Abstract:[Purpose/Significance]The research of knowledge graph is at the cutting edge of world information technology,and the basic application of that is of great significance to strengthen the intelligent level of network public opinion analysis and judgment system;[Method/Process]On the basis of related research,this paper discussed the fusion path of knowledge graph in the system,then put forward the network public opinion analysis and judgment system model based on knowledge graph,and discussed the construction practice and application of system;[Result/Conclusion]The research showed that the application of knowledge graph was conducive to the accurate acquisition and intelligent calculation of network public opinion big data,the unification of network public opinion information resources and the enhancement of semantic analysis,the accurate analysis and judgment of risk points and contradiction points of network public opinion,as well as the automatic public opinion reporting,accurate recommendation and decision support.

Key words:knowledge graph;network public opinion;analysis and judgment system;artificial intelligence;fusion path

知識图谱是一种面向人工智能的高级语义建模、知识组织、知识匹配和推理计算技术。在基于知识图谱的网络舆情研判系统中,任务关联的目标,例如事件、机构、地区、人物、行业、企业、产品等与领域情报相关的概念或实体,以及各类概念或实体之间的关系(比如任职、发布等),都在知识图谱中以节点和边的形式结构化。……
