In this second part, we'll follow on from our discussion of key themes in The Other Cheek, Larvatus Prodeo, and Club Troppo by looking at the concept maps which Leximancer produces. But first, a recap of the background for this study: I've already posted about our work in developing a new methodology for mapping link and concept networks in the Australian blogosphere. For a first test run of this project, we archived posts in some 300-400 Australian political blogs between the start of November 2007 (the last month of the federal election campaign) and the end of January 2008. We distinguish between different functional components of blogs and blog pages, and what I'm focussing on here are the blog posts themselves, which are of course the major discursive element of any blog - as part of our approach, we've separated these posts from all other content on the blog (headers, footers, blogrolls, sidebars, comments sections, etc.).
What I've done here in the first place is to run the concept mapping software Leximancer over the content gathered from a selection of key Australian blogs. In the first part of this post, I simply listed the key terms for each blog in order of frequency (giving a quick indication of what they're frequently talking about), which produced some notable differences between the three blogs. My reading of this is that Club Troppo focusses much more strongly on policy analysis over political wonkery and insider gossip; for The Other Cheek, the balance is reversed, while Larvatus Prodeo sits somewhere in the middle.
In this second part, I'll map these blogs' key terms in relation to one another - terms which frequently co-occur in close proximity to one another in the text are located closer to one another on the map than terms which don't, in other words. The resulting maps provide further support to the observation that the blogs have different points of focus in their day-to-day coverage of politics - and by plotting all frequently-used terms on the map, the exact nature of these topical clusters becomes a little clearer, too.
