The state-of-the-art neural machine translation engines available on LivoLink provide near-human fluency and accuracy in an unprecedented way, reducing costs and workload for multilingual content.

However, the choice to use machine translation must take into account the possibility of errors in the final product. In areas such as medical and technical translation, for example, mistranslation can be critical.

Post-editing of machine translated content represents an intermediate solution between human translation and pure machine translation. It is often called MTPE, PEMT or simply post-editing. The essence of post-editing is to check machine translation for accuracy. It is used to create content that conveys the message in a way that is understandable to its potential audience, but may not feel completely natural. Post-editing is suitable for the creation of multilingual website content, e-commerce translation, translation of in-house documents, translation of chatbots and other ERP-type content. Post-editing offers economies: it takes less time than translating from scratch, reducing project costs.

MTPE in action

What is the difference between human translation and post-editing?

You should be aware that post-editing of machine translation generally does not provide the same level of quality as 100% human translation.

The language industry organisation TAUS  ( distinguishes between two "levels" of machine translation post-editing: "Good enough" and "Human-like". The differences are summarised in this table:

“Good Enough” MTPE
“Similar to Human” MTPE
Use as much of the raw MT output as possible.
Aim for semantically correct translation.
Aim for grammatically and syntactically correct translation.
Ensure that no information has been accidentally added or omitted.
Edit any offensive, inappropriate or culturally unacceptable content.
Ensure that basic rules regarding spelling are complied with.
Ensure that basic rules regarding punctuation and hyphenation are complied with.
Ensure that key terminology is correctly translated and that untranslated terms belong to the client’s list of “Do Not Translate” terms”.
Implement corrections that are of a stylistic nature only.
Wedle uznania lingwisty
Restructure sentences solely to improve the natural flow of the text.
Wedle uznania lingwisty
Ensure that formatting is correct.

The key difference between 'Good enough' and 'Human-like' post-editing is that ‘Good enough’ does not aim for a flawless text. Under the TAUS ( guidelines for post-editing, "the text may sound as if it has been generated by a computer, the syntax may be slightly unusual, the grammar may not be perfect, but the message is accurate."
