Network of scientific concepts: empirical analysis and modeling
Vasyl Palchykov, Mariana Krasnytska, Olesya Mryglod +1
Concepts in a certain domain of science are linked via intrinsic connections reflecting the structure of knowledge. To get a qualitative insight and a quantitative description of t…
A mechanism for evolution of the physical concepts network
V. Palchykov, M. Krasnytska, O. Mryglod +1
We suggest an underlying mechanism that governs the growth of a network of concepts, a complex network that reflects the connections between different scientific concepts based on…
Embedding technique and network analysis of scientific innovations emergence in an arXiv-based concept network
Serhii Brodiuk, Vasyl Palchykov, Yurij Holovatch
Novelty is an inherent part of innovations and discoveries. Such processes may be considered as an appearance of new ideas or as an emergence of atypical connections between the ex…
Bipartite graph analysis as an alternative to reveal clusterization in complex systems
Vasyl Palchykov, Yurij Holovatch
We demonstrate how analysis of co-clustering in bipartite networks may be used as a bridge to connect, compare and complement clustering results about community structure in two di…
ScienceWISE: Topic Modeling over Scientific Literature Networks
Andrea Martini, Artem Lutov, Valerio Gemmetto +11
We provide an up-to-date view on the knowledge management system ScienceWISE (SW) and address issues related to the automatic assignment of articles to research topics. So far, SW…
Ground truth? Concept-based communities versus the external classification of physics manuscripts
Vasyl Palchykov, Valerio Gemmetto, Alexey Boyarsky +1
Community detection techniques are widely used to infer hidden structures within interconnected systems. Despite demonstrating high accuracy on benchmarks, they reproduce the exter…
