Social Media

The final speaker in this ECREA 2018 session is Svetlana Bodrunova, whose focus is on polarisation in Twitter-based discussions of inter-ethnic conflicts in the U.S., Germany, and Russia. She also notes that the debate about whether echo chambers and filter bubbles are real is still ongoing, and that attitudes towards political actors have been most researched to date; divergence in such attitudes is often interpreted as polarisation, but this often mistakes the formation of homophilous clusters for actual polarisation. Importantly, too, cluster formation is often non-binary, and instead leads to the development of multiple, overlapping, and dynamic thematic clusters.

The next speaker in this session at ECREA 2018 is Anne-Marie in der Au, who notes evidence that individual selection of media content may foster polarisation; however, there is also suspicion that algorithmic selection may foster such polarisation by building on and reinforcing such selective exposure. But empirical evidence on this is divided; several studies show no algorithmic impact or even demonstrate a negative correlation. What is going on here, and are there other variables that may interfere?

The next speaker in this ECREA 2018 session is Edda Humprecht, whose focus is on polarisation on Facebook. There is evidence of considerable negativity on this platform, and this may affect users’ perceptions of the world around them; in particular, it may increase their perception of societal polarisation. News outlets operating on the platform are now often accepting negative comments because they do not want to be seen to be censoring user comments – yet at the same time they are complaining about the negative aspects of user participation on social media.

The next speaker in this ECREA 2018 session is Jasmin Kadel, who presents a comparative study of polarisation across Switzerland and Germany. Polarisation can be understood along factual (across issues), perceived (misjudgments about polarisation in society), and affective dimensions (appreciation of co-partisan others); the study examined such polarisation amongst adult newspaper readers in both countries.

The first session on this first full day at ECREA 2018 is on polarisation, and starts with Melanie Magin. She begins by highlighting the potential deleterious effects of polarisation on society: societies need a common meeting ground, and this has traditionally been provided by the news media and their agenda-setting function. But the diversification of information sources and channels may contribute to fragmenting this, and the algorithmic selection of content in these channels could aid this fragmentation – yet there is very little empirical evidence for the existence of the echo chambers or filter bubbles this is said to cause.

The final iCS Symposium session continues the bot theme with a presentation by Pascal Jürgens. Pascal begins by outlining our current dilemma: threats of communicative manipulation via social media are rising, yet our access to the platform data we need to understand these activities is declining. But we may be able to address this dilemma by employing new and different methodologies.

It’s the final session of the iCS Symposium before we wrap up, and we start with Yevgeniy Golovchenko and a study of Russian trolls on Twitter and YouTube during the 2016 U.S. presidential election. In particular, this project focusses on the accounts run by the now infamous Russian troll factory, the Internet Research Agency (IRA), that have now been uncovered by a number of mainstream social media platforms.

The final keynote speaker at this iCS Symposium today is the wonderful Katrin Weller, whose focus is on what we do with social media research data: datasets that have been collected by researchers and have already been utilised in scholarly analysis. How are such datasets shared on and archived by these researchers? Sharing here means directly passing these datasets on for use by others, while archiving preserves them for potential future uses. Both practices potentially advance reproducibility and comparability, reduce digital divides in data accessibility between researchers and research groups, and save time and money in data collection; they are also increasingly important as the platforms lock down access to their data.

Researchers frequently lament the general absence of established data sharing and archiving protocols. These remain underdeveloped in part because of the ethical and legal challenges inherent in sharing datasets; the problems in establishing clearly defined and described archives for social media data, in the absence of universally accepted standards; the lack of search functionality for archived datasets; the diversity of the social media datasets collected using different methods and from various, continuously evolving platforms; and in some cases even a lack of motivation for researchers to share their data.

The next speakers in this iCS Symposium are Anamaria Dutceac Segesten and Michael Bossetta, who describes the decline of API access as a possible blessing in disguise, as it forces us to explore new and additional sources of data on online communication. One approach to doing this is to pursue academic partnerships with commercial enterprises – for instance, with news publishers or civil society organisations.

The next iCS Symposium session starts with Fabio Giglietto, presenting his team’s results on the use of social media in the March 2018 Italian election. The project’s aim was to comprehensively examine the role of social media during the election, focussing especially on social media audience engagement with the various media sources available.
