Advogato dataset

From TrustLet, a free, collaborative project for collecting and analyzing information about trust metrics.

The Advogato dataset is available at http://www.advogato.org/person/graph.dot as a file in DOT format.

The Trustlet project downloads a daily snapshot of the Advogato dataset file since October 13 2007. The snapshots are made available for other researchers in this directory: http://www.trustlet.org/datasets/advogato/

If you use one of these datasets and you find them useful, please cite my paper Trustlet, Open Research on Trust Metrics (see below), thanks! --PaoloMassa 08:20, 8 April 2010 (UTC)

An almost unique characteristic of the Advogato dataset is that it is weighted: directed edges between nodes are specified on a 3 levels base, Apprentice, Journeyer, and Master, which for instance can be mapped in [0,1] in the following way: Apprentice=0.6, Journeyer=0.8, and Master=1.0

There are other communities who run the same software as Advogato and hence they produce the same graph.dot file and have similar structures: Robots.net, Squeak Foundation, Kaitiaki, persone.softwarelibero.it
