Welcome to the Erdős WebGraph Server!
In this page you can freely, without any registration, download a regularly refreshed webgraph, describing the link structure of a constantly increasing subset of the World Wide Web. We refresh the data every week, and present it at the Download page.
The nodes of the graph are domain names, and two nodes, X and Y, are connected by a directed edge X-->Y if there exists a document (URL) under the domain X that hyperlinks to a document (URL) under the domain Y.
For further information, contact us at info AT web-graph.org.
