Solution Overview
Problem
Conventional OCR techniques struggle to achieve high accuracy in real-time environments, particularly with images of poor quality, mixed character types, and unstructured documents, necessitating manual review and reducing automation efficiency.
Innovation Solution
A system that preprocesses documents, encodes them into text strings, and uses target text strings for comparison to enhance data extraction accuracy, employing algorithms tailored for specific character recognition and metadata classification, followed by a rules processor workflow for verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional OCR techniques are used for data extraction, then the system can process documents, but the accuracy is insufficient especially for poor quality images, mixed character types, and unstructured documents
Solution Approach 1:
The system performs preliminary actions by preprocessing documents before OCR processing. This includes encoding documents into text strings, identifying target text strings based on user submissions, and preparing metadata for classification. These preliminary actions enable the subsequent OCR processing to focus on specific areas and improve overall accuracy while maintaining real-time processing capability
Solution Approach 2:
The system applies local quality by selecting and processing only the relevant portions of documents that contain target text strings. Instead of processing entire documents uniformly, the system identifies and focuses on specific regions containing the required information, improving accuracy for difficult-to-read areas while maintaining efficient processing speed
2Extent of automation
If conventional OCR techniques are used, then documents can be processed, but manual review is required which reduces automation efficiency
Solution Approach 1:
The system implements feedback mechanisms where extracted data is validated against user submissions and processing terms. The system provides feedback about extraction accuracy and can automatically correct or flag items for review, increasing automation level while minimizing the time required for manual verification through intelligent feedback loops
Solution Approach 2:
The system performs self-service by automatically validating extracted data against provided user submissions and processing terms. It autonomously determines when manual review is necessary and handles routine verification tasks independently, maximizing automation while reducing manual intervention time through self-verification capabilities
3Reliability
If the system processes documents with high accuracy requirements in real-time, then verification can be performed, but the complexity of the processing system increases
Solution Approach 1:
The system segments the complex verification process into distinct manageable modules: document encoding, target text string identification, OCR processing, data validation, and rules processor workflow. Each module handles a specific aspect of verification, improving reliability while managing complexity through modular architecture where each component can be optimized independently
