Super User temporal network

Dataset information

This is a temporal network of interactions on the stack exchange web site Super User. 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.

Data format

where edges are separated by a new line and

• SRC: id of the source node (a user)
• TGT: id of the target node (a user)
• UNIXTS: Unix timestamp (seconds since the epoch)
