Data Set Information:
4 files are included:
-- it's the file of all the users. This file works as a dictionary of all the users in this data set. It's useful for fast reference. It contains
all the node ids used in the dataset
-- it's the file of all the groups. It contains all the group ids used in the dataset
-- this is the friendship network among the users. The user's friends are represented using edges.
Since the network is symmetric, each edge is represented only once. Here is an example.
This means user with id "1" is friend with user id "2".
-- the user-group membership. In each line, the first entry represents user, and the 2nd entry is the group index.
