Claim One:
1. A method of network analysis comprising: obtaining data defining interactions between a set of elements; storing the data as network data wherein the network data defines a network comprising a plurality of nodes and a plurality of links between the nodes; generating data defining a plurality of groups of nodes of the stored network data; determining for each of the plurality of groups of nodes one or more values indicative of the extent to which removal of the group of nodes from the network affects the structural integrity of the network; generating further data identifying further groups of nodes; processing the network data to determine for each of the further groups of nodes one or more values indicative of the extent to which removal of the further groups from the network affects the structural integrity of the network, identifying the groups of nodes from the plurality of groups of nodes and the further groups of nodes associated with values above a threshold value; and outputting data identifying groups of target elements identifying groups of elements corresponding to the identified groups of nodes associated with values above a threshold value.
