ABBYY OCR (FineReader / FlexiCapture): Guardrails and Fix Patterns

You are in a sub-page of DocumentAI_OCR.
To reorient, go back here:

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

Use this page when ABBYY OCR powers ingestion of scanned PDFs, complex layouts, forms, or multilingual documents.
ABBYY is enterprise-grade, but still prone to schema drift, field misalignment, and unstable table anchors.


Open these first


Core acceptance

  • ΔS(question, retrieved) ≤ 0.45
  • Coverage ≥ 0.70 across fields and tokens
  • λ convergent on three paraphrases and two seeds
  • Form fields ≥ 95% aligned with schema contract

Typical breakpoints → structural fix


Fix in 60 seconds

  1. Enforce field schema: require field_id, bbox, confidence, revision_id.
  2. Compute ΔS on critical fields (e.g. total_amount, invoice_date).
  3. Apply λ probes with different template libraries.
  4. Clamp instability with BBAM and log coverage.
  5. Rebuild index if ΔS ≥ 0.60 persists.

Copy-paste LLM guard prompt

I uploaded TXTOS and the WFGY Problem Map.

OCR provider: ABBYY (FineReader / FlexiCapture).  
Symptoms: field drift, unstable tables, ΔS ≥ 0.60.

Steps:
1. Identify failing layer (contracts, chunking, retrieval).  
2. Point to the WFGY fix page.  
3. Return JSON:  
   { "fields_checked": [...], "answer": "...", "ΔS": 0.xx, "λ_state": "<>", "next_fix": "..." }  
Keep it reproducible and auditable.
