In my previous post I mapped the network of anti-jihadist bloggers mentioned in the manifesto of Anders Behring Breivik. This afternoon I stumbled upon a tweet by Martti Tulenheimo requesting something similar on the Finnish blogosphere.
I had actually tried to do something like that a few days ago, but didn’t manage to write the script I wanted. The plan was to use Yahoo’s inbound link API and have it build the network automatically. But I didn’t figure out how to only include links from the main page of a site (as Analyze Banklinks lets you do). So instead I took a more manual approach.
As in the previous post I used Analyze Banklinks to list incoming links. The backlink analysis was done on the following blogs:
These are the blogs listed as “critical voices” on the blog of Jussi Halla-aho (or “the master” as he is refered to on the Homma discussion board) and they serve as a good starting point for this purpose.
I run all of the blogs through Analyze Backlinks to get a network of 133 blogs. I have obviously not read all of these blogs to check if it is correct to label them as immigration critics. The 133 blogs included in this network are merely to sites that link to at least one of the blogs mentioned above.
The results have to be read with some caution. I am not sure how reliable Analyze Backlinks is. Their own disclaimer warns that the results may not be accurate.
Again I used Gephi to draw the network and this is what came out (click to open as pdf):

The size of the sites are determined by the number of inlinks, that is the number of sites that link to the page (not only front page links are counted here). A large number of inlinks indicate that the site is popular. Hence the big dots should be seen as key nodes in the Finnish immigration critic blogosphere.
However, I am not quite sure about the quality of the inlink count that Analyze Backlinks provide. I had a quick look at what numbers that Yahoo’s backlink API throws out and there seems to be a significant discrepancy.
So this analysis is far from perfect, but it’s a start and it gives you a decent idea of what the most important sites are in blogoshere of Finnish immigration critics. If you have thoughts on how the methodology could be improved I would love to hear your comments.

It has been a truly sad weekend with the terrorist attack of Anders Behring Breivik in Oslo, Norway. An extremely important political discussion is now unfolding about the causes of this tragedy. What was for example the role of the expanding anti-jihadist blogosphere?
In his manifesto Breivik keeps referring to five anti-islamic blogs:
All of these bloggers have condemned Breivik and adopted a martyr position after severe criticism from all over the world. But as for example Bjørn Stærk points out the dangerous potential of these bloggers have to be taken seriously.
I wanted to look closer at this network of bloggers. In an initial attempt to map the anti-jihadist I gathered the backlinks (the incoming links) of the five blogs mentioned above (using this site). I only included links from the front page, which means that links from single blog posts were excluded. The result was a list of 749 sites (not only blogs).
I run the list through Gephi and got the following network.

The size of the names are determined by the number of in-links. The sites in the middle are the ones that links to several of the five blogs.
Much more could be done to learn more about this network. One could for example expand the backlink dig to more blogs. Could that process somehow be automated? And could one use some sort of API to get more data on the sites that link to these five blogs? Geo data for example? Don’t hesitate to contact me if you want to contribute.
You’ll find the backlinks I’ve gathered so far on Google Docs.
