The third speaker in this Social Media and Society session is Alexia Maddox, whose interest is in the study of online discussions of illicit drug use. Illicit drugs are a stigmatised topic, which has pushed discussion into more permissive spaces such as social media. In Australia, there has been a renewed push to legalise medicinal marijuana, which has increased the volume of discussions about the drug, and this provides the current context for this study.

The project, then, aims to explore the dynamics of the discussion about marijuana on Twitter in Australia, and especially also to identify the key actors …

The next speaker at Social Media and Society is Christopher Mascaro, whose interest is in 'big data' on political communication online. Political discourse studies have traditionally been restrained by geographic and social access, and 'big data' from online activities can overcome some of these barriers; it also introduces some new limitations that must be considered, however.

Christopher's focus is on the 2012 U.S. Presidential Election: how do networks form around the political issues being discussed on Twitter during the campaign? The dataset was generated using TwitterZombie running on Amazon Web Services, tracking an extensible range of hashtags, user handles, and …

It's the second day of Social Media and Society in London, and after a day of workshops we're now starting the conference proper with a keynote by Susan Halford. She begins by pointing out the significant impact of social media on a wide range of areas of public and everyday life. We're constantly presented with the digital traces of social media – with social media data at an unprecedented scale, telling us something about what people do with social media in their everyday lives. This is an unexpected gift, but is also causing significant concern and scepticism.

What is the …

Next in this Web Science 2016 session is Yelena Mejova, whose work examines how privacy is being discussed on social media in Qatar. Privacy has a number of definitions: the right to be left alone, right to intimacy, etc. But privacy is also defined differently in different regions of the world; the dominant western definitions of privacy may not align with definitions that are prevalent elsewhere, such as for example in the Gulf region.

Culture in the Gulf region is relationship-based and collectivist, and loyalty and honour are exceptionally important values. This is also a rapidly developing region, with substantial …

Next up at Web Science 2016 is Yelena Mejova, who presents a paper on the new 'quote retweet' feature that Twitter introduced in April 2015. This form of retweeting includes the retweeted tweet as a URL in the retweet, and can be used for somewhat different purposes from other forms of retweeting: while button retweets may imply an endorsement of the original message, the substantial space for including the retweeter's views in a quote retweet might be used for more critical engagement with the quoted material, for instance.

This study builds on the dataset of 192 US political accounts maintained …

Next up at Web Science 2016 is Claudia Orellana-Rodriguez, whose interest is in how journalists spread the news on Twitter. Journalists now regularly engage on social media platforms, but there still is only a very limited understanding of how platforms like Twitter can be used most effectively.

Optimal activities and user engagement may also differ considerably across different news categories: different types of news will have different audiences, and audience members may engage very differently with such news; this may also be affected by the time of day or week.

This project focussed on 200 Irish journalists and captured …

Next up at Web Science 2016 is Walid Magdy, whose focus is on social media commentary following the terrorist attacks in Paris in late 2016. Immediately after the attacks, sympathy with Paris was expressed on Twitter – but as the attacks were linked with Islamist terrorists, anti-Muslim messages also began to appear.

Walid's team tracked relevant keywords and hashtags on Twitter after the attacks, and noted that more than one tenth of all messages discussed Islam in some form; of these, some 336,000 tweets were closely engaged with the question of Islam in Europe. The majority of these tended to …

The next session at Web Science 2016 is on information dissemination and engagement. It begins with a paper by Miriam Fernandez, whose focus is on promoting behavioural changes to combat climate change. Over the past years, there have been multiple social media campaigns that promote more environmentally responsible behaviours; what can these campaigns learn from theories of behaviour change, and how can these theories be translated into computational methods?

The focus here is on Earth Hour 15, and on the COP21 summit in Paris in 2015. The project draws on the 5 Doors Theory, which describes five stages of behavioural …

And the final paper in this Web Science 2016 session is by Katrin Weller and me. Below are our slides and abstract, and a link to the full paper:

Twitter as a First Draft of the Present – and the Challenges of Preserving It for the Future from Axel Bruns

This paper provides a framework for understanding Twitter as a historical source. We address digital humanities scholars to enable the transfer of concepts from traditional source criticism to new media formats, and to encourage the preservation of Twitter as a cultural artefact. Twitter has established itself as a key social …
