Abstract

Crime in modern society is becoming more diverse, violent, intelligent, wide-area, and younger. For this reason, public security and private security should develop together as a mutually complementary relationship, and for this, the public's positive perception and support for private security is very necessary. In order to understand the general public's perception of private security, big data related to private security were collected and analyzed, and related words were identified to examine the relationship between keywords to provide basic data for the development of private security. After collecting 7.556 cases (3.72MB) of data from August 1, 2013 to July 31, 2023 through Textome with the keyword 'private security', network analysis, centrality analysis, and CONCOR analysis were conducted. As a result of the study, "security instructor" appeared as the word with the largest node in network analysis, and "private security theory," "security guard," "license," and "police" appeared. Among the centrality analysis, in the degree centrality analysis, there was a high degree of interest in the test process, subjects, and qualifications to become a security instructor, such as 'security instructor', 'certificate', 'private security theory', 'security guard', and 'security business law'. Closeness centrality analysis showed very different results from connection centrality analysis such as ‘field trip’, ‘went to North Korea’, ‘daycare center’, ‘necessary expenses’, and ‘China’. In the betweenness centrality analysis, it was found that there was a lot of curiosity and interest in private security, such as 'question', 'company', 'necessity', 'police', and 'preparation', and the police's betweenness role was also important. Finally, in the CONCOR analysis, groups clustered with interest in security instructor license, industrial environment, and type of business, Groups clustered into educational institutions and educational environments, Group on the recent "North Korea Incident of U.S. Soldiers in Korea", It was found that words that lacked some relevance were clustered. As a result of lack of understanding or interest in practical private security work in the general public's perception, policies must be prepared to clearly recognize this. After that, if the laws and systems are improved by identifying necessary tasks in addition to the current tasks, development that meets the needs of the people is expected. In addition, promoting and introducing private security-related tasks through great interest in education and educational institutions will help raise public awareness of private security tasks and foster positive awareness. However, in future research, it is necessary to collect more specific data, collect various data as well as specific portal sites, and carry out specific and detailed research so that objective and practical measures can be derived.
