The data are partitioned to europe_data and non_europe_data,
where europe_data contains only posts written in the European subreddits
and non-europe_data contains posts written in other subreddits.
The data of each country are stored in a single CSV file with the columns:
'user', 'subreddit' and 'post'.
The 'user' is the ID of the user, 
the 'subreddit' is the subreddit (Reddit forum) in which the text was posted,  
the 'post' is a full comment or submission of the user.

The posts are tokenized and cleaned of single non-alphabetic characters. 
Non-English posts were removed.
 
The files are sorted by user.
