DBLP
This is the citation network of DBLP, a database of scientific publications
such as papers and books. Each node in the network is a publication, and each
edge represents a citation of a publication by another publication. In other
words, the directed edge (A → B) denotes that publication A cites publication
B. Publications are allowed to cite themselves, and therefore the network
contains loops. The original dataset contains a small number (<100) of
erroneous duplicate edges, i.e., a paper citing another paper multiple times.
These have been removed from this version of the dataset.
