Centrality measures in graph theory are used to find the most influential nodes in a graph. Identifying the influential nodes in the truss structures is important to understand the responsible node for design and failure of the structures. Targeting the influential nodes in a structure such as a ...
In subject area: Computer Science Centrality measures refer to the evaluation of how central an individual is positioned within a social network, using tools like graph theory and network analysis. Various measures such as degree centrality, closeness centrality, betweenness centrality, eigenvector centra...
Utilizing centrality measures, an unsupervised learning approach, and concepts rooted in graph theory, the ultimate result of the proposed model comprises a set of influential and crucial proteins. Furthermore, it identifies the shared substructure among these highly essential proteins within the protein...
First, in this paper, a generalized methodology has been introduced for calculating electrical centrality measures based on graph theory. Next, the proposed centrality index has been used for identifying the location for reactive power compensation. Finally, the amount of reactive power required to ...

Network representation has been an incredibly useful concept for understanding the behavior of complex systems in social sciences, biology, neuroscience, and beyond. Network science is mathematically founded on graph theory, where nodal importance is gauged using measures ofcentrality. Notably, recent work...
All measures have been based more or less directly on one or another of them . . . Addressing the notions of degree and betweenness centrality, Freeman says the following: With respect to communication, a point with relatively high degree is somehow “in the thick of things”. We can ...
摘要: Q-measures express the bridging function of nodes in a network subdivided into two groups. An approach to Q-measures in the context of weighted or valued directed networks is proposed. This new approach uses flow centrality as the main concept. Simple examples illustrate the definition....

We exploit graph theory for focusing these large graphs. The method is based on degree centrality, which measures connectedness in a graph. Four categories of clinical concepts related to treatment of disease were identified and presented as a summary of input text. A baseline was created using ...
