引文和文本分析都被用来研究研究人员,领域和国家之间的思想分布和流动,但由此产生的流动很少是平等的。我们认为,这两种流动的差异反映了科学知识生产中日益增长的全球不平等。我们提供了一个称为“引文透镜”的框架,以确定国家之间的引文应该出现在哪里,但由于其出版的摘要文本中嵌入的内容高度相似,因此没有出现。该框架还确定了在相似性较低的情况下引文过多的地方。我们的数据来自近35年的近2000万篇论文,来自Microsoft Academic Graph的150个领域。我们发现,科学界越来越多地将研究集中在高度活跃的国家,而忽视了边缘国家的工作。这种不平等可能对新思想的发展构成重大挑战。Gomez等人研究了150个领域的国际引文和文本相似性网络,发现包括美国、英国、德国和中国在内的一些国家,尽管研究的主题与其他国家相似,但引用次数越来越多。
Citations and text analysis are both used to study the distribution and flow of ideas between researchers, fields and countries, but the resulting flows are rarely equal. We argue that the differences in these two flows capture a growing global inequality in the production of scientific knowledge. We offer a framework called ‘citational lensing’ to identify where citations should appear between countries but are absent given that what is embedded in their published abstract texts is highly similar. This framework also identifies where citations are overabundant given lower similarity. Our data come from nearly 20 million papers across nearly 35 years and 150 fields from the Microsoft Academic Graph. We find that scientific communities increasingly centre research from highly active countries while overlooking work from peripheral countries. This inequality is likely to pose substantial challenges to the growth of novel ideas. Gomez et al. study international citation and text similarity networks across 150 fields and find that some countries, including the United States, the United Kingdom, Germany and China, increasingly receive more citations despite researching similar topics as others.
