Research on the Construction of Knowledge Graph and Trusted Sharing Mechanism of English Academic Literature Based on Blockchain and Cloud Computing

Abstract

This study offers a new solution towards building and sharing academic knowledge graphs in a trustless manner by leveraging blockchain technology and cloud computing infrastructure. The distributed framework improves the construction of knowledge graphs and provides an efficiency gain of 41.2% versus traditional systems. With blockchain technology, secure and authenticated information sharing can be achieved, while also mitigating the possibility of copyright and user exploitation infringement with a 99.98% successful transaction verification rate and response time for authorized requests at less than 50 milliseconds. The system’s multi-faceted efficacy has been verified through experimental assessment wherein the system, on full operational load, managed to remain constantly above 4,150 transactions per second. Knowledge extraction is sustained at >90% precision and recall across all academic domains. Combining blockchain with cloud computing for academic knowledge management proves to be more beneficial without compromising security or reliability, thus the study confirms the feasibility of the framework. This research helps in the formulation of advanced trusted academic knowledge sharing systems along with enabling further design improvements on consensus mechanisms, natural language processing methods, and cross-chain integration.
