Knowledge Graph Tracing and Query System Based on Blockchain

In order to solve the problem that the personal rights and interests of knowledge map producers cannot be protected, this paper proposes a query system for the management and traceability of knowledge maps based on blockchain technology. This system contains the following modules: a user information module, a knowledge map production and production information record module, a knowledge map comparison and calculation module, a revenue distribution module and an information query module. The system provides a transparent and reliable unified information platform; it can trace the entire production, updating and circulation process of knowledge graphs and protect the privacy information of producers.
