Dynamical model of the scientific process: Knowledge generation embedded in the scientific map of science — •Jan Moritz Joseph1 and Jens Christian Claussen2,3 — 1Institut für Technische Informatik, Universität zu Lübeck, Germany — 2Computational Systems Biology, Jacobs University Bremen, Germany — 3INB, Universität zu Lübeck, Germany
We investigate a dynamical growth model [1] of the scientific process comprised by authors writing collaborative papers, where the location of authors and papers are defined in a scientific space [2] in which distances in these ``maps of science'' are defined by similarity between document texts. The goal of our model is to provide a minimal model of the dynamical evolution of the topological structure (beyond network adjacency and geographical author location) of scientific publications. 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 [2,3]. We examine special and structural characteristics of the model in comparison to available data of the UCSD Map of Science [3]. While our model is in some sense minimalistic, it allows to study the influence of global steering parameters on the development of science.
