舆情分析

基于地名识别、关键词提取、城市舆情主题词库等自然语言处理技术，舆情分析模型能够自动识别城市舆情文本中的地名、舆情事件类型、关键词等。并结合舆情相似识别技术，合并重复舆情事件，分别按区域、按主题自动统计各类舆情事件的热度。该模型能使管理者快速掌握城市舆情的热点问题、以及舆情关注的热点地区等，有助于快速制定响应措施、高效回应群众的关切热点Leveraging natural language processing (NLP) technologies such as place name recognition, keyword extraction, and urban public opinion topic thesaurus, the public opinion analysis model can automatically identify place names, public opinion event types, keywords and other relevant information from urban public opinion texts. By incorporating public opinion similarity recognition technology, it can merge duplicate public opinion events and automatically count the popularity of various public opinion events by region and theme respectively. This model enables managers to quickly grasp the hot issues of urban public opinion and the hot areas focused by public opinion, which helps to rapidly formulate response measures and efficiently address the public's concerns and hotspots.
