The network data (DOWNLOAD) are available to anyone who wants to use them for non-commercial purposes.
Description of the data
The data are in a gzipped ascii file with the following format. Each line corresponds to one link (i.e., e-mail) from the first to the second address. As described in detail in the above paper, e-mail addresses correspond to internal ("s") and external ("x") nodes. An exemplary line of the file is explained below. Users and domains were made anonymous by the service provider.
Example
| month | day | time | internal/
external | user
(source) | @ | domain
(source) | internal/
external | user
(destination) | @ | domain
