AI translation review: check terminology, numbers and units before fluency
Use an original short exercise to review terminology, numbers, units and dates. Record observed output; the exercise does not establish translation performance.
Fluent wording can still change meaning, quantities or conditions. This guide separates review into terminology, numbers, units, dates and omissions. Its steps and sample are original editorial designs based on previously checked product-purpose sources. No text was submitted for translation in this review.
From original text to a translation you can check
Prepare text and terminology
Specify source and target languages and key terms. The official entry describes text translation, language selection and document translation; exact language pairs and plan conditions still need checking.[1]
Review a short sample
Compare the original and observed translation side by side for names, numbers, units, dates and negation. Start with one passage before a long document.[1]
Keep sources and edit notes
Record omissions and edits against the original, and arrange human review for important text. A glossary feature description does not verify your account eligibility or allowance.[1]
1. Prepare input and a review checklist
Start from the checked translation tool entry, select text translation and a target language. Check document and text workflows separately; features in another product form do not establish current-page entitlements.[1]
- Submit only the synthetic text needed for the exercise, without real orders, accounts or private material.
- List key terms and intended translations before submission. Without a glossary feature, keep a local list for manual comparison.
- Record source and target languages, input version and date. Do not assume automatic language detection is always correct.
2. Begin with one synthetic passage
Original exercise: “The sample contains 1,200 units. Each unit weighs 0.75 kg. Deliver it by 3 December 2026. Do not include replacement parts.” It is not an order or real business record. Check that quantity, unit, deadline and negation survive.[1]
- Translate this passage separately and record the tool’s observed output yourself.
- For a Chinese target, the intended meaning is 1,200 units, 0.75 kilograms per unit, delivery by 3 December 2026 and no replacement parts.
- This intended meaning is a manual review reference. No tool translation was obtained or recorded in this review.
3. Compare each item, beyond fluency
| Check | What to compare | What to do if it differs |
|---|---|---|
| Terminology | Consistent contextual translations of unit and replacement parts | Return to context and your terminology list. |
| Numbers and units | Preservation of 1,200, 0.75 and kg with the correct referents | Check decimal and thousands separators, units and what each quantity describes. |
| Date | 3 December 2026 retains the same calendar date | Use an explicit year, month and day to avoid regional short-date ambiguity. |
| Negation | Do not include still means exclusion | Inspect omitted or reversed negations, limits and exceptions. |
| Completeness | All four sentences are represented | Mark omissions and added information before retranslating or editing. |

Keep a record of each check, original passage, observed translation, issue and revision. One short input cannot establish accuracy, industry reliability or performance across language pairs.[1]
4. Extend to longer text and files
- After key conditions survive the sample, review long text passage by passage and maintain terminology consistency.
- Before file translation, check supported formats, editability, size and current plan conditions; a purpose description does not verify these constraints.
- Compare tables, pagination, footnotes and omissions with the original; record actual formatting changes.
- Arrange review by someone with relevant language and domain knowledge for important text. Do not publish unchecked content as an accurate translation.
Verification scope
The existing official-purpose source was checked on 24 October 2026. It describes text translation, language selection, document entry points and a glossary feature. This article was written and editorially reviewed on 3 November 2026; the dates are recorded separately.[1]
No login, file upload, translation run, glossary-eligibility check or cost measurement was performed. The passage, intended meaning and checklist are original exercise designs, not observed product outputs. Prices, language coverage, regions, file entitlements and performance need confirmation for actual use.[1]
