Dataset information                                                        
This is a temporal network representing Wikipedia users editing each       
other's Talk page. A directed edge (u, v, t) means that user u edited user 
v's talk page at time t.

Notes on inclusion into the SuiteSparse Matrix Collection, July 2018:      
The SNAP graph is 0-based, with nodes numbered 0 to n-1 with n=1,140,149.  
It is converted to 1-based in the SuiteSparse Matrix Collection.           
In the SuiteSparse Matrix Collection, the graph A has 3,309,592 entries.   
A(i,j) is the number of times user 1+i editted the talk page of user 1+j,  
at any time (1+ to make the graph 1-based, where i and j refer to node     
numbers in the SNAP data set).  The usernames are held in                  
Problem.aux.usernames, as a char array of size 1,140,149-by-229.           
The kth row of this array (and the kth line of the text file in the        
MatrixMarket and Rutherford-Boeing format) is the username for the kth row 
and column of the Problem.A matrix.  The username file in the SNAP data    
set has both the node number (0 to n-1) and the user name itself; the      
node number is removed in SuiteSparse collection since it is redundant.    
A single user name is blank.  Line 411185 in the SNAP data file            
wiki-talk-temporal-usernames.txt contains just the string "411184 ".  It   
is converted here to "user_411185" (1+ to account for the change from      
0-based numbering in the SNAP data set to 1-based in the SuiteSparse       
Matrix Collection).                                                        
The temporal edges are held in the Problem.aux.temporal_edges array, of    
size 7,833,140-by-3, where each row holds a single (source,target,time)    
edge.  The source and target in this list are 1-based, ranging from 1      
to n=1,140,149.
