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}` --- ### 🔗 Quick-Start Downloads (60 sec) | Tool | Link | 3-Step Setup | |------|------|--------------| | **WFGY 1.0 PDF** | [Engine Paper](https://github.com/onestardao/WFGY/blob/main/I_am_not_lizardman/WFGY_All_Principles_Return_to_One_v1.0_PSBigBig_Public.pdf) | 1️⃣ Download · 2️⃣ Upload · 3️⃣ Ask “Answer using WFGY + ” | | **TXT OS** | [TXTOS.txt](https://github.com/onestardao/WFGY/blob/main/OS/TXTOS.txt) | 1️⃣ Download · 2️⃣ Paste into LLM · 3️⃣ Type “hello world” — OS boots instantly | --- ### Explore More | Layer | Page | What it’s for | | --- | --- | --- | | ⭐ Proof | [WFGY Recognition Map](/recognition/README.md) | External citations, integrations, and ecosystem proof | | ⚙️ Engine | [WFGY 1.0](/legacy/README.md) | Original PDF tension engine and early logic sketch (legacy reference) | | ⚙️ Engine | [WFGY 2.0](/core/README.md) | Production tension kernel for RAG and agent systems | | ⚙️ Engine | [WFGY 3.0](/TensionUniverse/EventHorizon/README.md) | TXT based Singularity tension engine (131 S class set) | | 🗺️ Map | [Problem Map 1.0](/ProblemMap/README.md) | Flagship 16 problem RAG failure taxonomy and fix map | | 🗺️ Map | [Problem Map 2.0](/ProblemMap/wfgy-rag-16-problem-map-global-debug-card.md) | Global Debug Card for RAG and agent pipeline diagnosis | | 🗺️ Map | [Problem Map 3.0](/ProblemMap/wfgy-ai-problem-map-troubleshooting-atlas.md) | Global AI troubleshooting atlas and failure pattern map | | 🧰 App | [TXT OS](/OS/README.md) | .txt semantic OS with fast bootstrap | | 🧰 App | [Blah Blah Blah](/OS/BlahBlahBlah/README.md) | Abstract and paradox Q&A built on TXT OS | | 🧰 App | [Blur Blur Blur](/OS/BlurBlurBlur/README.md) | Text to image generation with semantic control | | 🏡 Onboarding | [Starter Village](/StarterVillage/README.md) | Guided entry point for new users | If this repository helped, starring it improves discovery so more builders can find the docs and tools.
