Evaluating Chinese-Vietnamese Low-resource Machine Translation with Back Translation
Table 3: Results of word-based SMT
['Directions Settings', 'zh\\rightarrowvi BLEU', 'zh\\rightarrowvi METEOR', 'vi\\rightarrowzh BLEU', 'vi\\rightarrowzh METEOR']
As shown of the results in bottom left corner of table 3, the results of 60k and 100k Vietnamese data are almost the same, even though the data size varies by half a million. On the contrary, as the data sizes increase, the scores have been fluctuating and showing downward trends. Finally, different with character-based results, the scores of vi-zh here are much lower zh-vi ones.
