The attention inequality of scientists: A core-periphery structure perspective

Abstract

This study investigates the dynamics of scientific attention within author citation networks, utilizing the Microsoft Academic Graph dataset. Three author citation networks were constructed within the domains of nanoscience, chemical physics, and human-computer interaction. We apply analytical measurements to reveal core-periphery structures, indicating a growing disparity in scientific interactions. Our analysis highlights a concerning trend: while connections among prominent authors are strengthening, interactions among “ordinary” scientists remain relatively weak. This trend is further corroborated by the application of the network percolation method. After removing the prominent authors in the citation networks, multilayered and complex relationships among authors are revealed. We observe a decreasing trend of connection strength among relatively “ordinary” authors. The observed inequality of attention raises significant concerns about neglecting diverse voices within the scientific community. In response to these phenomena, our research emphasizes the importance of cultivating an inclusive scientific environment for early-career and underrepresented scholars, aiming for long-term sustainability in the scientific community.
