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

DBLP is a bibliography service from which an undirected scientific collaboration network can be extracted: each vertex represents a scientist and two vertices are connected if they have worked together on an article. This symmetric graph has been obtained in July 2011 from the standard DBLP download.
