NC  Network CentralityDefinition
The centrality measure, named as NC, calculate a node’s
importance based on the number of edges it connects and
the edges’ clustering coefficients. For a node u, its NC(u)
is defined as the sum of edge clustering coefficients of all
edges directly connected with node u:
where N_{u} denotes the set of all neighbors of node u.
Obviously, NC(u) will be larger if node u has higher degree.
NC considers both the centrality of a node and the relationship between it and its neighbors. Edge Clustering Coefficient The edge clustering coefficient of E_{u,v} can be defined as: where z_{u,v} denotes the number of triangles that include the edge actually in the network, d_{u} and d_{v} are degrees of node u and node v, respectively. Then, the meaning of min(d_{u}1, d_{v}1) is the number of triangles in which the edge E_{u,v} may possibly participate at most. References
