Using Machine Translation to Localize Task Oriented NLG Output
Scott Roy, Cliff Brunk, Kyu-Young Kim, Justin Zhao, Markus Freitag, Mihir Kale, Gagan Bansal, Sidharth Mudgal, Chris Varano
arXiv, 2021
paper /
Developed a set of methods to localize at scale a task-oriented natural language application like the Google Assistant using neural machine tranlsation. The proposed approach includes development of an appropriate sequence model with an encoding scheme of structured input, fine-tuning on in-domain translations, and automatic error detection.
