A dynamical model of knowledge generation in scientific space — •Moritz Joseph1 and Jens Christian Claussen2,1 — 1INB, Universität zu Lübeck, Germany — 2Computational Systems Biology Lab, Research II, Jacobs University Bremen, Germany
How does the topological space of science emerge? Inspired by the concept of mapping scientific topics to a scientific space [1], we question which topological structure a dynamical process of authors collaborating and publishing papers can generate.
We propose a dynamical process where papers as well as new groups receive topical positions embedded in a, e.g., two-dimensional euclidean space. The precise position of new papers depends on previous topics of the respective authors and is chosen randomly in a surrounding neighborhood including
novelty and interdisciplinarity. Depending on parameters, the spatial structure resembles a simple Gaussian distribution, or
spatial clusters of side-topics are observed.
We quantify the time-evolution of the spatial structure
and discuss the influence of inhomogenities.
