The amazon-reviews network is a hypergraph where hyperedges are sets of products reviews on Amazon, as collected by Jianmo Ni, Jiacheng Li, and Julian McAuley (specifically, we use the collection of 5-core datasets). Nodes are labeled by their product categories. Some summary statistics of the dataset are:

• number of nodes: 2,268,231
• number of hyperedges: 4,285,363
• mean / median hyperedge size: 17.1 / 8
• rank of hypergraph (maximum hyperedge size): 9,350
• number of node classes: 29
