If you publish results based on this graph, please quote the references suggested in the dataset page.

One of the most popular undirected social graphs: the graph of movie actors. Vertices are actors, and two actors are joined by an edge whenever they appeared in a movie together.

This graph is the successor to hollywood-2009 and hollywood-2011. We renamed the series because the graphs contains people outside of Hollywood; moreover, the new name makes the original data source clearer.

The graph is built starting from the IMDB datasets and it is thus subjected to their terms and conditions for redistribution. It contains people whose participation is characterized as “actor”, “actress” or “self”.
