Fixing OCR misclassification of hierarchical document section titles
💡Learn how to solve common OCR structural labeling errors in complex legal documents using sequence modeling.
⚡ 30-Second TL;DR
What Changed
DeepSeek-OCR provides high-quality text but inconsistent structural labeling for hierarchical legal documents.
Why It Matters
Improving structural extraction from PDFs is critical for legal tech and document automation workflows. A robust post-processing layer can significantly reduce manual verification time for complex regulatory documents.
What To Do Next
Start with a rule-based heuristic system using coordinate features before training a CRF, as legal document numbering is often highly structured.
Key Points
- •DeepSeek-OCR provides high-quality text but inconsistent structural labeling for hierarchical legal documents.
- •Proposed solutions include using a CRF or BiLSTM-CRF to re-classify lines based on spatial and formatting features.
- •The developer is weighing the complexity of sequence labeling models against simpler heuristic-based rule systems.
