dblp_simplices — DBLP coauthor simplices (2017)

Description

A temporal bipartite network of co-authorship among computer scientists, constructed by A. R. Benson and collaborators from the DBLP computer science bibliography, as of 3 September 2017. Each publication is a simplex formed by the set of its authors, and is timestamped with the year of publication. The networks are named <dataset>-<representation>, where the dataset is either full, with all publications, or max-25, restricted to publications with at most 25 authors, and the representation is one of:

bip: a bipartite network of publications and authors, in which each publication is connected to each of its authors. Publication nodes come first, followed by the author nodes.
proj: the one-mode projection onto the authors, where each publication adds an edge between every pair of its authors, so that pairs of authors who wrote several papers together are connected by multiple parallel edges, one for each paper. Publications with a single author do not contribute edges.

The networks have the following properties:

Nodes: label, the name of the author (empty for publication nodes); is_simplex (bip only), whether the node is a publication (otherwise an author).
Edges: time, the year of the publication.
