SNAP (Stanford Network Analysis Platform) Large Network Dataset Collection, Jure Leskovec and Anrej Krevl, http://snap.stanford.edu/data, June 2014. email: jure at cs.stanford.edu Super User temporal network https://snap.stanford.edu/data/sx-superuser.html Dataset information This is a temporal network of interactions on the stack exchange web site Super User (http://superuser.com/). There are three different types of interactions represented by a directed edge (u, v, t): user u answered user v's question at time t (in the graph sx-superuser-a2q) user u commented on user v's question at time t (in the graph sx-superuser-c2q) user u commented on user v's answer at time t (in the graph sx-superuser-c2a) The graph sx-superuser contains the union of these graphs. These graphs were constructed from the Stack Exchange Data Dump. Node ID numbers correspond to the 'OwnerUserId' tag in that data dump.

In the SuiteSparse Matrix Collection, the primary matrix, Problem.A, is the overall static graph, with 924,886 edges, of size n-by-n with n=194,085. These edges represent the 1,443,339 temporal edges. A(i,j) is the number of times person u=nodeid(i) interacted with person v=nodeid(j), with a temporal edge (u,v,t), with any kind of interaction. Problem.aux.nodeid is a list of the node id's that appear in the SNAP data set. A2Q = Problem.aux.Q2A is the static sx-superuser-a2q graph. C2Q = Problem.aux.C2Q is the static sx-superuser-c2q graph. C2A = Problem.aux.C2A is the static sx-superuser-c2a graph. These sum together to give the the overall graph. That is, A = A2Q + C2Q + C2A. A2Q(u,v) is the number of times person u answered v's questions. C2Q(u,v) is the number of times person u commented on v's question. C2A(u,v) is the number of times person u commented on v's answer. The temporal edges are held in: Problem.aux.temporal_edges: [1,443,339 x 3] Problem.aux.temporal_edges_a2q: [ 430,033 x 3] Problem.aux.temporal_edges_c2q: [ 479,067 x 3] Problem.aux.temporal_edges_c2a: [ 534,239 x 3] Each row in these matrices is a single temporal edge, (u,v,t). Summing up all entries in A gives 1,443,339 and likewise the sum of entries in the other graphs gives the number of temporal edges they represent. |
