Evolution of scientific collaboration and discovery on epistemological graphs — •Fariba Karimi¹ and Ammar Nejati² — ¹GESIS institue for computational social science, Cologne, Germany — ²Physics Department, Bonn University

Scientific research is not a task performed by isolated researchers; researchers communicate their ideas, inspire each other and eventually, make a major impact by their scientific discoveries. The new ideas can diffuse in the collaboration network by an adoption mechanism and create a macro-scale impact on the dynamic of science and its paradigm shifts. So far in modelling scientific collaboration, it has been assumed that research topics are objects that scientists pick from a 'pool of ideas', and research collaborations are not related to the inherent structure of the underlying scientific field. Although these assumptions simplify the modelling of scientific collaboration and discovery, they provide no insight on how research topics are connected intrinsically, and to what extend such a connectivity impacts the discoverability of new ideas or the collaboration pattern. In this work, we model the process of scientific discovery and collaboration by assuming that the scientific activity occurs on an underlying (static) epistemological network. Researchers move and discover this network, they establish collaborations with nearby researchers and they can adopt new researchers into the field. Our results show that through this discovery and collaboration 'game', large-scale scientific collaboration patterns emerge, novel scientific fields are established and ultimately, scientific paradigms change in the course of evolution.
