【摘要】：主题演化是网络舆情演化的重要形式,它是一个网络舆情要素的概化过程、主体活性增强的转换过程,也是一个多主题的竞合过程。主题演化既受到网络舆情核心要素的影响,也离不开各种外部因素的作用。主题演化的预警要综合运用定量、定性测量技术,预警指标主要包括原主题的变异水平、外在催化水平、他主题的拉引水平等。在此基础上构建的网络舆情主题演化预警信息工作系统,包括信息捕获与提取模块、分析评估模块和结论通报模块。
[Abstract]:Subject evolution is an important form of the evolution of network public opinion. It is a process of generalization of network public opinion elements, the conversion process of enhancing the activity of the subject, and a competing process of multiple topics. Subject evolution is not only influenced by the core elements of network public opinion, but also by various external factors. Quantitative and qualitative measurement techniques should be used comprehensively in the early warning of theme evolution. The early warning indexes mainly include the variation level of the original theme, the external catalytic level, the pulling and leading level of the other theme, and so on. On this basis, a network public opinion topic evolution early warning information system is constructed, including information capture and extraction module, analysis and evaluation module and conclusion notification module.
