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

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.
