Online Social Networks Research @

WOSN 2009 Data Sets


Data from our WOSN 2009 paper is available from the links below.  Each of the data sets has been anonymized to protect the privacy of the users themselves.  Included is information about the evolving link structure from the networks as well as the communication between users via the wall feature.

Note that we are unable to release any non-anonymized data.

We are aware that properly anonymizing online social network data is very challenging.  Clever schemes have been found to break seemingly well anonymized data sets (e.g., the NetFlix data set).  For the data we make available, we use a "best effort" anonymization.  We do not offer any strong guarantees and we suspect that our anonymization scheme can likely be broken by clever comparisons to other real-world data. We encourage people to help bring problems and fixes to our notice, should they find any.

 

  1. List of links

    These files contain a list of all of the user-to-user links from the Facebook New Orleans networks.  All links are treated as directed, even though they are undirected on Facebook.

    Format:  Gzipped ASCII.  Each line contains two anonymized user identifiers, meaning the second user appeared in the first user's friend list. Finally, the third column is a UNIX timestamp with the time of link establishment (if it could be determined, otherwise it is '\N').

    Data:
    Facebook Links (10.4MB)

  2. List of wall posts

    These files contain a list of all of the wall posts from the Facebook New Orleans networks.

    Format:  Gzipped ASCII.  Each line contains two anonymized user identifiers, meaning the second user posted on the first user's wall. The third column is a UNIX timestamp with the time of the wall post.

    Data:
    Facebook Wall Posts (6.8MB)
