融合公众情绪的上海城市形象感知分析OA
Urban image perception of Shanghai based on public emotions
城市形象对于促进城市健康发展十分重要,纳入公众参与的城市形象研究十分必要.本文将公众情绪纳入城市感知研究框架,利用基于迁移学习的中文全词覆盖双向编码模型(BERT-WWM)的情感分类方法、情感倾向指数和语义分析模型,对上海签到原创微博进行分析,探索上海城市形象感知.结果表明:①由城市情感形象感知分析可知,上海整体城市情感形象积极,市民在城市商业、文旅、生活活跃区域更易产生不同城市情感形象感知;②由城市认知形象感知分析可知,使上海产生积极认知形象的源头主要是城市文旅;使上海产生消极认知形象的源头主要是城市天气、城市交通、生活压力等;非常规时事热点事件会在短期内得到大规模关注,从而影响该时间段内的城市认知形象.融合公众情绪的上海城市形象感知分析既能更好地了解某一阶段市民对所在城市获得感、幸福感、安全感的真实表达,又能更好地为今后长期的城市规划与治理提供合理的参考.
Urban image is important for promoting the healthy development of the city,so it is necessary to incorporate the research on urban images with public participation.By incorporating public emotions into the urban image perception research framework,this article utilized sentiment classification methods based on bidirectional encoder representations from transformers-whole word mask(BERT-WWM),sentiment index,and semantic analysis models to analyze original check-in Weibo posts in Shanghai and explore the urban image perception of Shanghai.The result illustrates that:① According to the analysis of urban image perception based on emotions,the overall urban image of Shanghai is positive,and citizens are more likely to have different urban image perceptions in urban commerce,culture and tourism,and active life areas.② According to the analysis of urban image perception based on cognition,the main sources of the positive cognitive image of Shanghai are the culture and tourism;the main sources of the negative cognitive image of Shanghai are the weather,traffic,and life pressure.Unconventional hot events will receive large-scale attention in a short period of time,thus affecting the urban cognitive image within this period of time.The urban image perception analysis of Shanghai based on public emotions can not only provide a better understanding of citizens'genuine expressions of satisfaction,happiness,and security regarding their location at a certain time but also help to offer reasonable references for long-term urban planning and governance in the future.
