Cross-lingual Transfer Learning for Grammatical Error Correction

no code implementations COLING 2020 Ikumi Yamashita, Satoru Katsumata, Masahiro Kaneko, Aizhan Imankulova, Mamoru Komachi

Cross-lingual transfer learning from high-resource languages (the source models) is effective for training models of low-resource languages (the target models) for various tasks.

Grammatical Error Correction Using Pseudo Learner Corpus Considering Learner's Error Tendency

no code implementations ACL 2020 Yujin Takahashi, Satoru Katsumata, Mamoru Komachi

To address the limitations of language and computational resources, we assume that introducing pseudo errors into sentences similar to those written by the language learners is more efficient, rather than incorporating random pseudo errors into monolingual data.

Stronger Baselines for Grammatical Error Correction Using Pretrained Encoder-Decoder Model

2 code implementations24 May 2020 Satoru Katsumata, Mamoru Komachi

In this study, we explore the utility of bidirectional and auto-regressive transformers (BART) as a generic pretrained encoder-decoder model for GEC.

Automated Essay Scoring System for Nonnative Japanese Learners

no code implementations LREC 2020 Reo Hirao, Mio Arai, Hiroki Shimanaka, Satoru Katsumata, Mamoru Komachi

In this study, we created an automated essay scoring (AES) system for nonnative Japanese learners using an essay dataset with annotations for a holistic score and multiple trait scores, including content, organization, and language scores.

TMU Transformer System Using BERT for Re-ranking at BEA 2019 Grammatical Error Correction on Restricted Track

no code implementations WS 2019 Masahiro Kaneko, Kengo Hotate, Satoru Katsumata, Mamoru Komachi

Thus, it is not straightforward to utilize language representations trained from a large corpus, such as Bidirectional Encoder Representations from Transformers (BERT), in a form suitable for the learner{'}s grammatical errors.
