Exploring the Emerging Trends of Spatial Epidemiology: A Scientometric Analysis Based on CiteSpace

Abstract

Infectious diseases are common challenges faced by people around the world, which jeopardize public health, as well as human well-being in various aspects of social and economic development. Although much progress has been made in spatial epidemiology, there is still very little scientific understanding of knowledge domain mapping with scientometric analysis. Based on a total of 4,552 literature records collected from the Web of Science Core Collection™, quantitative changes, research frontiers, research hotspots, and collaboration networks were analyzed by CiteSpace. The results show that both total publications and sum of times cited per year exhibit a rapid development trend in recent decades. The USA, England, and France are highly active in the field. The network of documents co-citation analysis is validated with almost same importance of documents, and primary research frontiers are landscape genetics, modeling and spatial analysis, and tropical diseases. The clustering of the keywords co-occurrence analysis network is heterogeneous and highly reliable, and research hotspots are related to phoma stem canker, vector preference, and aerosol chemical component. Scholars in the field of spatial epidemiology are closely connected, and they have been in a stable cooperative network, as well as institutions. Overall, scientometric analysis based on CiteSpace provides a sound tool to better understand the frontiers, hotspots, and emerging trends in the research domain of spatial epidemiology.

Research progress, trends, and updates on pollutants removal by Bi2WO6-based photocatalysts under visible light irradiation

“…The combined illumination and clustering of highly cited journals showed that the centrality of Applied Catalysis B-Environmental (0.38) and Journal of Physical Chemistry C (0.22) were both greater than 0.1, indicating high recognition in the field compared to other journals ( Table 4 ). Meanwhile, the number of citations of journal articles represented the relevance and importance of the academic community, which directly demonstrated the importance degree and literature quality of the article in the field of Bi 2 WO 6 -based photocatalytic nanomaterials [ 52 ]. The top 10 journals with the most cited and produced articles from 2007 to 2021 showed that the top three cited journals were Applied Catalysis B-Environmental (9301), Journal of Physical Chemistry C (4425), and Applied Surface Science (4386).…”

Studies on HIV/AIDS Among Students: Bibliometric Analysis

“…The analysis of keywords can reveal the development process, explore research hotspots, and especially predict the future development trend of a field [ 31 ]. The basic principle of keyword co-occurrence analysis is to calculate the co-occurrence frequency of keywords in different articles and use the co-occurrence frequency to measure the relationship between keywords [ 8 ]. There were 752 nodes and 4484 links in this network.…”

“…It plays an important role in describing keyword co-occurrence and cocited reference networks. CiteSpace can not only predict emerging trends of spatial epidemiology in infectious diseases [ 8 ] but also analyze patterns of relationships between nanosciences, health, and biology [ 9 ].…”
