摘要
近年来利用块模型分析研究期刊互引网络结构引起了部分学者的关注。运用社会网络分析方法及Ucinet分析工具,以SSCI收录的84种图书情报学期刊的互引网络为研究对象,按JCR期刊分类构建期刊子群,创新块模型构建方法。从期刊子群被引情况、块模型和E-I指数三个不同的角度,研究图书情报学期刊子群之间的亲疏关系和依赖程度,进一步探明图书情报学期刊内部知识的流动特性,为学科自身的发展和学科认知提供一定的参考。
Recently, the use of block mode! analysis on Journal inter-citation network structure has attracted some schol- ars＇ attention. The social network analysis methods and analytical tools Ucinetis are employed to study the inter-citation network from 84 kinds of journals in LIS from SSCI. Firstly the Journal sub-groups is generated by its JCR categories and directly translated into sub-blocks in network analysis, then the relationships and dependence among the journals sub- groups and the flowing characteristics of knowledge in LIS journals is comprehensively analyzed from three different as- pects： sub-group cited analysis, block model analysis and E-I index analysis. Finally, conclusion is made concerning its current state and trends, which has a certain reference value for its self-development and cognition.
