摘要
[目的/意义]为深化区块链技术在网络舆情中的应用,推动网络舆情溯源体系的构建与完善,提高突发舆情风险管理的科学性与预见性。[方法/过程]本文基于态势感知理论和区块链技术,构建了多社交平台网络舆情溯源体系,采用区块链和IPFS的双存储机制进行舆情数据的海量存储,利用智能合约对风险舆情进行监控预警,基于内容标识符CID和事件ID实现网络舆情的精准溯源。[结果/结论]完善了区块链视域下突发公共卫生事件网络舆情溯源体系,提高了多平台间舆情风险的可溯源度与可预测度,为政府相关监管部门提供了精准的舆情预警与决策支持。
[Purpose/Significance]To deepen the application of blockchain technology in network public opinion,promote the construction and improvement of the network public opinion traceability system,and improve the scientific and predictable risk management of sudden public opinion.[Method/Process]Based on situation awareness theory and blockchain technology,this paper built a multi-social platform network public opinion traceability system,adopted the dual storage mechanism of blockchain and IPFS for mass storage of public opinion data,used smart contracts for monitoring and early warning of risky public opinion,and realized accurate traceability of network public opinion based on content identifiers CID and event ID.[Result/Conclusion]The network public opinion traceability system for public health emergencies from the perspective of blockchain has been improved,the traceability and predictability of public opinion risks among multiple platforms have been improved,and accurate public opinion early warning has been provided for relevant government regulatory departments and decision support.
