Grammatical Error Correction Considering Multi-word Expressions

Abstract

Multi-word expressions (MWEs) have been recognized as important linguistic information and much research has been conducted especially on their extraction and interpretation. On the other hand, they have hardly been used in real application areas. While those who are learning English as a second language (ESL) use MWEs in their writings just like native speakers, MWEs haven’t been taken into consideration in grammatical error correction tasks. In this paper, we investigate the grammatical error correction method using MWEs. Our method proposes a straightforward application of MWEs to grammatical error correction, but experimental results show that MWEs have a beneficial effect on grammatical error correction.
