Document-level Neural Machine Translation with Inter-Sentence Attention
Table 4: Results on TED Talks (Zh-En) dataset with different context sentence size N and context selection
['[BOLD] Context selection', '[ITALIC] N=1', '[ITALIC] N=2', '[ITALIC] N=3', '[ITALIC] N=4', '[ITALIC] N=5']
Moreover, more contextual information by concatenate multiple context attention does not appear beneficial and the BLEU score does not get better with longer context sentence.
