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 …
And the lucky last speaker in the final session at the Social Media Access Days at the German National Library in Frankfurt is the excellent Giada Marino, whose interest is the operation of data access provisions under DSA Article 40.12. The focus here is on very large online marketplace platforms and the systemic risks they pose to minors.
Article 40.12 addresses access to publicly available data from Very Large Online Platforms and Search Engines; this is coordinated across EU jurisdictions by the Expert Group on Access to Publicly Available Data (ECAT). The present project focusses on marketplace platforms such as …
The final session at the Social Media Access Days at the German National Library focusses on the question of systemic risks, which is a key criterion for the approval of DSA data access requests under EU regulations. We start with Hanna Gawel, whose interest is in archiving hacktivism as a part of digital heritage. Hacktivism may be regarded as a high-risk activity, and therefore requires particular care from archivists.
The content to be archived here might include screenshots of defacements, leaked manifestos, memes, protest videos, and various other forms of often very ephemeral materials; there is a need to create …
The final speaker in this session at the Social Media Access Days at the German National Library is Susmita Gangopadhyay, presenting a project that has engaged in a continuous crawl of Telegram’s public channels. Telegram is a platform that has grown substantially in recent years, with some 950 million users.
The platform has an API which can be used to gather data from the platform, and this tends to focus on groups (which are many-to-many, may be public or private, and have distinct administrators) and channels (which are one-to-many only, with named administrators). Otherwise there are some functional similarities between …
Up next at the Social Media Access Days at the German National Library is Ramin Soleymani, whose focus is on the analysis of social media content from a social ecological perspective. The use of social media has enabled digital nature experiences, somewhat making up for an overall decline in the direct nature experiences of an increasingly urban population; this might lead to the emergence of digital relational values including seeding, spreading, and grounding.
Relational values are a relatively new concept in the science policy arena; they complement nature’s instrumental (extractive) and intrinsic (inherent) values. Relational values refer to the relationships …
The next speaker in the morning session at the Social Media Access Days at the German National Library is Veronica Batzendorfer, whose interest is in the Xitter-adjacent Grokipedia project as an ‘alternative’ to Wikipedia. Specifically, her focus is on semantic drift across Grokipedia’s versions, starting with material drawn in part from Wikipedia and then rewritten by LLMs.
Such semantic drift can be examined through a geometric framework. This works with two points in time and explores changes between them, across Wikipedia and Grokipedia; Wikipedia content serves as the training data for the LLM which generates articles for the Grokipedia, so …
The third and final day at the Social Media Access Days at the German National Library starts with a paper by Alexander König, whose focus is on metadata for social media data. Creating quality metadata is critical for the appropriate storage and reuse of datasets, and especially so for social media dataset as the conditions of the data gathering and the state of the platform at the time of gathering also need to be captured in the metadata.
The CLARIN Knowledge Centre for Computer-Mediated Communication and Social Media Corporate (CKCMC) is currently developing a metadata standard for such data, incorporating …
