Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated classification tools for life science documents lack comprehensive understanding due to limited analysis of text, document construct, and image elements, leading to ambiguity and reduced classification accuracy.
Innovation Solution
A computer-implemented tool combining text, document construct, and image analyses to enhance classification accuracy by leveraging spatial relationships, formatting, and additional metadata, using machine learning and AI to differentiate document classes and provide real-time feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional automated classification tools use only text analysis, then the system complexity is low, but classification accuracy is reduced due to ambiguity
Solution Approach 1:
The patent combines text analysis, document construct analysis, and image analysis into a unified automated classification system. The text analysis module processes document content, the document construct analysis module analyzes spatial relationships and formatting, and the image analysis module processes graphical elements. These three analysis modules work synergistically to provide comprehensive document understanding and improve classification accuracy beyond what text analysis alone can achieve.
Solution Approach 2:
The patent extends the classification approach from one dimension (text content only) to multiple dimensions by incorporating document construct analysis (spatial relationships, formatting, layout) and image analysis (graphical elements, charts, diagrams). This multi-dimensional analysis enables the system to disambiguate between document classes that have similar text content but differ in structural or visual characteristics.
2Measurement precision
If multiple analysis modules are used to improve classification accuracy, then classification accuracy improves, but processing time increases
Solution Approach 1:
The system performs preliminary analysis by first conducting text analysis to identify the document type and key characteristics. Based on the text analysis results, the system can selectively apply document construct analysis and image analysis only when needed, rather than always processing all three analysis types. This reduces unnecessary processing time while maintaining high classification accuracy for documents where text analysis is sufficient.
3Productivity
If text analysis is used alone, then processing speed is fast, but classification accuracy is reduced due to ambiguous text
Solution Approach 1:
The document construct analysis module serves as an intermediary that bridges text analysis and final classification decisions. When text analysis produces ambiguous results, the document construct analysis module analyzes spatial relationships, formatting, and layout characteristics to provide additional context that resolves ambiguity. Similarly, the image analysis module acts as an intermediary for documents where graphical elements provide critical classification information not present in the text.

AI summary
A computer-implemented tool for automated classification and interpretation of documents, such as life science documents supporting clinical trials, is configured to perform a combination of raw text, document construct, and image analyses to enhance classification accuracy by enabling a more comprehensive machine-based understanding of document content. The combination of analyses provides context for classification by leveraging relative spatial relationships among text and image elements, identifying characteristics and formatting of elements, and extracting additional metadata from the documents as compared to conventional automated classification tools.
