Political blogosphere Feb. 2005. Data compiled by Lada Adamic and Natalie Glance

Vertex "membership" and "color" attributes indicate political leaning according to:

1 : "blue" (left or liberal)

2 : "red" (right or conservative)

Data on political leaning comes from blog directories as indicated. Some blogs were labeled manually, based on incoming and outgoing links and posts around the time of the 2004 presidential election. Directory-derived labels are prone to error; manual labels even more so.

Links between blogs were automatically extracted from a crawl of the front page of the blog.

An undirected igraph graph object with 1222 vertices and 16714 edges.

Graph attributes: ‘name’, ‘Author’, ‘Citation’, ‘URL’, ‘Description’.

Vertex attributes: ‘name’, ‘Source’, ‘membership’, ‘color’, ‘label’.

Edge attributes: NA

This is a modified version of the original network.

From the original graph, the largest connected component was selected, lowering the number of vertices by 268 from 1490 to 1222. All 268 vertices that were removed were isolated in the original graph.

All edges, which were orignally directed, were made undirected.

Finally, the graph was made simple by removing all multiedges and loops. This lowered the number of edges by 11 from 16725 to 16714.
