Abstract
We present Charles University submissions to the WMT22 General Translation Shared Task on Czech-Ukrainian and Ukrainian-Czech machine translation. We present two constrained submissions based on block back-translation and tagged back-translation and experiment with rule-based romanization of Ukrainian.
Our results show that romanization only has a minor effect on the translation quality. Further, we describe Charles Translator, a system developed in March 2022 as a response to the migration from Ukraine to the Czech Republic.
Compared to our constrained systems, it did not use romanization and used some proprietary data sources.
