Prepared Dataset

The dataset consists of 'friend pairs' from Facebook. Facebook data was collected from survey participants using the Facebook app. For privacy issues, Facebook data has been anonymized by replacing the Facebook-internal IDs with new dummy values.

 

In each line of the file containing this dataset, there are two integer values and these integer values are separated by the horizontal tab character (\t). Here, each integer value represents the IDs of the users. Hence, each line has the format given below, where user1 represents the ID of the first user, user2 represents the ID of the second user and \t is the tab character:         

user1\tuser2

 

Facebook has an undirected relationship format which means that when you become a friend of a user, then this user also becomes your friend as well. For instance, if you see the line given below in the file (integers are separated by a tab), it means that the user with ID 10 is a friend of the user with ID 158, and it also means that the user with ID 158 is a friend of the user with ID 10. In other words, such a line means that the users with IDs 158 and 10 are friends with each other.

10      158

 

You may assume that the file is in correct format for each line and there are no empty lines. However, you cannot make any assumptions on the number of lines and the number of users in the file.
