email-Eu-core temporal network

Dataset information

The network was generated using email data from a large European research institution. We have anonymized information about all incoming and outgoing email between members of the research institution. The e-mails only represent communication between institution members (the core), and the dataset does not contain incoming messages from or outgoing messages to the rest of the world. A directed edge (u, v, t) means that person u sent an e-mail to person v at time t. A separate edge is created for each recipient of the e-mail. We also have four sub-networks corresponding to the communication between members of four different departments at the institution. Node IDs in the sub-networks do not correspond to the same node ID in the entire network.
