News and Newsworthy

Paper on temporal graphs at KDD: Our paper titled A Higher-Order Temporal H-Index for Evolving Networks by Lutz Oettershagen, Nils M. Kriege and P. Mutzel has been accepted for publication at the 29th SIGKDD Conference on Knowledge Discovery and Data Mining (KDD 2023). This conference is one of the leading conferences in this area (core rank A*). In our work we generalize the n-th order H-index (a useful centrality measure for static graphs) for temporal networks and define corresponding temporal centrality measures and decompositions. Moreover, we suggest (streaming) algorithms for their efficient computation, and evaluate our methods.

HCM Retreat: We had great presentations and planned the future of our Hausdorff center for Mathematics (Cluster of Excellence at the University of Bonn). If you want to find out more about the HCM, please visit here. [picture: © Volker Lannert]

Best Paper Award at MLG@ECMLPKDD2022: Our paper titled “A Temporal Graphlet Kernel For Classifying Dissemination in Evolving Networks” has won the best paper award at the 18th International Workshop on Mining and Learning with Graphs held in connection with the ECMLPKDD'22. The work is based on the bachelor thesis by Claude Jordan and co-authored by Lutz Oettershagen, Nils Morten Kriege, Claude Jordan, and Petra Mutzel.
