dblp_coauthor — DBLP co-authorships (2017-2026)

Description

Scientific collaborations among authors of publications in the dblp computer science bibliography. The data are from the XML dump of dblp, the computer science bibliography maintained by the University of Trier and Schloss Dagstuhl, which lists publications from journals, conference proceedings, books, theses and the arXiv Computing Research Repository (CoRR). The collection contains one network for each of two monthly releases of the dump: 2017, from the release of 2 May 2017, and 2026-10, from the release of 3 October 2026. Each record of the dump is a publication of one of the types article (journal articles and CoRR preprints), inproceedings (conference papers), proceedings (edited proceedings volumes), book, incollection (book chapters), phdthesis or mastersthesis, and, in the release of 2026, also data (research data and artifacts); the person records (homepages) of the dump are not used. Authors are identified by their dblp name, which dblp disambiguates by hand where it can (homonymous authors are distinguished by a numeric suffix, e.g. "Wei Wang 0001"), but some of which may still refer to several persons. Nodes are authors, and an undirected edge between two authors means that they co-authored a publication; each publication with $k$ authors contributes $k(k-1)/2$ undirected edges, one between each pair of its authors, so that the network is a multigraph, with as many edges between two authors as their joint publications (i.e. it is a projection of the bipartite network of authors and publications). Editors of proceedings volumes are not included, and neither are authors without co-authors.

The network has the following properties:

name: the name of the author.
year (edge): the year of the joint publication (-1 if missing).
n_authors (edge): the number of authors of the joint publication.
