This dataset is associated with the paper “Contagion dynamics of extremist propaganda in social networks” (Information Sciences). PDF

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.
