Management and Plan of Undergraduates' Mental Health Based on Keyword Extraction.

Mental health issues are alarmingly on the rise among undergraduates, which have gradually become the focus of social attention. With the emergence of some abnormal events such as more and more undergraduates' suspension, and even suicide due to mental health issues, the social attention to undergraduates' mental health has reached a climax. According to the questionnaire of undergraduates' mental health issues, this paper uses keyword extraction to analyze the management and plan of undergraduates' mental health. Based on the classical TextRank algorithm, this paper proposes an improved TextRank algorithm based on upper approximation rough data-deduction. The experimental results show that the accurate rate, recall rate, and 1 of proposed algorithm have been significantly improved, and the experimental results also demonstrate that the proposed algorithm has good performance in running time and physical memory occupation.
