2021, Social NetworksCitation Excerpt :Analysts have long been interested in aspects of variability in network actor centrality measures; here we briefly note some of that work. Bolland (1988) conducted an early study of centrality in simulated networks produced by randomly changing elements of the 0/1 adjacency matrix of an empirical network. Among other analyses, he compared mean correlations between centrality scores in the simulated and original empirical networks under different levels of randomness (up to 20 % of network elements being changed) for different centrality measures.
Comparison of path-based centrality measures in protein-protein interaction networks revealed proteins with phenotypic relevance during adaptation to changing nitrogen environments
2021, Journal of ProteomicsCitation Excerpt :These separated hubs can occur as a result of biological relevance (e.g. multiple self-sufficient protein-protein interaction complexes) or missing data. In addition, because BC is sensitive towards local topology, BC is more affected by missing data or random errors in edge-distribution than degree-based centrality measures [48]. On the other hand, because of its sensitivity, BC is most suited to observe true changes in network connectivity and node importance.
