Research on the topic discovery and hotspot evolution of the LIS field from the perspective of papers supported by the National Foundation

Abstract

Exploring the fine-grained characteristics of the results of papers funded by national funds is helpful to help researchers more accurately grasp the research hotspots and frontier trends of the discipline to identify the frontier topics of scientific research. Starting from the projects approved by the National Natural Science Foundation of China and the Social Science Foundation of China from 2010 to 2019, this study took the state-funded papers published in the core journals in the field of Library and Information Science from 2010 to 2020 as the research object, constructed a domain dictionary according to the funds and keywords of the papers, and conducted topic discovery for the abstracts of the funded papers based on the LDA model. And explore the evolution trend of common keywords in highly cited papers. The results show that in the field of LIS, the social science fund has more diversified project themes than the natural science fund. Information resource construction and library management research are hot topics in the LIS discipline. With the development of The Times, topics such as information service, network public opinion, and big data gradually become the focus of research.
