Document Processing System for Automated Data Extraction and Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document processing systems fail to automatically extract and validate data fields from digitized paper documents with dissimilar layouts and complex structures, requiring manual intervention due to limitations in optical character recognition (OCR) and lack of analysis of document layouts.
Innovation Solution
A document processing and validation system that classifies digitized documents based on their intended tasks, applies specific processing rules, uses machine learning techniques to identify and extract data fields, and assigns confidence scores for validation, reducing the need for human intervention by selecting significant documents and eliminating duplicates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If optical character recognition (OCR) is used to extract data from digitized documents, then text can be converted from images, but the system cannot accurately handle documents with dissimilar layouts and complex structures, requiring manual intervention
Solution Approach 1:
The system segments the document processing task into multiple stages: document classification, layout analysis, field identification, and data extraction. Each stage handles specific aspects of the document, allowing the system to manage dissimilar layouts and complex structures effectively while maintaining automation.
Solution Approach 2:
The system performs preliminary document classification and layout analysis before data extraction. By analyzing the document structure and identifying fields in advance, the system prepares the extracted data according to the specific document type, improving accuracy for documents with varying layouts.
2Measurement precision
If manual intervention is used to handle documents with dissimilar layouts, then data extraction accuracy can be maintained, but productivity decreases and manual effort increases
Solution Approach 1:
The system dynamically adapts its processing approach based on document classification. Different processing rules and field identification strategies are applied according to the document type, allowing automated handling of various layouts while maintaining accuracy through context-specific methods.
Solution Approach 2:
The system changes processing parameters based on document type classification. By adjusting extraction strategies, field locations, and validation rules according to the specific document category, the system maintains high accuracy across diverse document formats without requiring manual intervention for each type.
3Loss of information
If all documents in a collection are processed in detail, then comprehensive data extraction is achieved, but processing time increases significantly for large document collections
Solution Approach 1:
The system performs preliminary document classification and significance assessment before detailed processing. By identifying and prioritizing significant documents, the system processes only the most relevant documents in detail while handling others more efficiently, reducing overall processing time while maintaining data completeness for critical documents.
Solution Approach 2:
The system applies partial processing to document collections by focusing detailed analysis on significant documents identified through classification. Less critical documents receive streamlined processing, allowing the system to handle large collections efficiently while ensuring comprehensive data extraction where it matters most.
Data Source
AI summary
Data extraction and automatic validation from digitized documents in non-editable formats is disclosed. Paper documents are digitized or converted into formats suitable for storage on computers or other digital devices. The digitized documents are classified into one of a plurality of document types and based on the document type, document processing rules are selected for analyzing the digitized documents to enable data extraction and automatic validation. The positions and values of the data fields in the digitized documents are obtained using machine learning techniques. The data field values are automatically validated and assigned confidence scores. Data fields with low confidence scores are flagged for manual review.
