Communication Volumes in Social Relationships in Online Communication Systems

These files contain the sending messages behavior.

The columns of the files show row numbers, message sender's user id (uid1), message recipient's user id (uid2), the number of characters (cv), and date index (i).

Each row shows each day data of the combination of uid1 and uid2.

uid1 was determined based on the different rules of uid2.
