利用期刊-期刊被引关系的动态性可以映射科学领域的“热点”吗?

Can "Hot Spots" in the Sciences Be Mapped Using the Dynamics of Aggregated Journal-Journal Citation Relations?

Loet Leydesdorff, Wouter de Nooy

摘要:

使用三年的期刊引文报告(2011年,2012年和2013年),使用基于熵统计的方法研究2012年(2011年至2013年)的转变指标。变化可以在期刊水平上使用沿行或列向量的熵产生的边际总和来指示,但也可以通过将转移矩阵导入网络分析和可视化程序(并使用社区发现算法)来指示期刊之间的链接水平。74种期刊被标记为引文不连续变化;但3,114种期刊涉及“热”链接。这些链接大多嵌入一个主要组成部分; 78个集群(包含172份期刊)被标记为网络一级出现的潜在“热点”。另一个发现是,PLoS ONE在数据库中引入了一种新的通信动态。的方法的局限性进行了详细说明,使用一个例子。研究结果表明,在引用动态的发展可以被认为是显着出乎意料的。这可以被用作启发式信息;但是就聚合引用关系的熵统计而言,“热点”的实质意义可以预期因情况而异。

英文摘要:

Using three years of the Journal Citation Reports (2011, 2012, and 2013), indicators of transitions in 2012 (between 2011 and 2013) are studied using methodologies based on entropy statistics. Changes can be indicated at the level of journals using the margin totals of entropy production along the row or column vectors, but also at the level of links among journals by importing the transition matrices into network analysis and visualization programs (and using community-finding algorithms). Seventy-four journals are flagged in terms of discontinuous changes in their citations; but 3,114 journals are involved in "hot" links. Most of these links are embedded in a main component; 78 clusters (containing 172 journals) are flagged as potential "hot spots" emerging at the network level. An additional finding is that PLoS ONE introduced a new communication dynamics into the database. The limitations of the methodology are elaborated using an example. The results of the study indicate where developments in the citation dynamics can be considered as significantly unexpected. This can be used as heuristic information; but what a "hot spot" in terms of the entropy statistics of aggregated citation relations means substantively can be expected to vary from case to case.
