email-Eu is an undirected hypergraph built from anonymized email communication within a large European research institution, designed for higher-order network / hypergraph machine learning. As in real email traffic, a single message can involve multiple people; this dataset captures that group interaction by modeling each email as a hyperedge containing the sender and all recipients (reconstructed by grouping (sender, recipient, timestamp)… See the full description on the dataset page:
