NETWORK OF SCIENTIFIC CONCEPTS: EMPIRICAL ANALYSIS AND MODELING

Concepts in a certain domain of science are linked via intrinsic connections reflecting the structure knowledge. To get qualitative insight and quantitative description this structure, we perform empirical analysis modeling network scientific concepts physics. end, use collection manuscripts submitted to e-print repository arXiv vocabulary collected ScienceWISE.info platform construct based on their co-occurrences publications. The resulting complex possesses number specific features (high node density, dissortativity, structural correlations, skewed degree distribution) that cannot be understood as result simple growth by several commonly used models. We show model simultaneous account two factors, blocks preferential selection, gives an explanation empirically observed properties network.
