Document Association Device for Automatic Content Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document association methods on mobile devices are cumbersome due to small display sizes, requiring users to manually search for relevant portions in secondary documents, and lack efficient automatic linking mechanisms, especially when the author does not embed link information.
Innovation Solution
A document association device that automatically identifies and links relevant portions between documents by comparing content, allowing users to call up associated content from a predetermined portion without affecting the original document content, using a system comprising a document designating unit, dividing unit, relevant portion identifying unit, and associating unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual searching is used to find relevant portions in secondary documents, then users can locate needed information, but the operation becomes complicated and time-consuming due to small display sizes requiring frequent scrolling and rescaling
Solution Approach 1:
The patent applies preliminary action by pre-embedding link information (such as chapter numbers, section headers, or keyword markers) into the secondary document during its creation or preprocessing stage. This allows the viewing device to automatically jump to the relevant portion without requiring manual scrolling or searching, thus resolving the contradiction between locating accuracy and operation simplicity.
2Ease of manufacture
If link information is not embedded by the author, then the original document content remains simple and uncluttered, but the viewer must take considerable trouble to search for and display the relevant portion
Solution Approach 1:
The patent implements self-service by enabling the viewing device to automatically analyze the secondary document's structure (headers, paragraphs, keywords) and identify the relevant portion based on the context from the first document. This automated self-service approach eliminates the need for manual embedding of link information while maintaining fast navigation, thus resolving the contradiction between document creation simplicity and time efficiency.
3Ease of operation
If the relevant portion is automatically detected and linked, then navigation between documents is simplified, but the system complexity increases due to automatic detection and association mechanisms
Solution Approach 1:
The patent uses an intermediary approach by introducing a document association database that stores pre-extracted structural information (chapter numbers, section headers, keyword indices) from secondary documents. This intermediary database acts as a mediator between the viewing device and the full document content, enabling automatic relevant portion detection without requiring the viewing device to perform complex full-text analysis, thus resolving the contradiction between navigation simplicity and system complexity.

AI summary
A document association device includes: a document designating unit configured, to receive designation of a first document and a second document to be referred to from the first document; a dividing unit configured to divide the second document into a plurality of portions; a relevant portion identifying unit configured to compare contents of the respective portions of the divided second document with contents of a predetermined portion of the first document, and identify the portion having the highest degree of association with the predetermined portion among the plurality of portions as a relevant portion; and an associating unit configured to associate the relevant portion of the second document with the predetermined portion of the first document, to enable calling up of the relevant portion from the predetermined portion.
