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 "Geology" tag in the Microsoft Academic Graph. Timestamps are the year of publication. The dataset is restricted to hyperedges that contain at most 25 nodes. Statistics Some basic statistics of this dataset are: Number of nodes: 1,256,385 Number of timestamped hyperedges: 1,590,335 Number of unique hyperedges: 1,207,390 Changelog v0.3: Converted dataset to HIF Source of original data Source: coauth-MAG-Geology dataset References If you use this data, please cite the following papers: Simplicial closure and higher-order link prediction.
