Compute degree centrality, Pagerank and HubAuthorities scores for the flickr network.
Data contains sparse matrix A and list of user names. This is a “denser” part of the Flickr photo sharing site friendship graph from 2006. Edge direction corresponds to friendship requests (following). Some of the links are reciprocal,others not.
Provide top 50 names in each ranking, compare results
You can load .mat files with the following commands:
import scipy.io
data = scipy.io.loadmat('filename.mat')
Here are the Facebook friendship graphs from several US universities from 2005 (one year after fb launch).
Data contains a A matrix (sparse) and a "local_info" variable, one row per node: a student/faculty status flag, gender, major, second major/minor (if applicable), dorm/house, year, and high school. Missing data is coded 0.
Compute node degree assortativity (mixining by node degree) and assortativity coefficient (modularity) for gender, major, dormitory, year, high school for all universities and compare the results.
