TER
Translation Error Rate
Translation Error Rate (TER) is a metric for automatic evaluation of machine translation that calculates the number of edits required to change a machine translation output into one of the references.
TER is defined as the minimum number of edits needed to change a hypothesis so that it exactly matches one of the references, normalized by the average length of the references.
