AI Technical Summary
Existing technologies for electronic record management in highway construction projects suffer from problems such as inaccurate metadata linking, discrepancies between records and project progress, poor long-term readability of design documents, and easy chain breaks during multi-party transfer and signing.
Metadata is linked using a semantic similarity algorithm based on a pre-built knowledge graph of highway engineering sub-items, the status of engineering nodes is checked in real time and early warnings are triggered, the design document version is automatically identified and converted into a long-term storage format, and an immutable signature chain is generated using blockchain notarization technology.
It achieves high-precision metadata linking, ensuring that archives are synchronized with project progress, guaranteeing the long-term readability of documents, and building an immutable trust chain, thereby enhancing the legal validity and management credibility of electronic archives.
