| 摘 要： | 目的/意义] 区别于单一维度的情感强度测度，基于情感语义空间的食品安全舆情情感分析从立体空间角度探析情感的细粒度表征及情感焦点，对政府及有关部门提升舆情治理水平具有重要意义。方法/过程] 运用PAD情感模型构建情感语义空间，以2018年食品安全舆情为例，一方面，将情感词映射至情感语义空间，根据位置判别情感词多维情感强度；另一方面，根据情感语义空间的表现形式划分情感层次，探寻不同情感指向特征。结果/结论] 多维情感语义空间中，食品安全舆情情感的自我认知层愉悦度较高，表明公众认为自身对食品安全有较好的认知；舆情中社会发展和民生民意空间呈现明显的负向情绪，且网民在表达该类情感时的神经生理激活水平较高，应引起政府高度重视。食品安全舆情中的意见领袖对他人情感有较强的影响力，政府应加强与该领域意见领袖的沟通与引导。

| Abstract: | Purpose/Significance] Different from a single-dimensional measure of sentiment intensity,the food safety public opinion sentiment analysis based on sentiment semantic space analyzes the fine-grained representation of sentiment and sentiment focus from the perspective of three-dimensional space,which is of great significance for the government and relevant departments to improve the level of public opinion governance.Method/Process] The PAD model was used to construct the emotional semantic space.Taking the food safety public opinion events in 2018 as an example,on the one hand,emotional words were mapped to the emotional semantic space,and calculated multi-dimensional emotional intensity of emotional words based on location;on the other hand,the expression form divided the emotion level and explored different emotion-oriented characteristics.Result/Conclusion] In the multi-dimensional emotional semantic space,the self-awareness level of food safety public sentiment was high,indicating that the public believed that they had a better understanding of food safety;and the social development and people's livelihood involved had a significant negative development trend.Moreover,the level of neurophysiological activation of netizens in expressing such emotions should be highly valued by the government.Opinion leaders in food safety public opinion had a strong influence on the emotions of others,and the government should strengthen communication and guidance with opinion leaders in this field. |
