The final session at Social Media & Society 2018 starts with Supraja Gurajala, whose interest is in using Twitter data for responding to air quality issues. Air quality is a major health issue in population and industrial centres around the world, and metrics like the Air Quality Index (AQI) and Particulate Matter index (PM) are key to its assessment.

Air quality monitoring stations exist around the world, but are unevenly distributed. How might the gaps in monitoring be addressed by increasing the number of monitoring stations, given the costs involved in setup and maintenance, then? One option may be to …

I am the final speaker in this Social Media & Society 2018 session, presenting a paper co-authored with Christian Nuernbergk and Aljosha Karim Schapals, my colleagues in the Journalism beyond the Crisis ARC Discovery project. Here are our slides:

The third speaker in this Social Media & Society 2018 session is Johan Farkas, whose focus is on the activities of the Internet Research Agency (IRA) in St. Petersburg, described as the Russian ‘troll factory’ and indicted for its involvement in Russian interference with the 2016 U.S. presidential election.

There are three forms of propaganda that have been identified in past literature: ‘white’ propaganda has a known source; ‘grey’ propaganda has an obfuscated source; and ‘black’ propaganda claims to be from a legitimate source but isn’t. Is this a useful classification in this context? Do the processes of propaganda dissemination …

The next presenter in this Social Media & Society 2018 session is Oluwaseun Ajao, who shifts our focus to the question of ‘fake news’ on Twitter. Why is such content circulated on the platform? In part this is because these stories often generate more impact than ‘real’ news stories: this might result in significant shifts in political opinion, financial gains, or other outcomes that are desirable to the operators behind such initiatives.

The present study explores whether the veracity of a set of tweets might be able to be ascertained through automated content analysis. Are there semantic of linguistic …

The first paper session on this last day of Social Media & Society 2018 is Michaël Opgenhaffen, whose interest is in gatekeeping on social media. Gatekeeping is one of the fundamental processes in the news industry: editors and journalists choose what stories end up in the final newspaper, news bulletin, or news Website. But selection processes might now diverge across print and online news publications, and the arrival of social media as a medium for the news further complicates this picture.

On social media, audiences receive deep links to news stories on news Websites; they increasingly bypass the homepage of …

The final speaker in this Social Media & Society 2018 session is Andra Siibak, whose interest is in opinion polarisation on social media and the question of whether these constitute ‘echo chambers’ or ‘filter bubbles’. Individual abilities and digital literacies might affect the extent to which users find themselves in such environments, or are aware of them. Andra examined this in the context of an anti-immigration Facebook community in Estonia.

Estonians are particularly strong Internet (and social media) users; this is especially pronounced for younger Estonians. When the European refugee crisis emerged, this manifested in the rapid creation of various …

The third speaker in this Social Media & Society 2018 session is Lea Stahel, who begins with the story of two Muslim schoolkids in a Swiss school, who refused to shake the hand of their female teacher for cultural reasons. This was settled quickly within the school itself, but was raised again out of context by online media coverage some three months after the event, demonstrating how non-mediated and mediated contexts can diverge in the digital age.

There is a perception of legitimacy at the macro-level that influences particular publics’ judgments and actions, and that is affected in turn by …

The next paper in this Social Media and Society 2018 session is by Michael Bossetta, Chris Zimmermann, and Anamaria Dutceac Segesten, whose interest is in patterns in post-Brexit Facebook discussions. In particular, what is the role of emotions in these discussions, and what are their implications? The project gathered data using the Vox Populi data collection, enhanced with other data.

The analysis employed SentiStrength and other sentiment detection algorithms to assess the sentiment, emotionality, arousal, core emotions, and fine-grained feelings in Facebook posts from three major Facebook pages related to the Brexit referendum; most of the discussion took place here …

The final session at Social Media & Society 2018 today is one I’m moderating, and starts with a paper by Ivan Kalmar, Nicholas Worby who explores the connections between Islamophobia and antisemitism in extremist online communication. Islamophobic politicians go to great lengths to claim that they are not antisemitic, in order not to be painted as fascists, yet give enough hints to their followers to still be seen as anti-Jewish.

One of the common targets in this complicated manoeuvre is George Soros, the Hungarian-Jewish billionaire who is generally accused of funding liberal civil society institutions and has been attacked by …

The next speaker at Social Media & Society 2018 is Aske Kammer. He begins by noting that there is a resource exchange between media organisations and third party platforms like Facebook and Twitter. By embedding social media sharing tools or topical advertisements on their own pages, media organisations provide a window for third-party data capture in exchange for the platforms’ services.

For the user, this manifests in multiple server calls as they access the media organisation’s content; in addition to the media organisation, their devices also access various content elements from a range of other platforms. This is not …
