Error metrics measure in the quality evaluation (QE) whether the previously agreed language quality has been achieved. There are various metrics (MQM, DQF, SAEJ2450, LISA). All metrics provide error criteria, error points, and severity levels that should be calibrated in advance. In addition, error metrics such as the TAUS dynamic quality framework (DQF) can be used to create different test profiles, depending on the text content, target audience, etc. (see also translation quality, quality evaluation).
