摘　　要：针对官方媒体在引导网络舆情中公众情感未能积极引导、难以把握舆情重点的问题,提出构建舆情主题战略图以辅助官方媒体舆情引导;该方法以公众议论和官方报道中的舆情主题为分析单元,融合LDA主题建模和知网情感词典进行舆情主题发现和情感二分类,并通过定义舆情的主题情感值(TE)、主题使用程度(TU)和主题关注程度(TA)三个定量化评价舆情主题的指标,提出构建公众舆情主题战略图和舆情主题供需战略图两个子图.最后结合“齐齐哈尔体育馆坍塌”热点网络舆情事件进行验证.In view of the problem that the official media fails to actively guide public sentiment and grasp the key points of public opinion in guiding online public opinion,this paper proposes to construct a public opinion topic strategic diagram to assist the official media in guiding public opinion.In this method,the public opinion topics in public discussion and official reports are taken as the analysis unit,and the LDA topic modeling and Hownet sentiment dictionary are integrated to find public opinion topic discovery and sentiment classification,and by defining three quantitative indicators of public opinion topic sentiment value(TE),topic usage degree(TU)and topic attention degree(TA)of public opinion,two sub-graphs of public opinion topic strategic diagram and public opinion topic supply and demand strategic diagram are proposed.Finally,it was verified in combination with the hot network public opinion event of"Qiqihar Stadium Collapse".
