Research on scientific knowledge map in field of prevention and monitoring on stampede accidents

In order to solve the problem of unclear development status,development trend and development context in the field of the prevention and monitoring of stampede accidents at home and abroad,the visual software CiteSpace was used to study the knowledge map of 365 related literatures collected from the core collection of Web of Science and CNKI.The results showed that China had the largest number of papers in this field,accounting for 40.6%,followed by the United States with 15.4%,and there were only 25 cooperative connections among 29 countries.Six of the top 20 hot research key words at home and abroad were the same,focusing on the application research of computer vision technology such as convolutional neural network in the field of the prevention and monitoring of stampede accidents.There were some differences in the academic extension scope covered by the field of “prevention and monitoring of stampede accidents” at home and abroad,and the further consensus was needed.Three main development paths of research in this field were obtained.The technical research focusing on deep learning was not only the current research hotspot,but also the research hotspot in the future.
