为JCR图书情报学66种来源期刊构建引用矩阵,采用社会网络分析方法分析期刊引用网络的整体结构,包括密度、度数中心度、网络结构对等性。根据度数中心度得到学术情报吸收能力和学术情报提供能力的期刊排名;从期刊引文网络密度可看出,国际图书情报学期刊间的学术情报交流不如国内图书情报学期刊频繁;从网络结构对等性角度将图书情报学期刊分成4个子群,并用块模型和像矩阵从宏观角度审视引文网络的总体结构。
This paper constructs a reference matrix for 66 journals of JCR Library and Information Science. The social network analysis method is used to analyze the overall structure of journal citation network, including the density, the degree of degree center, and the network structure equivalence. According to the citation network density, we can see that the exchange of academic information between international LIS journals is not as good as that of domestic Journals of Library and Information Science. From the network structure equivalence The angle of view divides LIS journals into four subgroups and examines the overall structure of the citation network from a macroscopic perspective using block models and image-like matrices.
