摘要
【目的/意义】党的二十大报告将国家安全置于前所未有的高度。回顾我国国家安全研究进展,并结合党的二十大报告中的国家安全相关论述,展望我国国家安全未来研究,有助于促进新时代我国国家安全研究。【方法/过程】运用CiteSpace与VOSviewer软件,绘制2001-2021年我国国家安全研究的科学知识图谱,并剖析文献的年代分布、作者机构、发文期刊和前沿热点等特征。【结果/结论】近二十年我国国家安全研究整体呈波动增长态势,但研究体系尚不完善,缺乏联系紧密的研究合作网络,研究的纵向深度不足,且前沿方向分散。根据文献回顾和党的二十大报告中的国家安全相关论述,提出应从新时代国家安全学学科建设、国家安全体系和能力现代化研究、国家安全情报学学科建设、国家安全情报体系和能力现代化研究,以及安全六高时代的国家安全新思维、新理论与新方法等方面发力,推动未来我国国家安全研究。【创新/局限】本研究侧重于对我国国家安全研究的宏观分析,可为我国国家安全后续研究提供有益参考,微观层面的具体细化研究有待加强。
【Purpose/significance】Using the content posted by users on social media platforms as data sources,we analyze the evolu⁃tion of public perceptions of vaccine policies in public health emergencies in two dimensions:thematic and emotional,which can pro⁃vide a basis and direction for multiple subjects such as the government and public health departments to carry out accurate vaccine propaganda,popularization services,and public opinion guidance in different life cycle stages【.Method/process】With the perspective of cognitive-emotional-intentional theory,the study integrates SKEP sentiment analysis pre-training model and LDA topic model based on TF-IDF algorithm to calculate the public's sentiment tendency towards vaccine policy at different life cycle stages of public health emergencies,to explore the potential topics and focus of attention of users at different sentiment tendency stages,and then visu⁃alize the public's cognitive evolution process towards vaccine policy.【Result/conclusions】The results of the study showed that the public's emotional tendency trend showed alternating fluctuations of positive and negative emotions,the initial period involved seven topics,the outbreak period involved six topics and generated a large amount of information and emotional expressions,and the spread⁃ing period involved 6 topics,and the process of topic evolution in these three stages reflected both continuity and distinctiveness;the fo⁃cus of public attention throughout the cognitive process mainly included 3 aspects:basic information about vaccines,interpretation and implementation of vaccination policies,and vaccination status【.Innovation/limitation】Only positive and negative sentiments were classi⁃fied in the analysis of public sentiment tendencies,and further fine-grained analysis will be done for sentiment types in future studies.
