ICDAR 2026 HIPE-OCRepair Competition on LLM-Assisted OCR Post-Correction for Historical Documents
arXiv:2607.08143v1 Announce Type: new Abstract: We present the results of HIPE-OCRepair-2026, an ICDAR competition on LLM-assisted OCR post-correction of historical documents. OCR post-correction remains a long-standing challenge in digital heritage: large-scale collections of digitized documents are affected by legacy OCR errors, while re-digitization at scale remains impractical. Large language models (LLMs) offers a major opportunity to revisit this challenge, yet their effectiveness across languages, document types, and noise conditions - and their tendency to hallucinate - remains insuffi
The proliferation of Large Language Models (LLMs) and increased focus on digital preservation of historical archives are converging, prompting new methods for addressing long-standing OCR challenges.
Improving the accuracy of digitized historical documents via LLM-assisted post-correction will unlock vast datasets for research and AI training, preserving cultural heritage and enabling new analytical possibilities.
Previously impractical large-scale re-digitization or manual correction of historical texts becomes feasible with LLM assistance, significantly enhancing data quality and accessibility for heritage institutions and researchers.
- · Digital humanities researchers
- · Archival institutions
- · LLM developers (fine-tuning opportunities)
- · Cultural heritage sector
- · Traditional OCR post-correction service providers (without LLM integration)
- · Projects relying solely on low-quality historical OCR data
Significantly higher quality and quantity of historical document datasets become available for analysis.
New AI models trained on these cleaner historical datasets could uncover previously hidden patterns in history, sociology, or economics.
The enhanced accessibility of historical knowledge could reshape public understanding of past events and cultural evolution.
