What Is MTPE?

Machine translation post-editing services — what agencies need to know

Machine translation post-editing — MTPE, sometimes written PEMT — is the professional process of reviewing and correcting the output of a machine translation engine to bring it up to a defined quality level. As neural machine translation (NMT) engines have become standard in agency workflows, MTPE has moved from a niche service to a core production method for high-volume Indonesian content.

The fundamental distinction between post-editing and human translation from scratch is cost and speed, not quality ceiling. Full post-editing (FPE) of good NMT output, by an experienced post-editor with domain depth, reaches the same standard as human translation — because at that point the process is human translation, with the MT draft serving as a starting point rather than a blank page. Light post-editing (LPE) targets a lower quality threshold intentionally: understandable and accurate, but not polished.

For Indonesian, the quality of MT output varies significantly by domain, formality register, and text type. Legal, financial, and technical Indonesian routinely exposes the structural and terminological limits of general-purpose engines. A post-editor without deep domain knowledge and bilingual proficiency in Indonesian cannot reliably catch or correct these errors. The value of MTPE lies entirely in the expertise of the person doing the editing.

ISO 18587:2017 — Translation services

The international standard covering post-editing of machine translation output specifies requirements for the process, full post-editing, and light post-editing levels. It defines competencies required of post-editors and quality benchmarks for each level. All MTPE work delivered under this service is aligned with ISO 18587.

Why a sworn translator for MTPE? Indonesian MT output routinely contains errors that only surface as wrong to a native professional with domain depth — incorrect register, calqued legal terms, false equivalents in financial or technical vocabulary. A general post-editor catches fluency errors; a sworn domain specialist catches accuracy errors that look fluent. The difference matters for content that will be acted upon.
Post-Editing Levels

Light post-editing vs. full post-editing

ISO 18587 defines two levels of post-editing. Selecting the right level is a project management decision, not an arbitrary preference — it depends directly on how the translated content will be used. Both levels are available for Indonesian–English and English–Indonesian.

ISO 18587 — Level 1

Light Post-Editing

LPE · Lower per-word rate

Light post-editing produces a functionally accurate, comprehensible output. The goal is intelligibility and factual correctness — not stylistic refinement or full publication quality. Errors that change meaning are corrected; awkward phrasing that does not affect understanding is left as is.

  • Correct any translation errors that change meaning
  • Remove obvious mistranslations and omissions
  • Ensure key terminology is correct
  • Fix critical grammar errors that impede understanding
  • Do not restructure sentences for style or flow
  • Do not adapt to a target-language style guide
Suitable for Internal communications, rapid-turnaround informational content, reference documentation, draft review, gist understanding of large volumes.
ISO 18587 — Level 2

Full Post-Editing

FPE · Human-translation standard

Full post-editing brings the translated output to a human-translation standard: accurate, fluent, terminologically consistent, and appropriate in register. The end reader should not be able to distinguish the output from a translation produced from scratch. The MT draft is a productivity tool, not a quality ceiling.

  • Correct all translation errors and omissions
  • Ensure full linguistic and stylistic fluency in Indonesian or English
  • Apply client glossary and style guide throughout
  • Correct register, formality, and cultural adaptation
  • Restructure sentences where the MT output is technically correct but unnatural
  • Format output consistently with the source document
Suitable for Published marketing content, client-facing documentation, legal and compliance materials, financial reports, product descriptions, and any content submitted to official bodies.
Which level do you need? If unsure, the intended use determines the answer. Content that will be published, submitted to a third party, or read by an Indonesian audience representing your brand or client → full PE. Content for internal reference, rapid gist, or draft review purposes → light PE. When in doubt, contact directly — describe the content type and intended use, and the appropriate level will be recommended before any quote is issued.
How It Works

MTPE workflow — step by step

A structured post-editing process ensures consistent quality across projects — whether a single 1,000-word batch or an ongoing high-volume agency workflow with regular deliveries.

  1. Project intake and briefing

    Receive the MT output, source files, client glossary or termbase, style guide, and any domain-specific reference materials. Confirm the MT engine used, post-editing level (LPE or FPE), target quality standard, CAT tool, and delivery format. For ongoing agency projects, a standing brief covering all these parameters is agreed once and applied across batches.

  2. MT output analysis

    Before editing begins, the MT output is reviewed as a whole to identify recurring error patterns — common mistranslations specific to this engine on this content type, systematic register errors, terminology gaps, and formatting issues. This front-loaded analysis prevents the same error from being corrected 40 times in isolation without recognising the pattern, and is particularly important for large batches.

  3. Post-editing in CAT tool

    Editing is carried out segment by segment in the CAT tool — Trados Studio, memoQ, Phrase, or the client's preferred platform — with the source and MT output visible simultaneously. Translation memory leverage is applied throughout: confirmed segments from prior projects avoid redundant re-editing. A glossary is checked against every key term. For full post-editing, every segment is treated as requiring potential rewrite, not just error correction.

  4. QA review and consistency check

    After segment-level editing, a full-document read-through checks consistency across the document: terminology used consistently, register maintained throughout, no formatting anomalies carried over from the MT draft, and all client-specific requirements applied. QA tools built into the CAT environment are run and resolved. Errors introduced during editing — rarer, but possible — are caught at this stage.

  5. Delivery and TM update

    The completed file is returned in the format the agency requires — XLIFF, SDLXLIFF, MQXLIFF, DOCX, or direct commit to the TMS. The translation memory is updated with confirmed post-edited segments, building the leverage bank for the next batch. For clients running NMT with adaptive training, post-edited corrections can be flagged for engine retraining.

Quality Credentials

Why quality Indonesian MTPE
requires domain depth

The output of any MTPE service is bounded by the post-editor's ability to detect and correct errors. For Indonesian, that means sworn translator-level proficiency combined with genuine domain knowledge — not fluency alone.

Register & Formality

Indonesian operates across multiple registers — formal Bahasa Indonesia, everyday Indonesian, Javanese-influenced constructions, and domain-specific registers. MT engines routinely confuse register levels. A post-editor without native-level proficiency cannot reliably detect or correct these errors.

Legal & Financial Terminology

Legal and financial Indonesian contains terms that look equivalent to English but carry different scope under Indonesian law. Sworn translator certification — dual-issued by Universitas Indonesia — is the credential that guarantees terminological accuracy in these domains, not general post-editing training.

Technical Precision

In-house experience at Ford Motor Company and Toyota Motor Asia Pacific built a deep technical lexicon in automotive and engineering Indonesian. MT engines producing technical Indonesian typically perform worst in exactly the specialised sub-vocabularies that domain expertise covers.

When to Use MTPE

Indonesian MTPE services by content type

MTPE is not appropriate for every project type or quality threshold. These are the content categories where Indonesian machine translation post-editing delivers consistent value for agencies and direct clients.

High-Volume Document Translation

Large document sets — regulatory filings, HR policies, operational manuals, product catalogues — where consistent terminology and accuracy matter but volume makes full human translation from scratch cost-prohibitive.

Recommended: Full PE

E-commerce & Product Descriptions

High-SKU product catalogues, marketplace listings, and product descriptions in Indonesian — where NMT produces reasonable drafts but brand voice, natural phrasing, and local consumer tone require professional post-editing.

Recommended: Full PE

Software & Website Localisation

UI strings, help documentation, and marketing pages where MT provides a workable draft and a post-editor handles terminology consistency, string-level issues, and character limit compliance.

Recommended: Full PE

Internal Corporate Communications

Policy documents, internal memos, HR communications, and corporate briefings for Indonesian-speaking staff where functional accuracy is required but the content is not published externally.

Recommended: Light PE

Technical & User Documentation

Engineering specifications, user manuals, and technical guides where MT drafts are accurate on standard terminology but require expert correction on specialised sub-vocabulary and Indonesian technical register.

Recommended: Full PE

Financial & Compliance Documents

Financial reports, compliance summaries, and regulatory disclosures where MT accelerates production but sworn-level accuracy on financial and legal terminology is non-negotiable.

Recommended: Full PE
Why This Service

What a sworn translator
brings to MTPE

The Indonesian MTPE market is dominated by general freelancers without domain credentials. For agencies running quality-sensitive workflows — legal, financial, pharmaceutical, compliance — the post-editor's qualification is as important as the MT engine's output quality.

Sworn translator certification from the Governor of DKI Jakarta, dual legal translation certification from Universitas Indonesia, and 20+ years of in-house institutional experience are not typical MTPE credentials. They are the reason this service is the right choice for agencies whose clients require accuracy above a general fluency threshold.

  1. Government-level certified accuracy
    Sworn translator status means every post-edited translation carries the same professional and legal accountability as a sworn translation — the highest standard under Indonesian law.
  2. Deep domain specialisation
    Legal, financial, technical, and marketing domains — backed by in-house experience at the World Bank, Ford, Toyota, and UOB Bank. Domain errors in MT output are caught precisely because the terminology is actively known, not looked up.
  3. Agency-native workflow
    Trados, memoQ, Phrase, XTM, Smartcat — TM leverage honoured, client glossaries applied from segment one, files returned in the agency's required format. No workflow friction for project managers.
  4. TM leverage discounts honoured
    Standard fuzzy band pricing is honoured. High-repetition batches and TM-heavy projects are priced accordingly. Volume arrangements for ongoing MTPE workflows are available on request.

Common Questions

MTPE — Frequently Asked Questions

Machine translation post-editing is the process by which a professional translator reviews and corrects the output of a machine translation engine to meet a defined quality standard. It is covered by ISO 18587, the international standard for post-editing of machine translation output. MTPE is distinct from translation from scratch: the MT engine produces the initial draft, and the human post-editor corrects accuracy, fluency, terminology, and register. For Indonesian, the quality of MT output varies significantly by domain and text type, making the post-editor's expertise the primary quality determinant.

ISO 18587 defines two levels. Light post-editing (LPE) targets functional accuracy and intelligibility — errors that change meaning are corrected, but stylistic improvement is not required. The output is understandable and factually correct, but may read as machine-translated. Full post-editing (FPE) targets human-translation standard — accurate, fluent, terminologically consistent, and appropriate in register. The intended use determines the appropriate level. Published, client-facing, or officially submitted content requires full PE. Internal reference or gist purposes suit light PE.

Post-editing services are available for output from DeepL, Google Translate (NMT), Microsoft Translator, ModernMT, Amazon Translate, SYSTRAN, Omniscien, and custom NMT engines integrated with Trados GroupShare or other TMS platforms. The engine does not change the post-editing process — errors are corrected against the source, regardless of where they originate.

Indonesian MTPE is priced per source word, with separate rates for light PE and full PE. The rate reflects the post-editing level, domain complexity, and MT engine quality. Translation memory leverage discounts are applied using standard fuzzy match bands — 100% matches and in-context exact matches are typically excluded or significantly discounted. For high-volume ongoing projects, a volume rate or retainer arrangement can be agreed. Contact directly with project details — engine used, content type, approximate word volume, and delivery cadence — for a specific rate proposal.

Yes. Direct login access is supported for Phrase (Memsource), XTM Cloud, Smartcat, Lokalise, Crowdin, and similar cloud-based TMS platforms. For Trados Studio and memoQ-based workflows, SDLXLIFF and MQXLIFF packages are accepted and returned in the same format. The preference is to work in whatever system your project managers already use — no workflow overhead on your end.

No. Sworn and certified translation — required for submission to courts, embassies, immigration authorities, and Indonesian government bodies — must be produced as a human translation under the sworn certification. MTPE, by definition, involves MT output and cannot be certified as sworn translation. If your project or end client requires a sworn or certified translation, please see the Legal & Sworn Translation or Certified Translation service pages.

Post-editing throughput for Indonesian is approximately 2,000–3,000 words per working day for full PE on domain-specific content, and higher for light PE or general content. Actual turnaround depends on MT output quality, domain complexity, and current project queue. For ongoing agency projects with regular delivery cadences, a standing turnaround schedule is agreed at project start. Rush delivery is available for urgent batches — mention your deadline upfront and feasibility will be confirmed with your quote.
