A quality measurement (QM) is a measure for the ongoing assessment of the language quality.
This is particularly important when using machine translation .
Here, the speeds of post editing are measured using productivity measurement methods (e.g. time-to-edit, see also TAUS, DQF) .
So you know when to retrain or replace engines.
Ideally, quality measurements are automatically carried out during translation and the post editing process (see also post editing, translation quality).
