Table 2 CiteSpace analysis terms.
| Co-authors | Two or more authors who co-create an article and are jointly responsible for the knowledge content of the article |
| Co-cited reference | Two published articles were co-cited by later articles |
| Co-cited authors | The articles of the 2 authors were cited by the third author. There is a co-cited relationship between the 2 authors. If the co-cited frequency of the 2 authors is higher, the academic relationship between the 2 authors is close |
| Co-occurring keywords cluster | A graphical representation of the number of keywords that appear |
| Modularity(the Q score) | When the Q score is greater than 0.3, it is considered that the divided cluster structure is significant |
| Silhouette (the S score) | It’s useful in estimating the uncertainty involved in identifying the nature of a cluster. when the S score exceed 0.7, the cluster is considered to be highly credible |
| Centrality | A commonly used centrality metric is the betweenness centrality, which measures the percentage of the number of shortest paths in a network to which a given node belongs. Nodes with high betweenness centrality tend to be found in paths connecting different clusters and are considered key hubs |
| Burst | Burst detection determines whether a given frequency function has statistically significant fluctuations during a short time interval within the overall time period |
| Sigma | It is calculated as ( + 1), and the higher these values, the greater the influence potential of the authors or articles |
| Top N | The top N items (countries, institutions, authors, articles, keywords) in each time slice were cited or occurred most frequently |
| Size of nodes (N) | It is related to the number of publications (countries, institutions, and authors) and co-cited times (authors, articles) |
| Purple outer rings | The importance of nodes in terms of betweenness centrality (≥0.1), and the thickness of the ring is proportional to the value of the betweenness centrality |
| Red outer rings | The thickness of the red outer ring of the node represents the burst strength |
| Number and thickness of links (E) | The degree of cooperation between the 2 nodes (countries, institutions, and authors) and the correlation between co-cited references |
| Color of links | The color of the link indicates the time of the first connection |
