In the first part of the thesis, we investigate two avenues for building low-resource GEC systems.

In the final part, we focus on GEC for non-English languages and investigate strategies for leveraging available sources of noisy data.

With the vast amounts of content currently being produced online, these methods hold the promise of improving human communication by enabling clear and error-free prose.While GEC is a thoroughly studied field in academia, industrial adoption has been limited. Three specific obstacles are particularly holding back wide-spread industrial adoption: current academic GEC systems 1) depend on a lot of expensive data for training the systems; 2) are mostly evaluated on text written by English language learners, leaving the systems’ performance beyond this domain unclear; and 3) are mainly developed for the English language.This thesis presents research into tackling these obstacles, in order to bridge the gap between academic research and industrial use.
