国内外公共政策文本分析中主题模型应用研究进展

Application of Topic Models in the Analysis of Public Policy:A Review of the Research Status in Domestic and Foreign

[目的/意义]梳理主题模型在公共政策文本中的国内外应用现状有助于学习已有研究成果,为未来发展提供理论与实践支持。[方法/过程]采用文献计量分析法从时间趋势、机构分布、期刊分布等角度进行量化分析,详细归纳阐述应用现状;其次,通过关键词共现识别国内外主要研究方向并展开对比分析,总结主题模型应用在公共政策文本中存在的问题并提出未来展望。[结果/结论]公共政策文本分析中主题模型的应用整体呈增长态势,前景广阔。国内外研究起步时间相当,但国内研究在研究范围、研究深度、合作方式、研究方法等方面均需提升。此外,未来发展存在主题模型自身方法适用性问题和研究内容粒度问题,需进一步结合公共政策文本特征改进主题模型并细化研究力度。

[Purpose/significance]This paper comprehensively summarizes the application of topic models in public policy texts,which helps researchers learn from existing research results and provides theoretical and practical support for future development.[Method/process]This paper used bibliometric analysis to study from the perspectives of time trend,organization distribution,periodical distribution,etc.,and summarized the application status in detail.Secondly,the LDA topic model was used to identify the main international and domestic research directions and conducted a comparative analysis.Finally,this paper summarized the problems in the application and proposed future prospects.[Result/conclusion]The application of topic models in the analysis of public policy texts is on the rise overall and has broad prospects.The starting time of domestic and foreign research is equivalent,but domestic research needs to be improved in terms of research scope,research depth,cooperation methods,and research methods.In addition,in the future development,there are problems with the applicability of the topic model’s own methods and the granularity of research content.It is necessary to further combine the characteristics of public policy texts to improve the topic model and refine research efforts.
