Automated Document Reference Extraction System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accessing external content referenced in documents is cumbersome, requiring users to manually follow links or search engines, making retrieval tedious.
Innovation Solution
Automated document analysis systems that exploit the inherent layout of structured documents to extract and retrieve referenced external content by correcting artifacts, binarizing images, and analyzing layout to identify regions of interest containing references, allowing for automatic extraction and retrieval of linked content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual processes are used to access external content, then users can control the retrieval process, but the process becomes tedious and time-consuming
Solution Approach 1:
The system automatically extracts references from document images and retrieves external content without requiring user intervention. The automated reference extraction system processes document images, identifies references, and fetches external content autonomously, eliminating the need for manual link following or search engine queries.
Solution Approach 2:
The patent replaces manual mechanical processes (typing URLs, clicking links, using search engines) with an automated computational system that uses image processing, reference detection algorithms, and automated web scraping to retrieve external content, thereby eliminating tedious manual operations.
2Productivity
If automated extraction is implemented, then retrieval efficiency improves, but system complexity increases
Solution Approach 1:
The system divides the complex task of external content retrieval into separate modular components: document image processing, reference extraction, content retrieval, and presentation. This segmentation allows each component to be developed and optimized independently, managing overall system complexity while maintaining high productivity.
