A study on the changes of vocational rehabilitation terms through keyword analysis: For media articles written around the time of the COVID-19 pandemic

This study examined the emergence of terms related to 'vocational rehabilitation' by analyzing text mining keywords for media articles related to vocational rehabilitation written before the outbreak of COVID-19 and after the declaration of the end of COVID-19, focusing on the COVID-19 pandemic. As a result of the analysis, first, keywords such as 'disability', 'vocational rehabilitation', 'facility', 'rehabilitation', 'support', 'social', 'occupation', 'center' and 'education' were ranked high. In the process of visualizing the extracted keywords, a change in the central keyword appeared, which was 'rehabilitation' before the COVID-19 outbreak and 'welfare' after 2020. Second, in the N-gram, the combination of keywords related to 'facility' appeared the most in both Bigram and Trigram, especially during the COVID-19 pandemic, content aspects such as education, programs, and services related to vocational rehabilitation for the disabled, and contents such as 'disability-recognition' and 'service-providing' were extracted only before the COVID-19 outbreak, so there were differences.
