A translator post-edits a file pretranslated with MT. How to calculate total PEM - between MT proposal and the final translator's version - if the translator changes segment more than once?
I can imagine at least two cases:
- Segment was visited two times, once changed, once not. This is trivial - the PEM should be taken from the record where translation was changed.
- Segment visited two times and changed a bit each time. This is non-trivial
