Sociomeeting: Duplication-divergence inspired model for growing scientific collaboration networks
Collaboration networks have been extensively analysed, yet most studies focus on large-scale bibliometric patterns rather than the internal processes that drive network formation within individual research centres. In this study, we develop a model inspired by the duplication-divergence mechanism that captures the different processes that typically occur in a research centre (hiring of new people, repetition of collaborations, etc.), and how they shape its collaboration network. Quantities of interest such as the distributions of papers per author and authors per paper, as well as their average number and number of unique authors, are derived analytically and compared with numerical results. Finally, the model parameters are inferred from IFISC data to validate the model's capabilities in a real-world case.
