Hierarchical clustering of networks
Hierarchical clustering is one method for finding community structures in a network. The technique arranges the network into a hierarchy of groups according to a specified weight function. The data can then be represented in a tree structure known as a dendrogram. Hierarchical clustering can either be agglomerative or divisive depending on whether one proceeds through the algorithm by adding links to or removing links from the network, respectively. One divisive technique is the Girvan–Newman algorithm.
==Algorithm==


In the hierarchical clustering algorithm, a weight W_ is first assigned to each pair of vertices (i,j) in the network. The weight, which can vary depending on implementation (see section below), is intended to indicate how closely related the vertices are. Then, starting with all the nodes in the network disconnected, begin pairing nodes in order of decreasing weight between the pairs (in the divisive case, start from the original network and remove links in order of decreasing weight). As links are added, connected subsets begin to form. These represent the network's community structures.
The components at each iterative step are always a subset of other structures. Hence, the subsets can be represented using a tree diagram, or dendrogram. Horizontal slices of the tree at a given level indicate the communities that exist above and below a value of the weight.
