Instagram Dataset

Source: Public media and user information from (through Instagram API).
Crawling period: Jan 20 – Feb 17, 2014.
Description: The media dataset contains records of the form: the anonymized media ID, the anonymized ID of the user who created the media, the timestamp of media creation, the set of tags assigned to the media, the number of likes and the number of comments it received. The anonymized user network contains asymmetric relations (A follows B); each edge is associated with #likes (by A to media created by B), #comments and the list of comments’ timestamps.


Media dataset: 1.7M media associated to 2K users, with 9M tags, 1200M likes, and 41M comments.
User network: about 45K vertices and 678K edges.


Media dataset: about 51MB (200MB uncompressed).
User network: about 21MB (7MB uncompressed).

Facebook Datasets

During August 2010, I have collected two samples of the Facebook friendship graph, by adopting two techniques:

  1. Breadth First Search (BFS) traversal algorithmIt contains about 7 millions of nodes and 12 millions of edges
  2. Uniform (UNI) sampling approach (rejection sampling)It contains about 7 millions of nodes and 7 millions of edges
