Document Thumbnail Generation via Asset Extraction and Cross-Source Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current thumbnail generation methods for documents do not convey human-readable information effectively, especially for text-heavy documents without images, leading to users needing to individually access each document to obtain specifics, and result in similar thumbnails appearing indistinguishable.
Innovation Solution
A method involving a document analysis engine that generates thumbnails by identifying and weighting key assets (words, images) from a document, then using these assets to retrieve matching assets from a second source, combining them to create a thumbnail that conveys document specifics and distinguishes between similar documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional thumbnail generation methods are used (reducing document size), then the thumbnail can be generated quickly and easily, but the thumbnail does not convey meaningful information about document specifics and similar documents appear indistinguishable
Solution Approach 1:
The patent extracts key assets (words, images, sentences) from the full document to create a condensed representation. The document analysis engine identifies and extracts the most representative elements from the source document, which are then used to generate the thumbnail. This extraction process ensures the thumbnail conveys meaningful information while avoiding the complexity of processing the entire document.
Solution Approach 2:
The patent changes the parameters of thumbnail generation by transitioning from simple geometric reduction to a content-based approach. The system adjusts parameters such as asset selection criteria, weighting factors for different document elements, and synthesis methods to optimize both information conveyance and generation efficiency.
2Loss of information
If users want to obtain specifics of each document, then they must individually access each document, but this increases time consumption and reduces productivity
Solution Approach 1:
The patent performs preliminary analysis of document content during the thumbnail generation process. The document analysis engine pre-identifies and extracts key assets, creates weighted representations, and synthesizes meaningful thumbnails before users need to view the documents. This preliminary action allows users to obtain document specifics information upfront through the thumbnail without requiring individual document access.
3Loss of information
If text-heavy documents without images are used, then the document content can be dense with information, but the generated thumbnails become indistinguishable and fail to convey document uniqueness
Solution Approach 1:
The patent applies local quality by treating different document elements (words, images, sentences) with different weights and processing priorities. The document analysis engine identifies specific local regions or elements within the text-heavy document that are most representative and assigns them higher weights. This allows the thumbnail generation to focus on distinctive local features rather than treating all content uniformly, thereby differentiating between similar text-heavy documents.
Solution Approach 2:
The patent introduces asymmetry in the thumbnail generation process by applying non-uniform weighting to different assets based on their relevance and representativeness. Instead of treating all text elements equally, the system creates an asymmetric distribution of importance across document elements, which results in thumbnails that reflect the unique characteristics of each document even when they are text-heavy.
Data Source
AI summary
A method for generating thumbnail is provided. In one embodiment, a summary of a first document is generated. The summary includes a first asset (e.g. words, images or sentences). The first document is a first source. The first asset is used to obtain a second asset (e.g. words, images or sentences) from a second source. A thumbnail of the first document is generated using the first asset and the second asset. An apparatus for substantially performing the method as described herein is also provided.
