DuTongChuanDuTongChuan, abbreviation of Baidu simultaneous interpreting in Chinese Pinyin. : Context-aware Translation Model for Simultaneous Interpreting
Table 5: Comparison between machine translation and human interpretation. The interpretation reference consists of a collection of interpretations from S, A and B. Our model is trained on the large-scale corpus.
['Models', 'Translation Reference BLEU', 'Translation Reference Brevity Penalty', 'Interpretation Reference (3-references) BLEU', 'Interpretation Reference (3-references) Brevity Penalty']
We concatenate the translation of each talk into one big sentence, and then evaluate it by BLEU score. Moreover, the length of interpretations are relatively short, and results in a high length penalty provided by the evaluation script. The result is unsurprising, because human interpreters often deliberately skip non-primary information to keep a reasonable ear-voice span, which may bring a loss of adequacy and yet a shorter lag time, whereas the machine translation model translates the content adequately. We also use human interpreting results as references.
