Fig. 2: Assessing similar pairs.
From: Influence of the first-mover advantage on the gender disparities in physics citations
We use bibliographic coupling and hypergeometric statistical tests to select couples of similar papers based on their outgoing citation activities. Then we compare their respective popularity (incoming citations). Each node and each arrow represent a paper and a citation respectively, whereas each dashed arrow represents a potential citation that is missing. The pair of papers being assessed (i and j) are shown in blue and orange, the papers cited by them in yellow, and the papers that cite them in green. The black arrow at the bottom represents a timeline showing the publication times of the papers.
