Emotional Analysis of International Relations Topics in Media Think Tanks:Principle Analysis,Tool Construction and Application Exploration

【目的/意义】媒体型智库作为国家话语窗口承载着国际交流的重要职能。探讨媒体型智库国际关系话题的情感分析,对评价媒体型智库在国际场域舆论引导力具有重要意义。【方法/过程】首先结合情感认同理论,对比舆论引导和情感转化路径对研究进行原理解析,进而通过文本挖掘和文献阅读获取201篇国际关系智库文章和30个种子词,运用SO-PMI算法构建国际关系情感词典作为情感分析的支撑工具。最后选取6家智库进行应用探索,依托情感趋同原理得到媒体型智库在国际关系话题上的舆论引导力排名。【结果/结论】最终通过情感认同视角分析媒体型智库国际关系,构建的情感词典较通用词典具有独有领域的优越性,对国际关系领域情感分析评测效果有可靠性。【创新/局限】本文从媒体型智库舆论引导过程的结果入手,引入情感认同构建理论基础,提出的测评方案为情感分析赋能国际关系研究提供新视角。局限在于词典的构建部分,训练集的数据还可拓展,使词典准确率进一步提升。

【Purpose/significance】As a national discourse window,media-type think tank bears an important function of international communication.Sentiment analysis under the topic of international relations can provide a scientific and comprehensive understanding of the development of international relations,which is of great significance to think tank development and exploration of international relations.【Method/process】Firstly,by combining the theory of emotional identity and comparing the guidance of public opinion and the path of emotional transformation,this paper analyzes the principle of the research,and constructs the research tool.Through text mining and literature reading,201 international relations think tank articles and 30 seed words are obtained,and the SO-PMI algorithm is used to construct the international relations emotion dictionary.Finally,six think tanks were selected for application exploration to obtain the ranking of public opinion guiding power of think tanks.【Result/conclusion】Finally,the author analyzes the international relations of media think tanks from the perspective of emotional identity.Compared with the general dictionary,the constructed emotional dictionary has the advantage of its own field,and the evaluation effect of emotion analysis in the field of international relations is reliable.【Innovation/limitation】Starting from the results of the media think tank's public opinion guidance process,this paper introduces the theoretical basis of emotional identity construction,and proposes an evaluation scheme to provide a new perspective for the study of international relations empowered by emotional analysis.The limitation lies in the construction part of the dictionary.The data of the training set can be expanded to further improve the accuracy of the dictionary.
