Clustering a graph

Webpartition cuts the original graph into two bipartite graphs. Vertex sets of each new sub-graph form a cluster pair. Thus, a bi-partition co-clusters vertices into two cluster pairs. Clusters of the same pair preserve all features of the original graph except by losing the connections with other cluster pairs. One way to measure the similarity ... In graph theory, a clustering coefficient is a measure of the degree to which nodes in a graph tend to cluster together. Evidence suggests that in most real-world networks, and in particular social networks, nodes tend to create tightly knit groups characterised by a relatively high density of ties; this likelihood … See more The local clustering coefficient of a vertex (node) in a graph quantifies how close its neighbours are to being a clique (complete graph). Duncan J. Watts and Steven Strogatz introduced the measure in 1998 to determine whether … See more For a random tree-like network without degree-degree correlation, it can be shown that such network can have a giant component, and the percolation threshold (transmission probability) is given by $${\displaystyle p_{c}={\frac {1}{g_{1}'(1)}}}$$, … See more The global clustering coefficient is based on triplets of nodes. A triplet is three nodes that are connected by either two (open triplet) or three (closed triplet) undirected ties. A triangle graph therefore includes three closed triplets, one centered on each of the nodes ( See more • Directed graph • Graph theory • Network theory See more • Media related to Clustering coefficient at Wikimedia Commons See more
