为舆情管控部门对舆情事件判断水平、反应能力和应急处置能力的提升提供信息保障和辅助决策支撑,基于GIS的舆情传播推演系统在舆情处置行动中,不但可提供城市基本地理信息、人文信息,还可针对不同用户需求提供舆情影响空间分析、人员分析、传播过程分析、管控效果分析和舆情演变态势分析等功能,并实现舆情演变信息地图显示、图表输出等多种形式的表达。文中就系统的技术体系、关键分析推演模型以及系统的实现进行了研究,并研发了实验系统进行了验证。
In order to provide information support and supporting decision-making support to public opinions and control departments on judging the level of public opinion events, their response ability and the ability to deal with emergencies, the public opinion broadcast system based on GIS can not only provide basic urban geographic information, humanistic information, It can also provide functions such as spatial analysis, personnel analysis, communication process analysis, management and control effect analysis and public opinion evolution trend analysis for different user needs, as well as various expressions such as public opinion evolution information map display and chart output. In this paper, the system technology system, the key analysis deduction model and the realization of the system are studied, and the experimental system is developed.
