Social Media Network Mapping

And the final speaker in our panel at the Social Media & Society conference is Risto Kunelius himself, focussing particularly on the loss and damage community which also emerged from our practice mapping of the COP27 climate summit Twitter data. COP27 instituted a Loss and Damage fund as a milestone outcome; this recognises the common but differentiated responsibilities and respective capabilities across countries, and emerges from a much longer debate about climate change responsibility and justice.

This project filtered the COP27 dataset for mentions of the loss and damage efforts, then, and explored the dominant (and absent) actors and content …

The next speaker in our panel at the Social Media & Society conference in Glasgow is the great Barbara Pfetsch, whose focus is on the issue spaces represented in these datasets on COP26 and COP27. Climate change is of course a planetary issue, and how it is addressed is linked to the transnationalisation and translocalisation of digital public spheres; such practices show that space is socially constructed, as are perspectives of the geography of responsibility and impact, which leads to a kind of discursive geography. There is a need here, then, to map the attention economy of climate change.

I was the next speaker in this panel at the Social Media & Society conference in Glasgow, presenting our analysis of the COP26 and COP27 summits through our practice mapping approach. Here are the slides:

We have one more paper session on the final day of the Social Media & Society conference in Glasgow, and it’s a panel coordinated by the great Risto Kunelius that I’m also presenting a paper in. This panel presents outcomes from the CLOUD-C project, which explored discussions around the COP26 (in 2021, which of course took place in Glasgow, too) and COP27 (in 2022, in Sharm El-Sheik) UN climate change summits from a number of perspectives.

Risto kicks us off by introducing the panel itself: data for the project were gathered from Twitter using a set of keywords related to …

The next speaker in this session at the 2026 International Communication Association conference in Cape Town is the great Yangliu Fan, whose focus is on cross-positional agreement and disagreement in social media contexts – with a particular focus on climate discourse on Reddit.

The approach here explores discourse features to encode their complexity, structures, and dynamics within a higher-dimensional space. This extracts discourse features from each post and subsequent comments, and examines comments’ agreement or disagreement with the previous post of comments; from the embedding of these features in a higher-dimensional spaces it is then possible to construct several similarity …

The next speaker in this session at the 2026 International Communication Association conference in Cape Town is Calvin Yixiang Cheng, whose focus is on conspiracy theories on social media. These often persist for a very long time, and in their diffusion change their linguistic forms. Such content change may in fact aid in their persistence.

This study examines such language mutation. It works with Twitter data from 2020-22, collecting tweets which match keywords from major fact-checking sources to identify relevant conspiracist posts, and clustered those posts based on the fact-checking information that debunks them. It also identified the shortest possible …

The next speaker in this high-density session at the 2026 International Communication Association conference in Cape Town is Sujin Yoon, whose focus is on group polarisation. Her particular interest is in opinion and structural convergence, and she begins by noting the limitations of studying such convergence in experimental settings; work with observational data is required here, therefore.

Group polarisation means a convergence of groups towards their dominant views; this also conditions Intra-group and inter-group interactions. Emotional factors such as anger and pride can affect this.

The present study examines this for the r/conservative and r/democrats subreddits, over six months in …

The next paper in this session at the 2026 International Communication Association conference in Cape Town is presented on behalf of Chao Wu and Michelle Seelig, and focusses on public discussions of the COP21 (2016) and COP25 (2020) climate conferences on Reddit, with a particular focus on climate-contrarian comments.

Climate-contrarian claims were identified through the CARDS framework and its claims classifiers; this sorts claims into five broad categories of typical climate change-denialist rhetoric. The project then also conducted topic modelling, and clustered topics by their affinity with each other. This showed clear distinctions between the two events, with more issued-centred …

As I wrap up my Mercator Fellowship at ZeMKI in Bremen, I’ve made a side trip to the 2026 International Communication Association conference in Cape Town, which starts for me with a session on the application of network analysis to polarised contexts. We start with Shengyi Gao, whose interest is in group polarisation. She notes the growing fragmentation of social media environments, which creates structural holes in such networks; some users are ‘structural hole spanners’, however, who bridge such gaps by their activities.

The focus here is on Weibo, and the network is constructed from post forwarding activities; the posts …
