Math Overflow temporal network

Dataset information

This is a temporal network of interactions on the stack exchange web site Math Overflow. There are three different types of interactions represented by a directed edge (u, v, t):

The graph sx-mathoverflow 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.
