Modeling the evolution of science in scientific space — •Jan Moritz Joseph1 und Jens Christian Claussen2,3 — 1Institut für Technische Informatik, Universität zu Lübeck, Germany — 2Computational Systems Biology Lab, Research II, Jacobs University Bremen, Germany — 3INB, Universität zu Lübeck, Germany
How does the topological space of science emerge? Scientific disciplines form clusters and topical sub-clusters, overlap through interdisciplinary research, and dynamically emerge and grow over time.
Inspired by the concept of mapping scientific topics to a
scientific space [1], we introduce a dynamical process of authors collaborating and publishing papers [2].
The model fosters novelty and multidisciplinary of new papers, as well as a retirement mechanism which prevents large groups to dominate topics forever. We demonstrate that our model can generate a nontrivial topological structure comparable to [1]. We quantifiy the time-evolution of the spatial structure and discuss the influence of inhomogeneity. Exploring further properties of the dynamics, we examine special and structural characteristics by measuring the fractal dimension. Furthermore, we compare the topology with real data given by the UCSD Map of Science [3].
