni et al. , 2002) using state-of-the-art neural paraphrasing techniques to generate additional references. We explore the extent to which diverse paraphrases can adequately cover the space of valid translations and compare to an alternative approach of generating paraphrases constrained by MT outputs.
