| With the increasing complexity of social problems,interdisciplinarity is an important driving force and inevitable trend in the development of modern scientific innovation.Unlike the vertical in-depth analysis within a single discipline,interdisciplinary intersection focuses more on horizontal expansion,and the trend of multi-disciplinary breakthroughs and cross-fertilization is increasingly obvious.At the end of 2021,the Office of the Academic Degrees Committee of the State Council decided the latest version of the outline of the discipline catalog,in which the first-level discipline of "Library Information and Archives Management" was changed to "Information Resources Management"."In this context,it is more important for library and information science to be a major subject.In this context,library and information science should continue to promote the cross-fertilization of disciplines in order to enhance the influence of the discipline and broaden its growth space.Based on the perspective of knowledge flow,this paper analyzes the current situation of interdisciplinary intersection of domestic library and information science disciplines from two perspectives of knowledge input and output,using complex network indicators and Leiden community division algorithm,and fine-grained analysis of topics,journals and authors.It is concluded that the interdisciplinary knowledge flow of library and information science is stable,and the knowledge output is gradually strengthened and the interdisciplinary intersection with automation technology,computer technology,economics,and science and scientific research at different granularity behaves differently.The knowledge flow and integration between library and information science and highly interdisciplinary disciplines based on the perspective of knowledge flow are clarified.The evolutionary trends of library intelligence and automation technology,computer technology,economics,and science and scientific research in the past ten years are analyzed by using Map equation algorithm,and the evolutionary trends of interdisciplinary intersection of library intelligence are characterized as knowledge-led,digital intelligence-empowered,and innovation-driven.It reveals the profound influence of digital technology and information on the cross-knowledge flow of library and information science,and also reflects the focus and direction of future research.Finally,this paper puts forward suggestions based on the conclusion of cross-disciplinary research in library and information science in China,such as promoting disciplinary cooperation,improving the knowledge output influence of library and information science,strengthening the construction of journals,promoting interdisciplinary research,building communication channels,promoting cross-border cooperation among scholars,focusing on popular research directions of disciplinary crossover,grasping future trends,breaking through academic barriers,and cultivating interdisciplinary talents,with a view to promoting crossover between library and information science and different disciplines and Promote the growth,integration and sharing of cross-knowledge in library and information science. |
