email_eu — Email network (EU research inst.)
- Description
An email network from a large European research institution, compiled by J. Leskovec, J. Kleinberg and C. Faloutsos from anonymized information on all incoming and outgoing email of the institution over a period of 18 months, from October 2003 to May 2005. Nodes are email addresses, and a directed edge $i \to j$ means that address $i$ sent at least one email to address $j$. Since the data contain only emails sent or received by the institution, communication between addresses outside the institution is not observed. Some addresses sent emails to themselves, resulting in self-loops. Nodes are identified only by anonymous numeric identifiers, and the network has no node or edge properties.
