Abstract： [Purpose/significance] By analyzing the path of thematic evolution of literature resource guarantee system in China, this paper provides references for reconstructing literature resource guarantee system in China. [Method/process] This paper used LDA model to cluster the collected documents. Firstly, it used the time period as the basis of division, drew the co-occurrence network of topic words, and explored the interactions between topics. Then the paper determined the evolution path within each subject by similarity calculation and showed it in the form of visualization by drawing Sankey diagram. [Result/conclusion] The study finds that all the relevant themes of literature resource guarantee system in China have basically appeared around 2000. The topic mainly includes two categories of resources and institutions, which are greatly influenced by computer technology and national policy. The corresponding countermeasures and suggestions are given for these two categories of topics.

Abstract： [Purpose/Significance] Combined with domestic and foreign literature research and the characterization of college students' network information security literacy from the perspective of platform society, this study constructs the evaluation index system of college students' network information security literacy ability and makes empirical analysis, in order to provide references for the scientific evaluation of network information security literacy.[Method/Process] Combined with the previous research, this paper preliminarily constructed the evaluation index system of college students' network information security literacy facing the new environment and carried out network questionnaire investigation. Eight first-level indexes such as "network information security knowledge" and "basic skills for the safe use of the platform" were extracted by the exploratory factor analysis method based on data samples. At the same time, the coefficient of variation method was used to assign weight coefficients to all levels of indicators and the empirical results were analyzed.[Result/Conclusion] The empirical results show that college students perform relatively well in the indicators related to the basic awareness of network information security, while there is much room for improvement at the deep level of multiple cognition, specific knowledge and practical skills. At the same time, the study also finds that the index scores of college students in different grades, different majors and different types of universities do not show significant differences. Based on this, this paper puts forward some countermeasures and suggestions on improving college students' network information security literacy from the perspective of platform society around the three related subjects of "nation-university- individual student".
