AI translation post-editing by linguists

What Is MTPE?

The machine translation post-editing (MTPE) is a process in which a qualified human linguist reviews and improves the AI-translated content. The editor checks meaning, grammatical issues, and context against the source text and your requirements.

MarsHub provides MTPE translation services for businesses that process multilingual content without merely relying on machine output. Depending on the content’s purpose, we can focus on essential corrections for internal use or comprehensive editing for publication-ready content.

Why AI Translation Needs Human Editors

Machine translation is quick, and it can produce multilingual drafts quickly, but a fluent sentence is not always accurate. AI can misinterpret context, use the wrong industry term, or produce wording that may sound unnatural to local readers.

Post-editors review the output against the source text and other project requirements. They fix contextual meaning, terminology issues and ensure the translation is appropriate for its intended audience.

Types of MTPE Services

The right approach to post-editing depends on the type of source material, target audience, sensitivity of content, and required quality level.

Light Post-Editing of Machine Translation

Light post-editing focuses more on important corrections so readers can understand the meaning behind it. It is suited to appropriate internal communications, reference material, and other content where stylistic polish is not the main priority.

Full Post-Editing of Machine Translation

Full post-editing addresses accuracy, terminology, grammar, fluency, and style to meet the quality requirements for the audience. It is more appropriate for content that will be published or shared externally, subject to content-specific review.
