Machine Translation Quality Evaluation

What is machine translation quality evaluation?
Machine translation (MT) quality evaluation is the quality assessment by native speakers of text that has previously been translated by machine.

Our qualified workers will fix any errors to produce natural, error-free translations. Additional checks include the adherence of instructions or glossaries, the correct usage of voice and style, as well as the selection of the best version of a translation.
