Summary:A collection of clustering and decomposition techniques that make
possible the construction of sparse and locality-preserving
representations for arbitrary networks is presented. The representation
method considered is based on breaking the network
G(V,E) into connected regions, or clusters,
thus obtaining a cover for the network, i.e. a collection of clusters
that covers the entire set of vertices V. Several other
graph-theoretic structures that are strongly related to covers are
discussed. These include sparse spanners, tree covers of graphs and the
concepts of regional matchings and diameter-based separators. All of
these structures can be constructed by means of one of the clustering
algorithms given, and each has proved a convenient representation for
handling certain network applications
