This paper describes the joint submission of the QT21 projects for theEnglish->Latvian translation task of the EMNLP 2017 Second Conference on Machine Translation (WMT 2017). The submission is a system combination whichcombines seven different statistical machine translation systems provided by thedifferent groups. The systems are combined using either RWTH’s system combination approach,or USFD’s consensus-based system selection approach. The final submissionshows an improvement of 0.5 BLEU compared to the best single system onnewstest2017.
