Select a network data set from the Icon index. The selected network should have at least 1000 labeled nodes and, to prevent duplication, send a reservation to my e-mail. If the selected network is not in Pajek's format you need first to convert it.
For the selected network, using Pajek:
determine basic network characteristics (directed/undirected; weights?; number of nodes, number of links, number of components; largest degree, diameter, acyclic?, …).
draw the degree (in directed also indegree and outdegree) distribution. List 20 nodes of largest degree.
determine the most important nodes.
determine some interesting subnetworks of your network and draw them. Interpret the results.
Write a report.
