Co-authorships of the ACM Turing and IEEE Von Neumann Awardees

<strong>Co-authorships of the <em>ACM</em> Turing and <em>IEEE</em> Von Neumann Awardees</strong> This map shows the co-authorships of scientists who received: - The <em>ACM</em> A.M. Turing Award - The <em>IEEE</em> John von Neumann Medal - Both of these Nodes were coloured to distinguish Turing (in green) and Von Neumann (in blue) awardees. Red nodes show the recipients of both awards. Node size reflects the "writing efforts": sum 1/n for all papers with n co-authors. Edges in dark grey link two co-authors. Edges in light grey link two awardees who never co-authored a paper but they share at least one co-author (these are opportunities for collaborations). Edge width reflects the strength of collaborations: sum 2 / (n * (n - 1)) for all papers co-authored by two given authors (n co-authors in total). The source data were extracted from the DBLP (http://dblp.uni-trier.de) in February 2015. Peer reviewed conference and journal papers were considered and ArXiv CoRR papers were discarded. For more details about source data processing see (Cabanac et al., 2015). The map was generated with Gephi (http://gephi.github.io). This co-authorship map suggests that the community of CS awardees is a small world with tightly connected scientists. Due to the limited coverage of DBLP (i.e., computer science and frontiers), this map does not show the connections to other disciplines. For a study of the CS awardees as brokers to other disciplines see (Fields, forthcoming). <em>Acknowledgements</em> Thanks go to the DBLP team for maintaining such a valuable service and releasing their data. I am also grateful to my research assistant, Clara Belair, who contributed to this study. <em>References</em> Cabanac, G., Hubert, G., &amp; Milard, B. (2015).
