摘要
[目的/意义]利用事理图谱对重大突发事件下网络舆情UGC进行分析,可以更好地呈现舆情事件之间的因果演化过程及演化路径,从而为重大突发事件舆情疏导和管控提供一定的指导.[方法/过程]构建重大突发事件网络舆情UGC事理图谱模型,给出规则模板和句法模式,提取明确因果事件对和模糊因果事件对,结合重大突发自然灾害河南暴雨救援事件下的微博舆情分析,从而实现事理图谱构建;通过K-means聚类将相似度较高的舆情事件泛化,构建抽象事理图谱.[结果/结论]研究结果表明,利用本文构建的重大突发事件网络舆情UGC事理图谱模型,可以对网络舆情的因果事件关联关系进行分析,从而揭示重大突发事件网络舆情发展过程中的关键事件.事理图谱可以帮助更好地对重大突发事件中的网络舆情演化过程进行分析,抽象事理图谱可以帮助进一步分析网络舆情UGC的演化路径.
[Purpose/Significance] Using the event evolution graph to analyze the UGC of network public opinions under major emergencies, it can better present the causal evolution process and evolution path between public opinion events, thereby providing certain guidance for public opinion channeling and management and control of major emergencies. [Method/Process] This study constructed the UGC event evolution graph model of network public opinion of major emergencies, generated rule templates and syntactic patterns, and extracted event pairs with clear causality and event pairs with ambiguous causality, combined with the Weibo public opinion topic under the heavy rain rescue event in Henan, a major sudden natural disaster, to realize the construction of event evolution graph. The public opinion events with high similarity were generalized by K-means clustering algorithm, and the abstract event evolution graph was constructed. [Result/Conclusion] The study results show that using the UGC event evolution graph model of network public opinions of major emergencies constructed in this paper, the causal event correlation of network public opinions can be analyzed, so as to reveal the key events in the development process of network public opinions for major emergencies. Evolution graph model can help to better analyze the evolution process of network public opinions in major emergencies, abstract event evolution graph can help to further analyze the evolution path of network public opinion UGC.
