Post-editing
After completing machine translations, you can review and edit results through apost-editing process (advanced tier only). During post-editing, you can comparethe source and machine-translated documents and then make edits to translatedsegments.
If an administrator has set up a post-editing group, you can also request that atranslator review your document.
You can complete as many rounds of edits as you need. Translation Hubonly saves the latest version of the document. To preserve a particular versionof your document, download or export it before starting another round of edits.
Translation memory
If you selected atranslation memory with your initial machinetranslation request, Translation Hub saves any post-edits to thetranslation memory if your administrator has configured it to read-write. If youdidn't select a translation memory, you can still perform a post-edit, butTranslation Hub doesn't store edits for reuse in future translations.
If you're editing a repeating segment, you must edit each one. You can edit onceand then apply your changes globally by re-translating the document with yourtranslation memory. However, re-translating does incur another translation cost.
A read-only translation memory only applies during translation. No post-editsare saved. Only an administrator can update a read-only translation memory,which can help prevent unintended updates to the translation memory.
Edit translations
After you complete a machine translation in an advanced-tier portal, you canreview and edit the translated segments (self edit). You can't modify the sourcedocument.
Go tohttps://translationhub.cloud.google.com/to sign in to a portal.

When you're done with your review, clickSubmit.
The status of your document changes toPost-editing completed
Segment details
During a post-edit, you can select a segment to view its translation details,such as its machine translation quality prediction (MTQP) score, in theSegment detail pane.
- MTQP - MTQP scores predict if the translation output matches the meaning of the source sentence. These scores are machine-learning generated metrics, which serve as a probability of quality and not a guarantee of quality. A higher score predicts a higher probability. You can use these scores to help guide your editing efforts.
Translation Hub provides MTQP scores for the following supported language pairs:
- Arabic (
ar) <-> English (en) - Chinese (
zh) <-> English (en) - French (
fr) <-> English (en) - German (
de) <-> English (en) - Hindi (
hi) <-> English (en) - Italian (
it) <-> English (en) - Japanese (
ja) <-> English (en) - Portuguese (
pt) <-> English (en) - Russian (
ru) <-> English (en) - Spanish (
es) <-> English (en)
Translation Hub doesn't provide MTQP scores for segments that are replaced by translation memory or for custom model translations.
- Arabic (
- TM (translation memory) - If a segment matched an entry in the translation memory, Translation Hub shows the matching source segment and corresponding translation that Translation Hub used.
- Glossary - If a segment had matching glossary terms, Translation Hub shows a list of the source language terms and their corresponding target language terms.
- Translation reviewed - Indicates that a segment has been post-edited.
- N/A - There's no MTQP score for this segment because it was translated by using a custom model or translated to or from an unsupported language.
