基于“林松龄”社会热点事件,本研究对中国网民在“猫扑”论坛中的回帖文本进 行了分析。为了通过应用情感分析方法进一步明确中国网民针对争议性热点事件的线上 行为特征,本研究将研究对象分成两个维度,分别是网民个人化表达行为及网民回复性 讨论行为,并主要通过提取相应回帖文本的长度、标点、观点与话题的关系等信息以及 测量回帖文本的情感极性,来分别得出个人化表达行为与回复性讨论行为的特征。研究 发现,网民个人化的表达多趋向于以较简短的话语表达极其负面、激进、极端的情绪, 且通常指向政府或相关权力机构;而就网民之间的讨论过程而言,绝多数参与者之间都 表现为对抗式关系;被卷入争论的网民则表现得更具攻击性, 从而争论发展到最后多偏 离原有话题而演变成相互之间的人身攻击。

Based on the heatedly discussed social incident - “six policemen in Harbin beat a young man to death”, this study concentrates on analyzing the text of relevant comments posted by Chinese netizens on the forum of “Mop”. In order to figure out how the Chinese netizens behave online when discussing prominent and controversial social issues, the author has utilized the method of sentiment analysis and divided the research object into two dimensions - the netizens’ individual expression and the responded-to discussion among them. By respectively examining the length, punctuation and opinion-topic relation of the forum replies and measuring their sentiment polarities, the results revealed that most netizens’ self-oriented replies tend to express negative, radical and extreme emotions toward the government and authorities with only a few words. During the process of online discussion, the relationship among participants is more likely to grow into antagonism. Moreover, the netizens involved in debates tend to behave in a more aggressive manner, thus most debates eventually deviate from the principal contradiction and turn into personal attacks.
