Hiroki Asano, Masato Mita, Tomoya Mizumoto, Jun Suzuki · 2019
We introduce the AIP-Tohoku grammatical error correction (GEC) system for the BEA-2019 shared task in Track 1 (Restricted Track) and Track 2 (Unrestricted Track) using the same system architecture.Our system comprises two key components: error generation and sentence-level error detection.In particular, GEC with sentence-level grammatical error detection is a novel and versatile approach, and we experimentally demonstrate that it significantly improves the precision of the base model.Our system is ranked 9th in Track 1 and 2nd in Track 2.
