Confidence Score

Overview​

The Confidence Score provides a numerical value between 0 and 1 for each word detected during OCR processing. It represents the OCR engine's confidence in accurately recognizing and extracting each word.

How It Works​

Word-Level Scoring​

Each extracted word is assigned an individual confidence score based on:

  • Text clarity
  • Recognition quality
  • OCR engine heuristics

Independent of Context​

  • The confidence score measures the accuracy of word detection only.
  • It does not reflect the correctness of the field or its context within the document.

Scoring Range​

  • Values range from 0 (no confidence) to 1 (highest confidence).
  • A score above 0.9 is generally considered accurate and reliable.

Use Cases​

Quality Assurance​

  • Identify low-confidence words for manual review or correction.
  • Ensure data quality in sensitive or high-accuracy workflows.

Automated Processing​

  • Trigger fallback workflows (e.g., reprocess or flag data) when scores fall below a set threshold.

Highlighting Low Confidence Areas​

  • Visual tools can display low-score regions to help users spot errors quickly.

Notes​

  • Confidence scores do not indicate whether a word fits semantically or structurally in the document.
  • They are strictly based on how accurately the OCR engine recognized the visual text.

Response with Confidence Score​

This response includes both the parsed data and a version enriched with confidence scores for each extracted field.
