The next AoIR 2013 paper is by Pieter Verdegem and Evelien D'Heer, who shift our focus to regional elections in Flanders. The role of Twitter in politics has been described from both optimistic and pessimistic perspectives; the Twittersphere has been seen by many to reflect existing social structures. Is there a move from formal and representative politics towards networked politics, though? From broadcasting to convergence logic?

Pieter and Evelien captured all @mentions in the #vk2012 debate, engaging in both content and network analysis. The hashtag was promoted by the public service broadcaster in Flanders, so it provides a useful point …

The next presenter on this AoIR 2013 panel is Christian Christensen, whose interest is in the minority parties in the US presidential election. He examined the tweets of four minority parties, defined as parties which had enough ballot listings across the states to technically be able to win the election: the Libertarians, the Greens, the Constitution Party, and the Justice Party. This, then, is a study of third party politics - and such parties have traditionally adhered to a polarising and populist style of politics.

In combination, the four parties' candidates had some 129,000 Twitter followers, led by the Libertarians …

Well, with our Twitter and Society book officially launched, I'm now in a final AoIR 2013 session on politics and Twitter. First off, Kevin Driscoll is presenting on the role of Twitter in the US presidential election, noting how much "Twitter's opinion" was used as a yardstick for overall public opinion. There is some slippage here: "Twitter" as the Twitter community, "Twitter" as Twitter, Inc., and "Twitter" as a source of opinion data.

Kevin and his colleagues examined the Twitter activity around the three US presidential debates, following the live Twitter streams as the debates happened and dynamically adding more …

I'll be writing much more about this very soon, but for now just a quick note to say that one of the major events at AoIR 2013 was the launch of Twitter and Society, the new collection edited by Katrin Weller, Jean Burgess, Merja Mahrt, Cornelius Puschmann and me which will be published by Peter Lang in the coming days. The book contains more than 30 chapters by a stellar line-up of Internet scholars, and should be listed on Amazon and the Peter Lang site within the next week - I'll post an update then. For a preview of …

Cumulative and Comparative Social Media Analytics for Crisis Communication from Jean Burgess

The third speaker on our AoIR 2013 crisis communication panel is Megan Finn. She begins by noting that the US Geological Survey is now using Twitter data to detect earthquakes - but more generally, there are also limits to the use of Twitter and other social media data, as not all groups in society are equally represented in such data, and in social media as such.

A disaster is traditionally defined as an event, concentrated in time and space, in which society undergoes severe data and essential functions of society are interrupted. But the components of this definition are problematic …
