Overview This is a temporal higher-order network dataset, which here means a sequence of timestamped hyperedges where each hyperedge is a set of nodes. In this dataset, nodes are authors, and a hyperedge is a publication marked with the "History" tag in the Microsoft Academic Graph. Timestamps are the year of publication. We restricted to hyperedges containing at most 25 nodes. Statistics Some basic statistics of this dataset are: number of nodes: 1,014,734 number of timestamped hyperedges: 1,812,511 number of unique simplices: 895,668 Source of original data Source: coauth-MAG-History dataset References If you use this data, please cite the following papers: Simplicial closure and higher-order link prediction.
