Abstract:
[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.
