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.

Abstract： [Purpose/significance] Research collaboration is a collaborative research work between different scientific research subjects on specific scientific issues to achieve complementary advantages. International research collaboration is of great significance to promote research performance. Understanding the current research status of the impact of international collaboration on research performance will provide a reference for the future research.[Method/process] This paper analyzes the literature about the impact of international collaboration on research performance from research sample, analysis indicators and analysis method based on the definition of international collaboration and research performance.[Result/conclusion] The analysis results show that the research field is rich in results at present. Domestic and international scholars are mainly from the macro (country or regional, etc.), meso (fields or institutions, teams, etc.) and micro (individuals) -3 levels, using bibliometric, social network analysis and statistical analysis to study on the impact of international collaboration on research performance,with the help of rich international collaboration indicators (simple count indicators and single ratio indictors) and research performance indicators (quantity indicators, quality indictors and indictors like h-index). The research needs to be strengthened including studying at the level of scientists and broadening the analysis based on more research collaboration behaviors; exploring comprehensive indicators of research collaboration and research performance; creating targeted analysis models and controlling some important variables.

Abstract： [Purpose/significance] To solve the inconsistency of disruption index D, and investigate the affecting factors of disruption index in specific applications.[Method/process] This paper pointed out the inconsistency problem of disruption index D, and then proposed Rela_DZ and DZ as alternatives to solve the inconsistency problem of D. Finally, the factors affecting Rela_DZ and DZ were studied from the perspective of citation time window, discipline difference and document types.[Result/conclusion] Rela_DZ avoids the inconsistency problem by solving the non-monotonic problem of D with respect to NR. DZ overcomes the non-strict monotonic problem of D with respect to NF and NB. Taking into account the relative and absolute disruption index will result in more reasonable results. In addition, Rela_DZ and DZ are influenced by citation time window, disciplines and document types. Necessary processing steps are needed when applying the disruption index.

Abstract： [Purpose/significance] The author co-citation analysis is an vital method to explore the domain knowledge structure. In the context of complex development of disciplines, the author’s relevance measure based on the co-citation frequency is quite controversial. The study proposed an improved method for author co-citation analysis based on the similarity of content semantics and the proximity of locations. [Method/process] Based on the introduction of its basic principles, the field of LIS was used as an example to demonstrate the effect of the method, a full-text mining of citations for CNKI Chinese journals was conducted, and the citing sentences and reference positions were then extracted. Combined with pre-trained domain word embedding models, the deep correlation between the co-cited literature and the strength of the connection between the authors were measured. A network analysis and a factor analysis were then used to compare the differences on effects between the method and the traditional method. [Result/conclusion] The results show that the method can more accurately identify the correlation strength between authors, and find more detailed subject knowledge structure, and has a certain scalability and applicability.
