Requirements

Must-Have

  • Native Korean speaker with full command of Hangul, including hanja.
  • Experience in bilingual transcription, translation, editorial work, or AI training data.
  • Exact character-level accuracy.
  • Systematic application of taxonomy across pages.
  • Comfort with unfamiliar layouts like multi-column newspapers and handwritten forms.

Preferred

  • Experience with AI training data: annotation, labeling, grading, or bilingual evaluation.
  • Skills in transcription and localization: MTPE, subtitling, bilingual QA, OCR correction.
  • Document production experience: typesetting, copy-editing, proofreading, or digitization of Korean-language material.
  • Knowledge of script and encoding: Unicode normalization, Korean input methods, Hangul jamo composition, and hanja handling.

Benefits & conditions

  • Annotate structure by identifying and bounding every meaningful region of the page. Assign each a component type and a reading-order index.
  • Record relationships by linking each region to its parent component, such as a figure or table.
  • Transcribe faithfully by reproducing all text exactly as it appears in Hangul, including any hanja and handwritten content. Flag any illegible regions.
  • Capture page metadata, including language, document type, source, page dimensions, and flags for tables, formulas, and handwriting.
  • Review a colleague’s work. Every task is reviewed end-to-end by a second Korean expert.
