A hub to **triage and repair noisy text inputs** from scanned PDFs, images, HTML scraping, or parser drift.
Use this folder when the document looks fine to the eye but retrieval or reasoning keeps failing.

## Orientation: what each page does
| Page | What it solves | Typical symptom |
|------|----------------|-----------------|
| [Layout, Headers, Footers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OCR_Parsing/layout_headers_and_footers.md) | Remove noise from margins and repeated text | Answers reference “page 3 footer” instead of body |
| [Tokenization & Casing](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OCR_Parsing/tokenization_and_casing.md) | Normalize Unicode, case, and hyphens | `E-mail` ≠ `Email`, half-width/full-width mismatch |
| [Tables & Columns](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OCR_Parsing/tables_and_columns.md) | Preserve table schema and cell order | Numbers drift across columns |
| [Images & Figures](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OCR_Parsing/images_and_figures.md) | OCR and align captions | Figure text missing or attached to wrong section |
| [Scanned PDFs & Quality](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OCR_Parsing/scanned_pdfs_and_quality.md) | Handle skewed/blurred pages | Whole sections unreadable to OCR |
| [Multi-language & Fonts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OCR_Parsing/multi_language_and_fonts.md) | Normalize mixed scripts | Chinese/English tokens split or duplicated |

## When to use
- OCR tables or citations look visually correct but answers miss the right section.
- Code blocks or math collapse after parsing.
- Mixed-language documents behave inconsistently.
- Special characters or hyphen splits break tokens.
- Headers or section anchors disappear during export.
---
## FAQ
**Why does OCR “look fine” but retrieval fails?**
Because tokenization and indexing see hidden breaks (Unicode variants, line merges, wrong anchors) that humans overlook.
**What is the most common root cause?**
Headers/footers leaking into the body and breaking ΔS alignment.
**Do I need to retrain embeddings after fixing?**
No — most fixes are structural (schema/normalization). Re-indexing with the same embeddings is enough.
---
## Acceptance targets
- ΔS(question, retrieved) ≤ 0.45 for three paraphrases.
- Coverage ≥ 0.70 for the target section.
- λ_observe convergent across two seeds.
- Human audit shows no missing headers, captions, or broken tables.
---
## Fix in 60 seconds
1. **Ground-truth one page**
Pick one Q/A pair and keep a screenshot baseline.
2. **Measure ΔS**
Log ΔS(question, retrieved) and ΔS(retrieved, anchor).
3. **Probe λ_observe**
Ask for cite-first. If citation fails but free explanation works, drift confirmed.
4. **Patch minimally**
- Re-run OCR with line/table fences
- Normalize casing and Unicode
- Preserve anchors, math, captions
- Drop low-confidence spans and export with `{section_id, page_no, char_span}`
