The DBLP computer science bibliography provides a comprehensive list of research papers in computer science. This dataset is a co-authorship network constructed upon the DBLP dataset, where two authors are connected if they publish at least one paper together. Publication venue, e.g, journal or conference, defines an individual ground-truth community; authors who published to a certain journal or conference form a community. Each connected component in a group is regarded as a separate ground-truth community The ground-truth communities which have less than 3 nodes have been removed. The dataset provides also the top 5,000 communities with highest quality and the largest connected component of the network.
