Brisbane.
I'm the first speaker of the next session of ANZCA 2009, presenting some baseline data from our first test run of our blog mapping methodology during the Australian federal election in November 2007. The Powerpoint is below (with audio to follow soonish also online now), and the full paper is online as well. Links to more information are in the final slide of the Powerpoint.

Athens.
After the rather unruly cultural panel, WebSci '09 has now moved on to the next keynote, by Noshir Contractor. His theme is the application of Web science to social networks, and he begins by noting some of the experimental mobile tools now available for social networking. The Web in general enables us to communicate and collaborate with any one at any time, but what is necessary are tools that enable us to identify who it is that we should be or want to be collaborating with. This is where social network analysis and Web science comes in.

Athens.
The second and last day of WebSci '09 starts with a session on social networking, although the first paper in this session, by Yorgos Amanatidis, has the somewhat technical title "Kernels for Complex Networks" - we'll see what that's all about... Visual network graph models, apparently, for graphs which represent relational data in an abstract way. Such graophs can be used in the analysis, simulation, and prediction of network topologies, focussing especially on aspects like scaling, clustering, and node centrality.

What can be observed in real networks is the degree distribution: as the Web grows, the average degree is constant, but there is huge variance and no concentration around the average; indeed, we see the small world phenomenon which produces networks with small diameter and strong clustering tendencies (the friend of my friend is likely also to be my friend). Kleinberg, for example, modelled the fact that in small world networks there are not only short paths between nodes, but that these nodes can find such paths effectively using local information.

Athens.
Finally for this first day at WebSci '09, we move to the poster session, which includes our poster on the Australian political blogosphere mapping project; the A1 poster itself is available here, and there's also a brief article to provide further background detail. From the post slideshow that's playing at the moment, there's quite a bit of really interesting stuff here - and all of the posters are also available online.

Athens.
The first full day here at WebSci '09 begins with a keynote by NIgel Shadbolt, founding director of the Web Science Research Initiative (WSRI). As we're in Athens, he begins by taking the historical approach: he notes that another way to describe Web science is as 'philosophical engineering', which links back ultimately to the founding fathers of philosophy, including Socrates, Plato, and Aristotle. Their pure philosophical speculation, indeed, formed the basis not only for modern philosophy, but also for modern science.

Time to catch up with a few publications - my recent work is featured in a number of new collections:

Mobile Technologies: From Telecommunications to Media, edited by Gerard Goggin and Larissa Hjorth, collects some of the best papers from the Mobile Media 2007 conference (which I blogged about at the time) in Sydney. Looks like a fabulous collection, and I'm delighted that an article by former QUT Visiting Scholar Liu Cheng and me about SMS news in China has been included. We're looking especially at the experience at Yunnan Daily Press, where Cheng led the roll-out of SMS news functionality, and we're including some staggering statistics about the growth of Internet and mobile use in China as well (I wonder how they'll be affected by the global financial crisis...).

In just over a week, I'm off to Europe for the first of a number of conference trips this year; as always, I'll try to blog my progress as I go. My first stop is the WebSci '09 conference, where I'm presenting a poster on the background to our blog mapping project (which has already produced papers at the AoIR and ISEA conferences last year, with more to come). Should be interesting, even if it's a lot more (computer and social) science-y than what I'd usually attend. And, they've got Tim Berners-Lee as a keynote speaker - no doubt in honour of yet another anniversary, and one which I didn't even mention in my post the other day: yes, the Web, too, first happened 20 years ago (or at least that's when Sir Tim first proposed his hypertext transfer protocol)!.

Copenhagen.
We're starting the last day of this very enjoyable AoIR 2008 conference already. This one is going to busy for me, as three of my papers are scheduled for today - two of them, in fact, in competing sessions (but luckily my colleagues Lars Kirchhoff and Thomas Nicolai, who are the lead authors, are able to present one of them). This morning, we're starting with a session on the online dimensions of national elections across a number of countries.

The first presenter is Yeon-Ok Lee, whose focus is on last December's presidential election in South Korea. The previous election to this, of course, was won by a small margin by the liberal underdog Rooh Moo-Hyun, due in good part to the activism of Korea's Netizens and to coverage by citizen journalism site OhmyNews. This made the 2007 election a particularly interesting case for further research.
