What Is Post-Editing?

Post-editing is the process of reviewing and refining machine-generated translations to improve accuracy, fluency, and overall quality. A human translator corrects errors, adjusts phrasing, ensures consistency, and enhances readability while leveraging the initial output from an MT engine. 

This process allows companies to benefit from the speed and cost-effectiveness of MT while ensuring a level of quality that aligns with professional standards. Post-editing is widely used in industries such as e-commerce, legal, medical, technical documentation, and corporate communication. 

The Difference Between Light Post-Editing, Full Post-Editing, and Full Human Translation

Not all post-editing is the same. Depending on the quality requirements, budget, and intended use of the translation, companies can choose between light post-editing, full post-editing, or full human translation. 

1. Light Post-Editing (LPE)

Light post-editing involves minimal human intervention. The goal is to make the machine-translated text understandable and free of major errors, but not necessarily polished for style or tone. 

Key Characteristics of Light Post-Editing:
  • Quick correction of critical errors (e.g., mistranslations, missing words, major grammar issues) 
  • No significant changes to sentence structure or style 
  • No correction of terminology and consistency 
  • Retains the basic MT output while ensuring readability 
  • Suitable for internal documents, drafts, and content where perfection is not required 
When to Use Light Post-Editing:
  • Translating internal company reports or informal communication 
  • Understanding the general meaning of a document 
  • When speed and cost-effectiveness are the main priorities 

2. Full Post-Editing (FPE)

Full post-editing is a more comprehensive process that ensures the translation is not only accurate but also terminologically correct, fluent, stylistically appropriate, and culturally adapted. 

Key Characteristics of Full Post-Editing:
  • Corrects all grammatical, spelling, and syntax errors 
  • Improves readability and ensures natural-sounding language 
  • Adapts terminology to industry-specific requirements 
  • May involve some restructuring of sentences for clarity 
  • Suitable for client-facing content, official documentation, and professional communication 
When to Use Full Post-Editing:
  • Customer-facing websites and marketing materials 
  • Legal, medical, or technical documents requiring precision 
  • Business reports and publications 

3. Full Human Translation (FHT)

Unlike post-editing, full human translation does not rely on machine-generated content. A professional translator translates the text from scratch, ensuring the highest level of quality, nuance, and cultural adaptation. 

Key Characteristics of Full Human Translation:
  • No reliance on MT; the translator interprets the text independently 
  • Highest accuracy and fluency 
  • Maximum cultural adaptation and stylistic refinement 
  • Best for creative content and sensitive legal/medical texts 
When to Use Full Human Translation:
  • Creative advertising or high-impact marketing content 
  • Legal contracts where precision is paramount
