| Abstract: | To hackle the research hotspots of urban public safety and its risk more clearly, thus further promote the intensive study on the relevant fields, and improve the management level of urban public safety, the hotspots subjects of urban public safety and its risk were studied by using the news search method. The relevant news about urban public safety and its risk from 2006 to 2016 were obtained by using the crawler software, then the mapping knowledge domain of research hotspots in terms of time, news sources, keywords and application fields was drawn by using the systematic analysis and text analysis. The results showed that the hotspots subjects of urban public safety and its risk mainly include the characteristics analysis on the risk sources of urban public safety, the research on the formation, development, recession, and evolution laws of the risk sources, the education and exercise as well as consciousness cultivation of urban public safety, the exploration of emergency response mechanism, the construction of emergency management system, and the research on the risk monitoring, prediction, early-warning and assessment of urban public safety risk drove by big data. |
