If you publish results based on this graph, please quote the references suggested in the dataset page.
This graph is a large snapshot of the web taken in 2015 by BUbiNG starting from the site http://europa.eu/ without any domain restriction. The maximum number of pages per host was set to 100 to find a large number of hosts (gsh stands for “general shallow”).
You can also get the graph of hosts and top private domains (explained here).
