The next speaker at ECREA 2014 is Anssi Männistö, who shifts our focus to the Boston Marathon bomb attack. Mobile social media played an important role in covering this attact: tweets and mobile media were no longer just sources of information, but also tools to very facts and photos and to identify potential suspects, through image recognition software and other facilities.

In Boston, journalists rapidly discovered the first reports and images of the attack from Twitter, and soon came to use them in their own coverage. Such material was then used in official investigations, unofficial hunts for the culprits …

Ok, so I've boycotted the stupidly early 8.30 a.m. paper session at ECREA 2014. My day starts, consequently, with a paper by Helen Kennedy and Rosemary Hill, whose focus is on data visualisation. Data-driven decision-making remains out of reach for those who cannot work with the data directly, and data visualisation may help here.

There are now visualisation agencies such as Periscopic which specialise in data visualisation for social good. The idea here is to mobilise data graphically, to make data useful to a greater audience. Such visualisations include the work of The Guardian's Data Blog, for example …

The final speaker in this session at ECREA 2014 is Christian Pentzold, whose focus is on the discussions around the 2013 affair about the use of protesters' mobile phone data by police in Saxony. There is a discursive social construction of the term 'big data', and different frames of big data have emerged so far.

Transmedia discourse is combining a number of different conceptualisations, and this enables a number of different analytical perspectives and approaches; the speed of the dynamic reconfiguration of these different modes also affects how analysis may proceed.

How can we use slower analytic methods to make …

The next speaker at ECREA 2014 is Frederic Guerrero-Solé, whose focus is on big data on Twitter. Few people know at this point what 'big data' actually means; what discourse about big data are we constructing here? So is big data just a marketing concept? The uses of big data in social networks have largely shaped our understanding of the big data concept; is there therefore a common discourse about big data at least in a social network such as Twitter?

Frederic's project gathered some 400,000 tweets mentioning the term big data or the hashtag #bigdata, and explored …

Our own paper on mapping the Australian Twittersphere was next at ECREA 2014, and I've posted the slides below. Audio to come later, I hope!

Mapping a National Twittersphere: A 'Big Data' Analysis of Australian Twitter User Networks from Axel Bruns

The first ECREA 2014 panel session is one that we have a paper in as well, but we start with Göran Bolin, whose interest is in the construction of audiences through big data-driven research. There is now a large discussion of what constitutes big data, of course, but Göran is bypassing this, focussing instead on the uses of such data to envisage media users.

Much such data are drawn from social media, but it seems that the social is getting further estranged through this; big data means an intensification of statistical and quantitative approaches, and to some extent constitutes a …
