  • Refereed, Journal of Natural Language Processing, The Association for Natural Language Processing, Length-constrained Neural Machine Translation using Length Prediction and Perturbation into Length-aware Positional Encoding, Yui Oka; Katsuhito Sudoh; Satoshi Nakamura,

    Neural machine translation often suffers from an under-translation problem owing to its limited modeling of the output sequence lengths. In this study, we propose a novel approach to training a Transformer model using length constraints based on length-aware positional encoding (PE). Because length constraints with exact target sentence lengths degrade the translation performance, we add a random perturbation with a uniform distribution within a certain range to the length constraints in the PE during the training. In the inference step, we predicted the output lengths from the input sequences using a length prediction model based on a large-scale pre-trained language model. In Japanese-to-English and English-to-Japanese translation, experimental results show that the proposed perturbation injection improves the robustness of the length prediction errors, particularly within a certain range.

Since we assumed that an interpreter's attention ability improves with an increase in the number of years of experience of simultaneous interpretation, we divided the participants into two groups based on their simultaneous interpretation experience: experts with more than 15 years of experience (E group; n = 7) and beginners with <1 year (B group; n = 15). We also compared two conditions: simultaneous interpretation (SI) and shadowing (SH). We found a significant interaction in the ITC between years of SI experience (E and B groups) and tasks (SI and SH). This result demonstrates that the number of years of SI experience influences selective attention during interpretation., Jun. 2021, 15, Scientific journal, True, 10.3389/fnhum.2021.581525

Various evaluation metrics have proposed, and among them, BLEU is widely used as the de facto standard metric. BLEU counts N-grams common between reference and hypothesis translation. On the other hand, ROUGE-L counts longest common subsequences. However, these methods have some problems. People give high scores to Rule-based MT (RBMT), but these methods do not, because RBMT tends to use alternative words. Conventional metrics are severe against the difference of words, but people accept them if the translation has the same meaning. Statistical MT (SMT) tends to translate “A because B” as “B because A” in case of translation between Japanese and English. BLEU does not care about global word order, and this severe mistake is not penalized very much. In order to consider global word order, this paper proposes a lenient automatic evaluation metric based on rank correlation of word order. By focusing on only words common between the two translations, this method is lenient with the use of alternative words. The difference of words is measured by precision of words, and its weight is controlled by a parameter. By using submissions of NTCIR-7 & 9’s Patent Translation task, the proposed method outperforms conventional measures in terms of system level comparison., 2014, 21, 3, 421, 444, Scientific journal, 10.5715/jnlp.21.421

  • Grant-in-Aid for Scientific Research on Priority Areas, 2007 - 2008, 19024075, Coinvestigator, 大規模分散並列処理に基づく統計的機械翻訳, Hajime Tsukada; Hideki Isozaki; Taro Watanabe; Akinori Fujino; Jun Suzuki; Katsuhito Sudoh, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research on Priority Areas, NTT Communication Science Laboratories, 9400000, 9400000, 本年度は、(1)階層的な句に基づく翻訳手法の高度化(須藤,渡辺,塚田)、および(2)半教師あり学習に基づく言語情報解析法の研究(鈴木,藤野,磯崎)の二つの課題に取り組んだ。
    研究課題(1)として,本年度はNTTの研究費によって開発した高次元素性を活用した翻訳手法を,評価型ワークショップIWSLT2008のタスクで評価した.昨年度も高次元素性を活用するアプローチでIWSLT2007に参加したが,今年は文脈情報を含むより高度な素性の活用を検討した.昨年度は翻訳デコーダと密に結合した学習器によって,高次元素性を扱ったが今年より柔軟な素性の扱いを優先し,翻訳結果を再順序付けする学習器で高次元素性を扱うアプローチをとった.最終的に、中英チャレンジタスクにおいて,我々は他チームの1/10〜1/100の量の学習データ(対訳コーパス)で、11チーム中,3位相当の成績を達成することができた.
    研究課題(2)としては,昨年度考案した「半教師あり学習法」による固有表現抽出器などのスケーラビリティの確認をさらなる大規模学習データで確認した.昨年度は10億語を超える学習データを利用した実験を行い,その成果は今年度ACL-2008に採録されたが,今年度はデータをさらに増やして40億語近いデータでも実験を行った.その結果,性能がさらに向上することを確認した.この他,NTTの研究費で考案した半教師あり学習に基づく文書分類法を、公開データ(報道記事,NTCIRタスク)で評価し,有効性を確認した., rm:misc
