'Big Data'

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 …

And the next speaker at the Social Media Access Days at the German National Library is Beatrice Cannelli, whose interest is in how national memory institutions’ social media archiving initiatives have been affected by changing data access regimes. Such activities are affected by national legal frameworks, available resources, collection policies and scope, technical limitations, and the Terms of Service of the various platforms.

The latter are justified by user privacy concerns and the protection of sensitive information, but in practice mostly protect the platforms’ own business interests. How these are formulated influences the extent to which content from such platforms …

The post-lunch session at the Social Media Access Days at the German National Library starts with LK Seiling and Sophia Graf, who discuss the Weizenbaum-Institut’s DSA40 Collaboratory project. The EU’s Digital Services Act provides for research access to public and non-public data via its articles 40(12) and 40(4), and in both cases this is limited to research that investigates what is called ‘systemic risks’, and to Very Large Online Platforms which serve at least 10% of the EU population, which translates to 45 million users.

If platforms are found to have failed to provide such access, the EU can (and …

The next speaker at the Social Media Access Days at the German National Library is Robert Jäschke. He begins by noting the legal constraints on social media data sharing, including Terms of Service, copyright, and other restrictions. One approach to managing this is the way Twitter approached this: sharing datasets with lists of tweet IDs without any further content was allowed, and researchers then needed to ‘rehydrate’ them by regathering the tweet data. Another approach is to share only aggregate metrics rather than the source data themselves; or to share derived datasets (like term matrices, n-gram datasets, or word embeddings) …

Day Two at the Social Media Access Days in Frankfurt starts with my keynote, taking stock of how we access and engage with social media data nearly ten years after the drastic changes to many platforms' data access regimes following the 2018 Cambridge Analytica scandal. Back then, I wrote an article for Information, Communication & Society about the APIcalypse; how have things developed since then?

Here are my slides from the talk:

The second session at the Social Media Access Days at the German National Library begins with a paper by Mia Berg and Oliver Vettermann, whose focus is on social media data scraping, with a particular focus on TikTok. TikTok does offer an API for data access (at least in Europe), but unfortunately it remains severely limited and unreliable; this is problematic given that many user practices and content formats are in urgent need of further analysis. One example of such a content genre is AI-generated video content, such as POV videos that purport to imagine historical situations.

Manual data gathering …

The next speaker in this session at the Social Media Access Days at the German National Library is Katharina Maubach, whose focus here is on data formats for archiving social media data. She works with a project exploring liking activities on social media platforms, especially relating to content from news sites; this covers Disqus, Facebook, YouTube, Xitter, and Instagram.

Ideally, such a cross-platform dataset should be shared with other researchers under FAIR principles (findable, accessible, interoperable, and reusable), but under the Terms of Service of such platforms and their data access conditions this is very difficult; the focus of Katharina’s …

And next up at the Social Media Access Days at the German National Library are Marco Wähner and Jan Dennis Gumz, exploring the further use of Wikipedia data on the early German federal election in 2025. Because of the unusual circumstances of the election, following the failure of the governing coalition, there was an increased need for information about the election amongst voters, and Wikipedia (as the only public-interest Very Large Online Platform classified by the EU) played an important role here.

But as a collaboratively edited online platform, Wikipedia represents a particularly special information ecosystem; editing activity here also …

The second day at the ZeMKI 20th anniversary conference in Bremen starts with a keynote by Nick Couldry, focussing on the corporatisation of media and everything. He notes a number of key changes over the past twenty years: datafication – the transformation of everyday life into data, and its exploitation by business and government, thereby producing the social for capital; social media – shifting the exploitation of social data to produce attention and shape consumer and citizen action; and artificial intelligence – the corporate capture of the human mind itself, which automates cognitive production and transforms what we value.

After the great excitement of AoIR 2025 in Rio de Janeiro, I’m now at my final stop on this conference trip, at the ZeMKI 20th anniversary conference in Bremen which promises to be an equally stimulating event. The theme here is “20 years into the future”, and we start with a keynote by the great José van Dijck. Her focus is on digital sovereignty in Europe under the current and emerging global circumstances.

This responds to the platformisation of public communication in society; public participation via platforms is possible only after signing up to one or more (US-headquartered) platforms, for …
