Together with Bastian August and Brogan Latil, I spent decidedly too much time trying to understand how Andrew Tate remains present on YouTube after his two channels were suspended.

Digital rhythmanalysis emphasizes time before space and can study moments of (viral) intensity as well as everyday digital life. We bring our framing in dialogue with recent 'affective' and 'aural' turns and discuss practical examples on how to operationalize it (led to this funky baby graph).

How to move along with the audiovisual, vibey, and AI-infused feeds of today's platforms? In this new article with @ddzeeuw.bsky.social and Tommaso Venturini, we theorize 'digital rhythmanalysis' as a potential new quali-quantitative approach to measure and 'feel' rhythms online: bit.ly/pns-dra

4CAT now contains everything for quite sophisticated classification pipelines with humans and (local) LLMs!

I myself used it to classify what types of migration were mentioned in Dutch news articles (see www.groene.nl/artikel/onde...).

Voor @groene.nl onderzochten we hoe het migratiedebat de laatste jaren is gegroeid, verhard en verbreed. We analyseerden 150.000 nieuwsartikelen en 20.000 Tweede Kamer-spreekbeurten en gebruiken een (lokale!) LLM om te zien welke migratietypen de meeste aandacht kregen.

On election day, AI Overviews are still erratic, shown in ~10% of our queries. Some issue-related queries are unanswered but "which party is for defence" recommends VVD and JA21 at the top and includes outdated stances on JSF investments and the PvdA as a separate party. Nothing on NATO norms.

When searching for thematic questions (e.g. 'who should I vote for if I want less taxation'), the D66 party website ranked as the top source, cited even more than Wikipedia.

Google zet gekleurde AI-antwoorden midden in campagnetijd aan, uit, en weer aan GroenLinks-PvdA, D66 en de VVD worden in de antwoorden op algemene politieke vragen het vaakst genoemd. Kleinere partijen komen veel minder vaak aan bod.

With @best.wel.moe and @nieuwsuur.nl, we studied Google's AI Overviews for political searches in the NL. We found that larger parties often benefit and that Google changed its use of AI Overviews *three times* during the run-up to the Dutch elections.

'Nederlandse universiteiten schuwen debat met andersdenkenden' Is er op Nederlandse universiteiten nog wel ruimte voor een open debat? "Radicale vrijheid van meningsuiting bestaat in Nederland niet."

Dit is de omgekeerde wereld. De academische vrijheid wordt bedreigd doordat onze onderzoekers die zich uitspreken in het publieke debat over β€œomstreden” onderwerpen als snel het doelwit worden van online bedreigingen, met name uit extreemrechtse hoek.

The last few weeks I worked 4CAT's LLM features. We're not free from Silicon Valley APIs yet, but you have more options in terms of providers (including Mistral) and it's also possible to use local LLMs through LM Studio and Ollama.

This was also one of the more interesting methodologies I've worked on. We sourced ~3000 questions from 4chan and leftychan, rephrased them through LLMs, queried them on Google and Bing, and scraped the SERP contents through Selenium, 4CAT, and Zoekplaatje.

Google relies heavily on Reddit, showing up in 75% of SERPs(!). Controversial topics that are not enriched are thus often "relayed" to the amateur interpretations of Redditors (see below).

We call for continued SERP audits to interrogate the volatility of enrichment amidst changing political tides.

We find that controversial searches get less components. Some keywords were even blacklisted from enrichment altogether, including "trump" and "biden".

This suggests Google and Bing tend avoid burning their fingers on certain political topics, raising concerns on the reliability of these systems.

πŸ”ŽNew paper! GuillΓ©n Torres and I study "enrichment" on Google and Bing as a form of content moderation.

Main finding: enrichment can be erratic, with components like "AI Overviews" even being banned for certain political queries like those including "trump".
