Diversity by Phonetics and its Application in Neural Machine Translation
Table 7: Translation results in BLEU[%] for ZH-EN.
['Coding', 'ZH-EN']
We apply Pinyin [pinyinwubipackage], and Pinyin segmented into letters, and Wubi encoding [pinyinwubipackage]. We achieve significant improvement over the baseline by adding auxiliary information: 0.87 BLEU points with Pinyin, 1.68 BLEU points with Pinyin in letters, and 1.11 BLEU points with Wubi, respectively. Randomly clustering on Chinese characters and words both improve the baseline with 1.49 and 1.47 BLEU points, respectively, a more significant improvement than that of the K-Means clustering.
