Abstract: With the development of the Internet, the influence of online public opinion on the society has become more and more prominent, and it has been widely concerned by party and government organs and enterprises. In order to effectively enhance the ability of discovery, research and evaluation of network public opinion, this paper studies the monitoring and analysis technology of network public opinion based on situational awareness. Firstly, this paper puts forward the analysis model of network public opinion situational awareness and discusses the technical method of its realization. Then, through the practical application case, the construction method of the indicator system and the realization scheme of the technical system in the network public opinion situational awareness system are elaborated in detail. Based on the integration of multiple public opinion sensation elements, the case system constructs an effective quantitative index system, realizes the state evaluation of network public opinion from a macroscopic point of view, and predicts the development trend of network public opinion under certain conditions. Comprehensive awareness and realtime warning of online public opinion information and events were implemented. Based on this, we can further study the mechanism of linkage with the business and realize the business closed loop of network public opinion monitoring.v

摘要： 随着互联网的发展，网络舆情对社会的影响愈加凸显，日益受到党政机关和企业的广泛关注.为了有效提升网络舆情的发现力、研判力和评估力，研究了基于态势感知的网络舆情监测分析技术.首先提出了网络舆情态势感知分析模型，并探讨了其实现的技术方法.然后通过实际应用案例，具体阐述了网络舆情态势感知系统中指标体系的构建方法和技术系统的实现方案.该案例系统在融合多舆论场舆情要素的基础上，构建了有效的量化指标体系，从宏观的角度实现网络舆情的状态评估，并在一定条件下对网络舆情的发展趋势进行预测，实现了对网络舆情信息和事件的全面感知和实时预警.以此为基础，可进一步研究与业务进行联动的机制，实现网络舆情监测应对的业务闭环.
