Indirect Hyperlinks for Linkrot-Resilient Content Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hyperlink systems face challenges in reliably navigating to intended content due to linkrot, where hyperlinks become inaccessible or point to outdated content, and users face difficulties in distinguishing between multiple archival versions of documents to find the intended content.
Innovation Solution
The implementation of indirect hyperlinks that point to both the live-web original resource and a stable archival copy, using a secondary document with automated checks for the presence of intended content, and incorporating time stamps in fragment identifiers to facilitate reliable content identification and archival record matching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hyperlinks are used to navigate to documents, then navigation convenience is improved, but link reliability deteriorates due to linkrot and document modifications
Solution Approach 1:
The patent introduces an intermediary system that mediates between the hyperlink and the target document. This intermediary maintains a database of document versions and automatically resolves hyperlinks to the correct archival version, even when the original document location changes or the document is modified. The intermediary acts as a buffer that preserves link reliability while maintaining navigation convenience.
Solution Approach 2:
The system performs preliminary actions by pre-archiving document versions and pre-processing hyperlinks to include version identification information. Before linkrot occurs or documents are modified, the system has already created and stored alternative versions with unique identifiers, enabling automatic resolution when the original link fails.
2Reliability
If multiple archival versions of documents are stored, then content availability is improved, but user ability to find intended content deteriorates due to difficulty in distinguishing versions
Solution Approach 1:
The patent applies the principle of visual differentiation by incorporating distinctive version identifiers that clearly distinguish between multiple archival versions. These identifiers act like unique 'colors' or markers that allow users to immediately recognize and differentiate between versions without having to examine detailed content differences.
Solution Approach 2:
The system provides feedback to users about the availability and characteristics of different archival versions. When a hyperlink is resolved, the system returns information about which version was accessed and why, allowing users to verify they reached the intended content and understand the versioning system.
3Measurement precision
If automated checks for content presence are implemented, then navigation accuracy is improved, but system complexity increases due to secondary documents and verification mechanisms
Solution Approach 1:
The system implements self-service mechanisms where the archival system automatically performs content verification and version resolution without requiring complex external validation. The secondary documents and verification mechanisms are designed to autonomously check content presence and resolve links, reducing the perceived complexity for users while maintaining high navigation accuracy.
Data Source
AI summary
A computer-implemented system and method for navigation on a communication network to robustly locate, retrieve and display information. In response to a few user inputs, a hyperlink is created that provides efficient and robust access to original resources and also to alternative resources for originally intended content. Intended content may comprise the whole of or only parts of document resources, which may be affected by linkrot or content modification. Such created links and hyperlinks can be checked to determine if they cannot be followed or if they can be followed but originally intended content is missing or altered. Then intended content can be accessed from alternative resources including archival resources and non-archival live resources.
