Using data to expose violations of transgender rights
Friday May 29, 2026 2:00pm - 3:15pm CEST

Reporting on transgender people can be a minefield: official data is scarce, public understanding is patchy, and with their rights increasingly contested by politicians and commentators, the community itself is often wary of journalists. Drawing on Investigate Europe’s project The Cruel Condition -published with Arte, New Lines, Taz, and others- this session explores how laws across Europe...

Coding has long been a skill journalists wanted to learn to make their investigations more efficient and rigorous. The main barrier was the significant time investment required to develop that skill. But since large language models emerged, we no longer need to write code ourselves. We do, however, still need to make informed choices when instructing an LLM to write code for us. Otherwise, those...

Unlocking the apps: How can you scrap data, trace leaks on mobile and turn it into stories
Sunday May 31, 2026 9:30am - 10:45am CEST
1.14
Much of modern life is mediated through phones and apps. To investigate anything they touch, you need to understand where these apps' data comes from, what they're sharing, and with whom. But while network forensics & scraping for the web have received plenty of attention, the same isn't true for mobile, where techniques can be more challenging and clear guides are harder to find. In this talk,...

Text embeddings: navigating text in high dimensions
Sunday May 31, 2026 11:15am - 12:30pm CEST

Most "big data" problems in journalism aren't really data problems, they're reading problems: a big leak, a ministry dump of 12,000 pages, or a FOI coming back as zip of PDFs. The instinct is to search, but keyword search assumes you already know what you're looking for. Which sometimes is the thing you don't know yet. This session introduces embeddings: a technique that turns any text into a...
