lastfm_aminer — Last.fm social graph
- Description
A snapshot of the social network of Last.fm, a music website and streaming radio service, where users can connect as friends. The network is part of a collection of several online social networks distributed by AMiner (Tsinghua University) for research on social network integration, i.e. on identifying the accounts of the same person across different services (Y. Zhang and J. Tang); judging from the references given with the data, parts of it originate from earlier studies on linking user accounts across services (D. Perito et al., 2011; T. Chen et al., 2012). The crawling procedure is not documented. According to the ICON index, the data were collected in late 2013. Nodes are users, identified by integer IDs, and include all users listed in the source data, 11 of which have no connections. An edge connects two users who are connected in the social network; the type of connection (presumably friendship) is not documented by the source. In the source data each connected pair of users is listed only once, always with the smaller ID first, and the source does not document whether the relationship is directed; the edges are therefore stored as undirected.
The network has the following properties:
- (Node)
name: the user ID in the source data. - (Node)
username: the user name.
