An analysis of the co-author networks in recent five-year Chinese papers in dermatology and venereology field / 中华医学科研管理杂志

ABSTRACT

Objective Purpose to study the domestic conditions of co-authorship in the field of dermatology and venereology in recent five years.Methods Taking 9 higher impact factor periodicals of the field as samples and using UCINET software to conduct research from following three perspectives,density,degree centrality,betweenness centrality and subgroup analysis.Results The density of co-authoring network is 0.3313.SUN Jian-fang possesses the highest value of degree centrality,and HUANG Chang-zheng's value of betweenness centrality is the highest.Ten 2-plexes are found in 122 core authors.Conclusions The study found that papers in this field have a high co-authored rate.But the lower network density and isolated nodes indicate that the connection between core authors is loose.There are more notable differences between active authors than inactive ones.The consistency of overall network is poor and other authors’ dependence of central authors is weak across the entire network.Meanwhile,authors of this field have not yet formed a subgroup phenomenon.
