Here’s a concise summary of the project:
Project: OCR-AI-JSON
Goal: Create a system to extract structured data from receipt images using GPT-4 Vision and convert them to standardized JSON format using docling https://github.com/DS4SD/docling-core. With Docling, you can quickly structure and organize data within a document to maximize the efficiency of AI models in understanding and extracting valuable information.
Key Accomplishments:
Core Implementation
- Successful integration with GPT-4 Vision API
- Reliable text extraction from receipt images
- Conversion of unstructured text to structured JSON
- Implementation of both Docling and custom parsing solutions
Data Validation & Quality
- Built a comprehensive validation system for calculations
- Added metrics and analytics for receipt data
- Implemented error detection and reporting
- Established data quality guardrails
Architecture & Features
- Modular design with clear separation of concerns
- Robust error handling and logging
- Support for multiple output formats (text, markdown…
