HERIT mitigates temporal bias for Hanja-to-English historical translation via RAG pseudo-labeling

DAMI-Lab · hf · 2026-11-06

DAMI-Lab introduces HERIT, adapting machine translation for Hanja historical archives by mitigating temporal bias. The pipeline: (1) a Proposer generates multiple drafts using task instructions and multilingual dictionary examples; (2) retrieval draws historical priors from Hanja-Kor and Hanja-Eng corpora; (3) a Fusor merges drafts with retrieved context into the final sentence; (4) 2-stage fine-tuning combines synthetic and human-labeled data. This improves accuracy across time periods, unlocking global access to remaining Hanja historical texts.
