This is a temporal higher-order network dataset, which here means a sequence of timestamped simplices where each simplex is a set of nodes. In this dataset, nodes are authors and a simplex is a publication marked with the "Geology" tag in the Microsoft Academic Graph. Timestamps are the year of publication. The projected graph is a weighted undirected graph representing how many times each pair of nodes co-appears in a simplex. We restricted to simplices that consist of at most 25 nodes. Some basic statistics of this dataset are:

• number of nodes: 1,256,385
• number of timestamped simplices: 1,590,335
• number of unique simplices: 1,207,390
• number of edges in projected graph: 512,0762

Data restricted to simplices with at most 25 nodes:

• coauth-MAG-Geology.tar.gz (timestamped simplices, node labels, and simplex labels)
• coauth-MAG-Geology-proj-graph.tar.gz (weighted projected graph)

Full data without restriction on simplex size:

• coauth-MAG-Geology-full.tar.gz (timestamped simplices, node labels, and simplex labels)
• coauth-MAG-Geology-full-proj-graph.tar.gz (weighted projected graph)
