Abstract

Gaurd and Security have Since there are many problems that do not match the rapidly changing trend of the times, the overall perception of society was compared and analyzed. In order to provide basic data and provide meaningful implications, data were collected through TEXTOM, and word cloud analysis, LDA topic modeling analysis, emotional analysis, and semantic network analysis were conducted. First, in 'Gaurd', 'Security' has many associations, and 'Gaurd' was suitable to include the meaning of 'Security’. Second, ‘Gaurd’ is a term that allows people to think of related tasks more without being confused than "Security", and it was a term suitable to include the meaning of related tasks comprehensively. Third, it was confirmed that 'Security' clearly had more negative perceptions than 'Gaurd', and 'Gaurd' was found to be a relatively positive term. Fourth, among the terms with strong connection centrality in 'Gaurd', there was 'security' as a term that could replace 'Gaurd' and 'Security', but in 'Security', no term that could imply the meaning of the two terms did not appear. Security, a term that is already widely used in academia and industry and can be replaced without confusion, is expected to be the most suitable replacement for "Gaurd" and "Security" in a large framework and include both meanings.
