Visualization Analysis of Knowledge Map of the Research Hotspots and Thematic Changes of Data Literacy based on CiteSpace

Based on the visual analysis of CiteSpace knowledge map, this paper presents the research hotspots and thematic changes of data literacy, reveals the evolutionary path of research literature in the field of data literacy, and provides reference for researchers to carry out theoretical research and practical exploration. 206 data literacy documents from CNKI database were analyzed using key word co-occurrence network and cluster analysis to generate knowledge maps of research authors, research institutions, research hotspots and research time trends in the field of data literacy. This paper focused on five automatic clustering of key word co-occurrence networks, such as information literacy, education big data, scientific data literacy, data literacy education, scientific data. The results showed that data literacy research was driven by national policies, and the overall research level needed to be improved. The library was the main position of data literacy education, and the content of data literacy research was mainly foreign education cases, and the research methods were mainly theoretical research, while the empirical research was in sufficient.
