Underwriting Rule Generation Workflow (TOC-Based + Textract)

+ +
+

Key Improvements

+
    +
  • TOC-Based Extraction: Systematic section-by-section analysis ensures complete policy coverage
    • +
  • Section Boundary Detection: Uses 3 strategies (number+title, number-only, title-only) to accurately extract section content
    • +
  • 30-char Threshold: Filters out pure headers to prevent LLM hallucination
    • +
  • Anti-Hallucination Prompts: Explicit instructions to only extract policies from actual content
    • +
  • Batch Textract Queries: 30 queries per batch due to AWS limits
    • +
  • Two-Pass Textract Parsing: Maps QUERY blocks to QUERY_RESULT blocks via Relationships
    • +
  • Deterministic Caching: Temperature=0 + content hash ensures identical PDFs generate identical rules
    • +
  • Container-Per-Ruleset: Separate Docker containers for each rule set (optional, enabled by default)
