signed_social_media — Epinions and Slashdot signed social networks (2008-2009)

Description

Directed signed social networks of users of two websites, collected by Leskovec, Huttenlocher and Kleinberg to study positive and negative relationships in online social media. Nodes are users, and a directed edge $(i,j)$ means that user $i$ declared a positive or negative relationship (trust or distrust, friend or foe) towards user $j$.

epinions: the who-trusts-whom network of the consumer review site Epinions.com, where members can declare that they trust (positive edge) or distrust (negative edge) other members. These relationships determine, together with the review ratings, which reviews are shown to the users.
slashdot081106, slashdot090216, slashdot090221: the "Slashdot Zoo" of the technology news site Slashdot.org, in which users tag each other as friends (positive edge) or foes (negative edge), as obtained on November 6 2008, February 16 2009 and February 21 2009. The node numbers are not necessarily consistent across the snapshots. Unsigned versions of the Slashdot Zoo distributed by SNAP are in the entry slashdot_zoo_snap; its network 0811 is from the same date as slashdot081106 and has nearly the same number of nodes, but a different edge set (about 905,000 instead of 517,000 edges).

A third network of the same study, the votes in Wikipedia adminship elections, is available separately (see the elec entry).

The networks have the following properties:

Edges: sign, the sign of the relationship, +1 (trust, friend) or -1 (distrust, foe).
