Initiative Overview
A sophisticated document intelligence platform engineered for high-stakes processes, combining advanced optical character recognition with intelligent data extraction capabilities. The solution transforms unstructured documents into actionable data while maintaining the highest standards of accuracy, auditability, and data integrity required for democratic institutions.
Methodology
Intelligent Preprocessing: Advanced computer vision pipeline featuring automatic deskewing, noise reduction, contrast optimization, and template alignment for heterogeneous document standardization
Precision Extraction: Custom-trained layout detection models for field zone identification, combined with high-accuracy OCR engines and sophisticated post-processing including regex validation and entity recognition
Data Architecture: PostgreSQL enterprise data warehouse with structured schema design, secure image asset management, and comprehensive metadata tracking for full document lifecycle traceability
Quality Assurance: Multi-layered validation including confidence scoring, business rule verification, duplicate detection, and human-in-the-loop review queues for critical data validation
Multilingual Capabilities: French-primary with configurable character set support and locale-specific format handling for names, dates, and identification numbers.
