Page-grounded extraction review
Compare the converted Markdown and JSON with the source PDF page by page. Report missing headings, merged columns, broken equations, lost footnotes, incorrect reading order and OCR uncertainty. Quote only the minimum text needed to locate each defect and give the PDF page number. Do not repair content from general knowledge.
Known pitfalls
- Reading order can be wrong in multi-column layouts.
- Equations, footnotes and spanning tables require visual comparison with the PDF.
- OCR may produce plausible but incorrect numbers.
- Do not discard the original PDF or page references after conversion.
Evidence
- Docling 2.117.0 is the latest release returned by the official GitHub repository and PyPI on the verification date. source (2026-08-02)
