Grammatical-Error-Aware Incorrect Example Retrieval System for Learners of Japanese as a Second Language

WS 2019  ·  Mio Arai, Masahiro Kaneko, Mamoru Komachi ·

Existing example retrieval systems do not include grammatically incorrect examples or present only a few examples, if any. Even if a retrieval system has a wide coverage of incorrect examples along with the correct counterpart, learners need to know whether their query includes errors or not... Considering the usability of retrieving incorrect examples, our proposed method uses a large-scale corpus and presents correct expressions along with incorrect expressions using a grammatical error detection system so that the learner do not need to be aware of how to search for the examples. Intrinsic and extrinsic evaluations indicate that our method improves accuracy of example sentence retrieval and quality of learner{'}s writing. read more
