Masterclass: Hack your way into a big dataset with R (Masterclass ticket needed)
Thursday May 22, 2025 10:00am - 12:00pm CEST

A separate ticket is required to attend this masterclass. If you would like to attend but haven't yet purchased a ticket, please contact us at info@dataharvest.eu

R is one of the most useful programming languages in data journalism. You may have heard of it, maybe even tried it a little and found the learning curve too steep. If so, this session is for you.

We are going to spend the day looking at European Environment Agency’s EPRTR (European Pollutant Release and Transfer Register) data – it’s a lot of data, and some of it is quite messy. It contains dozens, probably hundreds, of potential lines of investigation to be explored – and that’s what we’re going to do.

By the end of the day, you will know how to import data in an R environment, filter it, reshape it, and interrogate it. You will be able to make some basic graphs. Above all, you will be on the way to finding stories in the day’s chosen data, and be able to take your script away and use it again, or adapt it to other datasets. And, we hope, you will have the beginnings of a story idea.

We will assume that you are familiar with spreadsheets, but that you have no knowledge of R. You will not need to install anything – everything will be run on cloud instances of R.

If you’re already advanced with R, it is still worth coming along to use and share what you know, to support others, and to learn something new.

(If you already have a dataset you want to work with – bring that too!)

Investigations coordinator - one title, multiple realities
Friday May 23, 2025 1:15pm - 2:30pm CEST
Cross-border collaborative investigations are now an established practice in journalism. As this field evolves, the role of investigation coordinators has become better defined, even moving towards professionalisation. With the proliferation of organisations and journalists working on cross-border investigations, various coordination models have emerged, each presenting unique challenges and opportunities.


Some organisations have staff coordinators, with a focus on coordinating team members, while they are supported in handling admin, logistics, and finance. In other cases, the coordinator is a freelancer, managing all aspects of work independently, or a newsroom staffer receiving limited assistance from their newsrooms. In this session, three experienced coordinators will discuss the different challenges and opportunities that come with their role.

The EU hands out over a third of its budget to the agricultural sector every year. Under EU law data on subsidies are publicly available via the individual member states. However, the information is often difficult to access, analyze and compare across borders. The Farmsubsidy.org website contains fresh and searchable data on farm subsidies, obtained from national government agencies. In this session, you will learn:
- what's in the farm subsidy data ,- how to look through millions of recipients of farm subsidies; - crossmatch with other data to find story leads; - how to classify types of recipients (person/company/etc.) using machine learning models.

Beyond the pixels: the power of raster data in QGIS
Friday May 23, 2025 1:15pm - 2:30pm CEST
Manipulating and analyzing raster data can be intimidating, as it often appears more complex than vector data. However, raster data—such as satellite imagery or forest loss information—is essential for environmental and geographic storytelling. For example others, it enables journalists to assess vegetation health, visualize floods or droughts, and calculate deforested areas, even when true-colour satellite imagery is obscured by clouds.

In this hands-on session, participants will learn the key functions in QGIS needed to work with raster data. This includes loading raster layers, managing projections, setting band combinations (such as false color) for analysis, styling raster layers to enhance visibility, and performing raster calculations.

To attend this session, participants should have basic QGIS skills.

Before the session, please install QGIS on your laptops and make sure it is working properly. Download from: https://www.qgis.org/en/site/forusers/download.html

Mapping independence: why and how newsrooms should host and style their own maps
Friday May 23, 2025 1:15pm - 2:30pm CEST
Tired of Google Maps' branding and tracking? In this session, we’ll explore how newsrooms can host their own map tiles using open-source tools such as Protomaps and OpenFreeMap. We’ll look at how to reduce costs, protect reader privacy, and gain full editorial control — alongside a hands-on workshop on customizing map styles with Maputnik. No prior knowledge is required for the workshop, though some experience working with maps will be a bonus, especially for the self-hosting part. The workshop takes place entirely in a browser. After this session, attendees will be familiar with alternatives to commercial map providers and know the foundations of map styling and self-hosting, empowering them to create maps that better serve their reporting and storytelling.

🤖 How LLMs can classify thousands of records in minutes
Friday May 23, 2025 1:15pm - 2:30pm CEST
You find yourself staring at a dataset with tens or hundreds of thousands of rows. Maybe you want to get up-to-date FOIA contact details for all government departments in your country, or to find out which political donors have links to the fossil fuels industry. What do you do?

Large Language Models (LLMs) can help journalists automate simple research and classification tasks that would take an unreasonably long time to do manually.

In this session, we'll outline how Global Witness has used LLMs, search engines and web scraping to help us identify fossil fuel lobbyists at COP29. These techniques can be applied to other investigations and research tasks.

The workshop will cover:

- An interactive classification demo
- Some basic tips on setting up a research/classification project
- The challenges of doing AI research at scale and how to address them
- Using more advanced tools

After attending this session, you will be able to take an existing dataset and automatically augment it with new data, opening up the potential for new stories and investigations.

If you want to follow along with the classification demo, you'll need to be able to run Jupyter Notebooks on your device or have a Google account. A basic understanding of Python would be useful, but we won't be writing any new code.

Media start-ups - how the bumble-bees fly
Friday May 23, 2025 1:15pm - 2:30pm CEST
All over Europe, small, independent media outlets are emerging, countering the decline in traditional media and the rise of misinformation. But they are still outnumbered and face significant challenges to their survival.
For the first time, facts about this new sector have been collected: a survey of 174 newsrooms from 31 European countries has pulled together knowledge about these small, often non-profit newsrooms. The survey, conducted by Netzwerk Recherche, shows fiery souls, great enthusiasm and professionalism, but also big challenges in funding and sustainability. What is the situation? Are some business models more suitable than others? What should be done to support the sector – and where could support come from?

Deregulation and a "Clean Industrial Deal" – how to cover the new pro-corporate EU agenda
Friday May 23, 2025 1:15pm - 2:30pm CEST
The new European Commission's focus for the next five years will be on boosting industry's "competitiveness". This entails a radical deregulation agenda for rules that industry perceives as burdensome. Von der Leyen's deregulation agenda was heavily inspired by corporate lobbying campaigns. Last year, the chemical industry led on the Antwerp Declaration, a wish list of industry to slash regulations. This is now followed by the 'Clean Industrial Deal' which is pushing fossil gas for hydrogen, and ignores the other planetary crisis: pollution and biodiversity decline. CEO has compiled an initial list of more than 15 different tools for systemic deregulation. These create more hurdles for new progressive EU regulation, and create escape routes allowing companies to avoid regulation, as well as new hurdles for national level regulation. A good example are the Omnibus proposals, the first of which diluted sustainability reporting rules that had only recently been agreed. We'll share our insights on these new developments in the deregulation agenda, assess what's at stake, and how to build stories around them, at the European level and in your country.

Investigating far-right networks: uncovering extremist groups and international campaigns to curtail women’s rights
Friday May 23, 2025 1:15pm - 2:30pm CEST
I'M WAITING FOR THE SPEAKERS TO CONFIRM THE TITLE AND DESCRIPTION Far-right and other extremist networks in Europe organise themselves and coordinate their activities across borders by using different technological and strategic means, and pursuing different social and political goals. In this session, two (or three, or four) journalists will explain the diverse methodologies they employed to investigate how powerful hardliner networks operate in Europe.

Brecht Castel will describe how he and his colleagues used OSINT techniques to uncover how Active Clubs -- which mix fitness and martial arts with far-right ideology -- recruit and radicalise their members online. And Gabriela Keller will explain how she and her colleagues investigated how the international religious right has built cross-border alliances with civil society and political actors, with the aim of influencing policy and restrict women's reproductive rights.

By attending this session, you will learn different approaches to think of and plan a collaborative investigation into the activities of extremist networks.

Working with whistleblowers
Friday May 23, 2025 1:15pm - 2:30pm CEST
Whistleblowers can be vital sources for journalists, and their information has initiated some of the biggest investigations. But whistleblowers are running big risks – from personal safety to legal threats. What do you do as a journalist if you are approached by a whistleblower? How do you get and verify the information you need while still keeping your source secret and safe? And what protection exists for these people who shed light on conditions that were meant to be kept hidden? Join this conversation between a journalist with long experience of working with whistleblowers and secret sources and a specialist in the protection and legislation around whistleblowing.

Pathways to collaboration with scientists: networking roundtable about cross-disciplinary collaboration
Friday May 23, 2025 1:15pm - 2:30pm CEST
In recent years, cross-border investigative projects have increasingly seen scientists and scholars not just as interviewees but as active collaborators throughout the investigative process. Such collaborations, while powerful, require careful design from the start. For example, scientists and journalists often have diverging agendas, timelines, and constraints. There is an inherent imbalance between scientific expertise and the ability of journalists to critically evaluate the validity of a specific scientific approach, leaving journalists reliant on scientists' judgment and at risk of losing control over the direction of the investigation. To address these and other challenges there is a need for structured guidelines, recommendations, and potentially a code of conduct to ensure independence, equity, and effective use of resources. In this networking session, the participants will discuss what those guidelines might look like and co-create a practical blueprint for fostering respectful and productive collaborations between journalists and scholars. The session's outcome will be a co-created roadmap of suggestions, insights, and practical recommendations.

How to track AI extractivism practices through data annotators
Friday May 23, 2025 3:00pm - 4:15pm CEST
Large language models and other AI systems sometimes only work because there are thousands of people labeling and classifying information that is then used in training the models. Journalistic investigations are discovering rights violations and misdemeanors by large outsourcing companies, who offer jobs below the minimum wage. In some cases, workers are forced to go through datasets of disturbing data that can affect their mental health. However, tracing this labour chain is not easy. Big Tech companies often turn to underdeveloped countries where they can take advantage of economic conditions and labour needs to employ this activity; scammers take advantage of this under-supervised process. How can you track this outsourcing chain when you are sitting at your desk somewhere in Europe? Journalists who attend this session will learn how to investigate large tech companies and follow the traces of their activities, as well as uncovering labour and human rights violations along the AI supply chain. They will also learn how to contact the right sources and approach workers who are in sensitive situations.

How to track supply chains and money flows in Europe that contribute to environmental destruction in the Global South
Friday May 23, 2025 3:00pm - 4:15pm CEST
The choices made by consumers, corporations, and financiers in the Global North ripple across borders, often shaping the lives and environments of communities in the Global South. From sourcing raw materials to funding large-scale projects, some decisions result in exploitative practices, environmental degradation, and corruption in vulnerable regions. Journalism can play a critical role in unveiling these hidden connections by tracing supply chains and financial flows. The data and research team from the Pulitzer Center will share the techniques, data and tools they used to help journalists uncover the supply chains and financial enablers behind commodities and projects that contributed to environmental degradation and human rights abuse in the Global South. This session will dive into the reporting methodologies behind environmental investigations on rainforest and ocean issues that the team has conducted. The team will provide participants with an investigative framework and introduce them to both the open and private databases and tools used for such investigation. The purpose of this session is to allow participants to replicate the methodologies for their own investigations and to have practical guidelines to kickstart such investigations.

Find the Eurostat data you want - using an API
Friday May 23, 2025 3:00pm - 4:15pm CEST
Getting European data from EUROSTAT, the statistical office of the European Union, can be tricky, clicking through ever-increasing menus and confusing download buttons - but there is an easier way. Instead of manually downloading spreadsheets, we will learn how to use the API provided by Eurostat. Once you know how this works you will be able to adapt your knowledge to query data from other organizations including the OECD and the World Bank. We'll also learn how generative AI can help simplify querying data in this format by ensuring we use the correct syntax.Bring your own laptop: we will be using some Python: you will need a gmail account in order to access a copy of the script for the session. No other software is required.

Browser puppetry: Playwright for dynamic website scraping
Friday May 23, 2025 3:00pm - 4:15pm CEST
Playwright is a next-generation browser automation tool that allows you to use Python or JavaScript to scrape almost any web page. It can assist in downloading pages of government documents, capturing tweets before they get deleted, or simply breaking past the cookie consent banner. Beyond the basics, it can also easily take screenshots, monitor and log network requests, and even fit right into your traditional BeautifulSoup scraping approach.

We'll look at:

- Installing Playwright
- Accessing elements on the page
- Interacting with web pages (clicking, navigating, filling out forms)
- Taking screenshots
- Sending pages to traditional scraping tools like BeautifulSoup
- Common patterns including pagination and CAPTCHA breaking

For those of you familiar with tackling similar problems using Selenium: Playwright is a similar tool with a better interface, better install/upgrade process, and ten times the usability. It might be time to upgrade!

Participants should have a basic knowledge of Python and HTML, but we'll also cover how to breeze past those basics with AI assistance. To fully participate, participants should have Jupyter installed. Additional software and installation tips will be available at https://github.com/jsoma/dataharvest25-playwright-scraping

Cracking the code: how to use RegEx in your investigations
Friday May 23, 2025 3:00pm - 4:15pm CEST
When you unlock the power of regular expressions (RegEx) you supercharge your spreadsheet!

Participants will learn how to extract hidden patterns from text, clean messy datasets, and automate repetitive tasks using the RegEx formulas within Google Sheets (but this session is also a good intro if you want to apply it in other code).

Through practical examples—like extracting donations, cleaning salutation-heavy lists, and extracting postcodes—you will leave with the confidence to apply RegEx in your day-to-day data work.

Attendees will receive a RegEx cheat sheet (customisable for their own use) and a practical demo spreadsheet to take their skills to the next level. No prior experience of RegEx is required, but you should be comfortable writing formulas in Google Sheets/Excel. I will be sharing a Google Sheet containing the data for which you will require a Google account.

Public interest journalism – where does Europe go?
Friday May 23, 2025 3:00pm - 4:15pm CEST
Independent newsrooms are sprouting up all over Europe. Countering the decline in traditional media and the rise of misinformation, they are still outnumbered and face significant challenges to their survival. The Journalism Value Project (JVP) aims to advance knowledge of and debate around Europe’s independent media. As part of advancing the debate, the JVP partners have consulted with stakeholders from multiple sectors to better understand how they view, value and support journalism now and in the future and how public interest journalism is bringing social, cultural, democratic, and financial value to their community and society at large.
The Journalism Value Project (JVP) has put the spotlight on the societal value of independent journalism and the challenges it faces. The project includes a whitepaper about the needs of the future: Is there a place for these media? Are they a priority for funders, or for politicians at national and EU level? Must the newsroom find their own ways to become sustainable?

Taking OSINT to the archive: using data, OSINT and (a little bit of) AI for historical investigative journalism
Friday May 23, 2025 3:00pm - 4:15pm CEST
In a world where history may sometimes seem busy repeating itself, the ability to find your way around traditional paper archives is increasingly useful. Whether it’s war, genocide, the Cold War or the environment: historical stories are becoming more and more – well – current.

In this session we’ll show you how to transfer data and OSINT skills to working with paper and historical records. We will explain how to find stories in the material and how to find both historical and current sources. We’ll show you some – hopefully – inspiring examples, and we’ll discuss why it’s not smart to accidentally download 500,000 records from the National Archives.

Keep calm and coordinate: Networking Roundtable about coordinating collaborative investigations
Friday May 23, 2025 3:00pm - 4:15pm CEST
Cross-border collaborative investigations are now an established practice in journalism, and the role of coordinator is gaining a clearer definition. Yes, many questions about the coordinator's role and work remain open, as each investigation is different and presents different challenges. While some organisations specialise in hosting and coordinating collaborative projects, there are also many cross-border investigations coordinated by individual journalists in an ad-hoc manner. In this session we'd like to consider the possibility of developing a cross-border editorial framework and mindset that would help us decide which topics to investigate from the beginning of a collaboration. We will look at ideas on how to best manage diverse, cross-border teams who have varying cultural and journalistic backgrounds; how to work remotely across different time zones with freelancers and staffers, newcomers and veterans, data journalists and writers. When it comes to publishing partners, how do you navigate the varying requirements of legacy media and independent newsrooms?

Risk and rewards: how to hunt for sanctions evasion in customs data
Friday May 23, 2025 4:45pm - 6:00pm CEST
Customs records and open-source databases are a goldmine, but they can also be overwhelming. With so much data, where do you begin looking for stories? How can you be sure that what you're seeing is what you think it is? And how should you organise your findings once you have a good lead?

At a time when international sanctions affect everything from oil to aircraft parts, this presentation offers insights into investigating sanctioned goods, sharing information on the databases and tools and techniques useful for finding original supply chain stories. We will be drawing on our experience of tracking shipments of aircraft parts from western facilities to Russia via India (see: https://www.investigate-europe.eu/posts/boeing-airbus-russia-sanctions-aircraft-parts-india-intermediaries).

Investigating built expansion on protected natural areas 🌳: learn the basics of PostGIS
Friday May 23, 2025 4:45pm - 6:00pm CEST
Working with geospatial datasets is often critical to investigations dealing with where things are located, where an event occurred, land ownership, and the environment.

In this workshop, participants will learn the basics of using PostGIS to query and join geospatial datasets using the Arena+ "Europe in Grey" investigation as a case study.

We’ll run through a brief overview of PostGIS, the spatial data types, indexes, and functions it adds to Postgres, and a few of its strengths and weaknesses as a tool.

Participants will connect to an existing database containing a dataset of built expansion in Europe and a few datasets used in the Arena investigation. They’ll be guided through writing queries to reproduce some of the investigation’s results, answering questions like:
Which European country has lost the greatest proportion of its wild areas since 2018?
Which protected areas have had the most building on them?

To take part in this workshop, participants should feel comfortable writing basic SQL queries.

The vertical perspective: best practices for using satellite data in journalism
Friday May 23, 2025 4:45pm - 6:00pm CEST
Satellite data has become a powerful resource in investigative journalism—but using it effectively comes with technical, ethical, and practical challenges. This session draws on several recent investigations to highlight how journalists are incorporating satellite imagery and geospatial data into their reporting.

We’ll explore how radar-based analysis was used to document destruction in Ukrainian cities, and how satellite-derived location data revealed movement patterns of German intelligence service employees. These examples show not just what’s possible, but also what can go wrong—and how journalists adapted when it did. From sourcing the data to picking the right tools and interpreting results responsibly, the session offers real-world insights into the craft of satellite-aided investigations.

No technical background is required. This isn’t a hands-on workshop, but a behind-the-scenes look at how satellite data fits into newsroom workflows.

The JuicyFields story - investigating the largest cannabis fraud of all time
Saturday May 24, 2025 9:30am - 10:45am CEST
Russian gangsters, fake counts, golden Ferraris and shell companies in Liechtenstein and Switzerland. Investigating the JuicyFields case meant plunging into a wild maze of deception, false leads and spectacular turns. Hundreds of thousands of people were deceived by a group of serial scammers. They claimed everybody could become rich by investing in virtual cannabis. With losses amounting to more than half a billion dollars, the JuicyFields scam is one of the largest pyramid schemes ever investigated by European authorities. Gabriela Keller (Correctiv) and Elisa Simantke (Paper Trail Media) were part of an international team of journalists that uncovered how a bunch of criminals from Russia went on digital raids targeting Europeans again and again. In this panel, Gabriele and Eilsa will explain how they built up sources, what they learnt from OSINT and police documents, how they tracked the path of the criminals from St.Petersburg to Berlin, Switzerland and South America. They will also talk about how they analysed company structures – and learned how to avoid the traps set for them by the criminals. Because, as the investigation built up momentum, the fraudsters were trying to lure the reporters into their network of illusions. And while the JuicyFields website is now defunct, the masterminds behind it are setting up new scams. The business of the fraudsters continues in several countries – as is the international investigation. That means reporters can still learn how to carry on investigating in their own country.

From source to chart 📈 : Using free tools to automate your data flows
Saturday May 24, 2025 9:30am - 10:45am CEST
DESCRIPTION:

For monitoring purposes and to inform our reporting, it’s helpful to keep an eye on trends over time in some datasets, for example when tracking the progress of an mpox outbreak, monitoring pre-election polls or investigating migration trends.

This is where automation comes in handy: with the data being automatically grabbed from the source, reconfigured and channeled into a chart for visualization, allowing data journalists and their colleagues to notice report-worthy trends early on.

To establish such a workflow, we have been relying on free tools like Datawrapper and Github Actions to run a Python script.

Participants will be guided through setting up such a workflow step-by-step.

LEARNING OBJECTIVES:

🚀 In this session you will learn how to...
- collect data from a url
- parse the data into the needed format using Python's `pandas` library
- use Python's `datawrapper` library to create a chart
- set up the script to run automatically on Github Actions

🔍 PREREQUISITES & TOOLS:

- ✅ Datawrapper API token
- ✅ Github Account (if you want to automate the chart update)
- optional: Code text editor (if you prefer working with your own code for automation), such as Atom or Sublime Text
- optional: Distill browser plugin (if you want to update on click)
- optional: basic understanding of Python/coding helpful, but not required

Python Without the pain: write code with LLMs
Saturday May 24, 2025 9:30am - 10:45am CEST
In an age where data is an important part of impactful storytelling, journalists need tools that enable them to work with it effectively. Python is a powerful resource for analyzing and visualizing data, but it can be intimidating for those without a technical background. This workshop breaks down those barriers, showing how AI tools like ChatGPT can make coding basics approachable and accessible. By equipping journalists with these skills, the workshop aims to empower them to create richer, data-driven stories and visualisations without relying heavily on external technical support.

The session will start with an overview of Python and how AI-assisted coding works, showcasing how these tools can simplify technical challenges, followed by real-life examples. Afterward, participants will dive into a hands-on session using Jupyter Notebook to practice running and adapting Python scripts. By the end, they’ll feel more confident tackling technical problems independently.

Participants are encouraged to have Python (with Jupyter Notebook) installed on their devices, or a Google Collab environment ready. You will also need a ChatGPT account set up before attending. While familiarity with Python is helpful, it’s not required.

Teaching LLMs to build your Machine Learning Models
Saturday May 24, 2025 9:30am - 10:45am CEST
In this practical session, participants will learn how LLMs like ChatGPT can assist in writing machine learning code for journalistic investigations.

We’ll start by prompting ChatGPT to generate code for analyzing a small dataset. Then, we’ll apply the code to a larger dataset locally. After attending this session, participants will be able to train and use this machine learning model on their own.

This method was used by Frontstory.pl to analyze thousands of messages on Telegram and reveal the scale of drug trafficking activity in Poland.

To follow along, participants should be comfortable using Python and Jupyter Notebook.

Welcome to the Brussels bubble: tips on how to investigate the EU
Saturday May 24, 2025 9:30am - 10:45am CEST
Many journalists get lost trying to find information and data quickly in the institutional labyrinth that is the European Union. Finding specific amendments, understanding the issues surrounding a piece of legislation, establishing the position of specific member states in negotiations or the approach of the European Commission... so much information is unknown or inaccessible to the layperson - who will easily become discouraged from pursuing their EU investigation.

In this session, we will will use concrete and practical examples to show you how to navigate the institutional triangle (Commission, EU Parliament and the Council), as well as the Court of Justice of the European Union. We'll explain how to track the European legislative process, quickly find the relevant players, information and data you need. This won't be an ex-cathedra lecture, but a practical deep dive session, with, as a take away, a list of useful links organised according to journalistic needs. After the session, you are also welcome to join us in the EU Cafe corner for a further discussion or get your specific EU questions answered.

Beyond bars and pie charts: creative and interactive data storytelling
Saturday May 24, 2025 9:30am - 10:45am CEST
Data and visualisations are now everpresent in journalism, particularly in investigations and in cross-border collaborative projects (where often "data" is the common language). Additionally, diverse software and platforms provide us with different opportunities to reach our audiences, who are also more and more used to seeing data visualisations.

In this session we'll ask how we can continue to be innovative and creative in producing and publishing data visualisations, and how we can benefit from developing interactive visualisations, even including simple online games that push the boundaries of data storytelling.

More than just the Wayback Machine: how to investigate deleted and archived content
Saturday May 24, 2025 11:15am - 12:30pm CEST
Even among investigative journalists, web archives tend to be underrated – and undertaught. This hands-on session introduces journalists to powerful techniques for using web archives.
Participants will learn how to recover deleted or hidden content and archive key material from platforms like Instagram and X.
Using real-world examples, we’ll demonstrate how these skills can strengthen reporting across a wide range of stories, from everyday reporting to investigative longreads.
After this session, you will be able to retrieve archived content, recover deleted posts (not necessarily the same things!), and preserve online material using advanced web archiving tools and techniques. We will teach participants how to tweak the URL and use the asterisk, and we will demonstrate why the "Golden Hour" of archiving is so important in breaking news situations.

Saturday May 24, 2025 11:15am - 12:30pm CEST
Funding journalism is a recurring issue. In recent years, we’ve focused a lot on the ’how’: How to phrase an application, how to develop a realistic budget, how to reach out to potential funders. And we’ll continue with that, of course: but the question of how to fund public interest journalism has, if possible, become even more urgent. But we also need a deeper understanding, a shared terminology and fora to discuss these questions.
Brigitte Alfter will talk about the freshly released Arena Paper on fundraising. She is also the author of a GFMD paper on public funding to journalists and has been a speaker at ’Saving Journalism’ events at Columbia University, an annual conference on a wide variety of funding sources and funding models for journalism in our time.
The session will be followed by a fundraising café with advice on your project or for your organisation.

Get off the screen, look me in the eye: offline and in-person journalistic storytelling
Saturday May 24, 2025 11:15am - 12:30pm CEST
Journalism is almost never delivered live. These days, always there seems to be a screen between the journalists and the audience. But before the online and digital world swallowed everything, journalism reached people through the pages of a newspaper or magazine, on a TV screen, or on a crackling radio (if you are too young to know what we're talking about, ask your parents).

It doesn't have to be like that -- even today when most people start feeling sick and anxious at the mere thought of being away from their smartphones for a few hours.

There are offline and in-person ways for us to present, deliver and disseminate our investigations and other reporting. And there seems to be a growing appetite among audiences and (some) media organisations to explore ways to get together and experience journalistic storytelling live.

In this session, three journalists who've been experimenting with different offline and in-person ways of journalistic storytelling will share their experiences, the lessons learnt, and how it feels to have your audience look you in the eye and talk to you in person as you present or deliver your story.

With the EU’s new AI Act introducing a historic regulatory framework, there are high hopes for greater oversight of artificial intelligence. But significant loopholes remain — especially when it comes to surveillance, policing, and the algorithmic control of workers.

In this session, journalists will share how they’re reporting on AI systems hidden in plain sight — from biometric surveillance to algorithmic monitoring in the workplace. Through these cases, they’ll show how the AI Act opens doors for investigation, while also leaving dangerous blind spots.

Participants will leave the session with practical strategies for reporting on AI and power: how to trace lobbying and regulation, use FOI requests, and uncover the real-world impact of automated systems — even when those in charge prefer to keep them invisible.

How to investigate AI: advanced level
Saturday May 24, 2025 1:45pm - 3:00pm CEST
Investigating algorithms is not just about obtaining code. On the contrary, there's so much we can learn from an automated system – whether Al-driven or rule-based – by looking the impact it has on individuals, minorities and marginalized communities. We can examine the people involved in its development and deployment; the companies who profit; the data it generates; and the weight given to the parameters it relies on to make decisions. How do we find this data and approach the investigation? This session is aimed at journalists with previous experience in reporting about automation and AI and those who attended our beginner level session (Saturday, 0930). In this practical workshop we will explore two real, successful cases of investigative algorithmic accountability reporting. These investigations uncovered how automated systems are used for welfare allocation in different European countries. This will be a hands-on session – don't expect ready-made answers. Instead, all participants will start with the same, limited information about the case. Together, we will explore the different methodologies and approaches we can use to uncover how an algorithm works, even when we have little data to start with. During the workshop, we will aim to obtain as many techniques and methods as possible and inspire new investigations.

Investigating the business of outsourced war crimes prosecutions in Europe
Saturday May 24, 2025 1:45pm - 3:00pm CEST
For the past decade, EU countries have been falling over themselves to prosecute suspected Syrian war criminals hiding in Europe, relying on ‘Universal Jurisdiction’ laws. Among the most prevalent are Germany, France and Spain.

Globally, there are dozens of organisations that claim to hunt down former regime agents, ISIS fighters, and military officials accused of committing serious war crimes before slipping into Europe. These organisations raise millions in government funding and garner significant praise from the world's media.

Behind the scenes, however, we find an untransparent, shadowy alliance between police, prosecutors, and intelligence, with some NGOs blurring the lines between activism and policing. The result is an enthusiastic but deeply flawed application of universal jurisdiction, with a growing trail of ill-fated prosecutions built on flimsy evidence and unreliable witnesses. These have been collected by inexperienced investigators with questionable procedures – and much of this activity is hidden from public view.

There are currently around 120 universal jurisdiction cases across Europe. The fall of the Syrian regime in December 2024 will only increase the need to understand the intricacies of war crimes cases and how to report on prosecutions in Europe.

This session proposes to provide journalists with the tools and prompts to examine cases in their own countries critically. We will tell the journalists exactly how to do this, how to find information and sources, and how to avoid traps, not be drawn in by PR, but to see and assess evidence for what it is.

Scientific laboratory analysis applied to journalism: what you need to know
Saturday May 24, 2025 1:45pm - 3:00pm CEST
Journalists are increasingly using laboratory analyses as part of their investigations. However, they often approach laboratories without fully understanding what this entails. In general, laboratory analyses can be used to trace the origin of goods (food, lumber, or steel) through methods such as DNA or isotopic analysis. They can also be used to analyse environmental matrices, such as water or soil, to detect pollutants. But how exactly does this process work? What are the right “research questions” to ask before contacting a laboratory? Which laboratory should you choose? How much does it cost? How long does it take to get results? And how relevant are these results to a journalistic investigation? These questions are often overlooked. It turns out that laboratory analysis is not a magic wand that can instantly solve an investigation.By the end of the session, participants will have learned simple but essential rules to ensure that laboratory analysis becomes a key component of their investigations—not just a superficial add-on.

Spreadsheets with superpowers: LLMs for data extraction and classification
Saturday May 24, 2025 1:45pm - 3:00pm CEST
Lots of data and investigative journalism takes place in spreadsheets. Frequently, we want to  perform a task for every row in our spreadsheet. For instance, we may have cells containing:

- Quotes from a speech by a European politician that we want to classify into “Pro-EU”, “Anti-EU” or “Neutral”

- Company annual reports from which we want to extract the ultimate controlling party

- Political ads which we want to sift according to whether they mention immigration, directly or indirectly

In this session, participants will learn to write a custom AppScript function in Google Sheets that will enable them to apply Large Language Models (LLMs) from OpenAI and Anthropic to their spreadsheet data.

By the end, attendees will be able to write a formula like =LLM(A1, “gpt-4o”, “Is this text about immigration?”), then drag it down to apply it to hundreds of rows at once. This will enable us to apply the astonishing natural language capabilities of LLMs en masse to cells within our spreadsheet.

Attendees will acquire the following skills:

- Using AppScript to write custom functions in Google Sheets

- Using LLMs via APIs

- Some basic LLM prompting techniques and tips

- Understanding when an LLM is likely to be reliable (when its output is based entirely on data within the spreadsheet) and when it is more likely to hallucinate (when its output draws on its own limited knowledge of the world)

Together at last: R and Python united in the Positron IDE
Saturday May 24, 2025 1:45pm - 3:00pm CEST
For years datajournalists have been forced to choose between learning R or Python in order to do data analysis with a scripted language. This meant the choice of IDE (integrated development environment – the app for writing and managing scripts and files) was always a  defining decision.

R users mostly turned to RStudio to maintain R and run scripts, make plots etc. Python users have had a variety of options – Google Colab, Jupyter, Anaconda etc to manage their scripts and projects.

Now there’s a program built to handle both languages in parallel (but not quite simultaneously!) - it's called Positron.

In this session we will introduce you to the Positron program. We will show you the interface, and how to get started with your usual coding language, before working through some scenarios where being able to move quickly from one language to the other is desirable. (And if you have examples of times when you’ve needed this facility, please bring them to this session)

You will ideally have some experience of R or Python, and some appetite for using the other language, perhaps even on deadline. If you want to follow along in the session, install Positron beforehand from https://positron.posit.co/

Solomon's investigation "Who Owns the media" mapped the media owned by the top oligarchs behind the biggest media conglomerates in Greece and, more importantly, the oligarchs' broader businesses. We identified 800 companies in sectors such as shipping, energy, sports, banking, and real estate, and searched business registries in more than 30 countries. The data were published in an interactive network diagram and a dedicated website.

This session will present the methodology for dealing with large amounts of data, finding companies of the same owner, and investigating registries that sometimes disclose ownership and others that do not. We will work on case studies of companies and deal with the possible obstacles and difficulties involved.

How to find stories in private finance data
Saturday May 24, 2025 1:45pm - 3:00pm CEST
Private finance data aggregators are a powerful - if often expensive - tool for understanding the investment and ownership structures of the funds or companies that are the subject of your investigation. With the right approach, they can also help generate stories by identifying suspicious or controversial flows of money. This sessions shows you how. We will share a case study from a recent series that revealed supposedly ethical public pension funds held investments in controversial businesses  - including tankers for Russian fossil fuels and crypto, all via opaque private equity intermediaries.

An investigative method to measure content on TikTok
Saturday May 24, 2025 3:30pm - 4:15pm CEST
In this session, we will show the methodology developed by The Guardian to gather and measure content published on TikTok during the UK election campaign. Using this methodology, we revealed how far-right Reform's leader, Nigel Farage, [outperformed all other parties and candidates](https://www.theguardian.com/politics/article/2024/jun/26/nigel-farage-outperforms-all-other-uk-parties-and-candidates-on-tiktok) on the platform. We also exposed the [political content shared during the campaign](https://www.theguardian.com/politics/article/2024/jul/04/ukpolitics-how-the-2024-general-election-has-played-out-on-tiktok) aimed at young audiences.
During the session, we will also show how to set up accounts that are located in countries different to the one where the reporting team is based. We will also show the scraper to automatically gather content associated with particular hashtags at various times over several days. TikTok is relatively hostile to scrapers, forcing us to resort to advanced scraping techniques including residential proxies. We will also show how we identify the main content creators, using some metrics from TikTok as well as the number of videos recommended by the algorithm, and how we used the algorithm to manually find more related videos - and therefore Tiktokkers - similar to those we were investigating.

How to use data to investigate Big Pharma — secret medicine prices, industry funding and tax havens
Saturday May 24, 2025 3:30pm - 4:45pm CEST
Europe's pharmaceutical industry is notoriously opaque – and powerful. Big Pharma doesn't want us to know how they determine the prices of the medicines they market, where they store their profits or to whom they hand out millions in funding. The Investigate Europe's investigation Deadly Prices revealed that millions of Europeans lack access to medicines that save or prolong lives in other European countries, and in six EU countries one in four of 32 important medicines analysed is missing, often because they are priced out of reach. This presentation will share tips and techniques on how to investigate Big Pharma – and be transparent about what still remains hidden. From using company and national data that can reveal the true costs of critical medicines to finding public disclosure data that shows who and where the industry's millions go, we will help you with ideas and case studies on how to scrutinise Europe's secretive pharmaceutical world.

The Investigative Commons - how to share structured data, document collections and build knowledge collaboratively
Saturday May 24, 2025 3:30pm - 4:45pm CEST
The Investigative Commons is a collaboratively maintained repository of datasets and document archives useful for investigative reporting to ensure long-term access to evidence.

Currently, datasets (evidence) for investigative journalism are maintained by several media organizations and journalism networks, which can’t be reliable long-term partners for data accessibility due to changing priorities of newsrooms and the specific funding situation of investigative journalism. Even further, organizations involved in investigative research and publishing stories should not even take the burden off providing long-term equal access to evidence data (though it’s appreciated if they can afford it for some time).

We want to launch this new project and show the different available datasets and how everyone can use them. Further, we will explain how to contribute to this open and community-driven project and discuss further plans and ideas from the community.

Maps-Not-Maps: visualising qualitative data in investigative journalism
Saturday May 24, 2025 3:30pm - 4:45pm CEST
This session explores the powerful potential of visualising qualitative data – interviews, archives, testimonies, police reports, and more – within investigative journalism. We’ll delve into how these rich, often non-georeferenced sources can be transformed into compelling maps, diagrams, and visual narratives, offering unique insights into complex stories.

Moving beyond traditional hard data visualisation, this approach can reveal hidden patterns and connections within qualitative information and illuminate the human dimension of investigations, adding depth and clarity to narratives that might otherwise remain opaque. We’ll also examine how combining qualitative visualisation with hard data, such as satellite analysis, can strengthen the accuracy and impact of investigative reporting.

During this session, Federico Caruso (editorial coordinator, European Data Journalism Network) and Riccardo Pravettoni (journalist cartographer, Le Monde) will explain the mechanisms and choices involved in creating some of Le Monde’s most impactful visual stories, drawing from examples such as the Mazan trial, Saydnaya prison, and events in Lebanon and Gaza. We’ll examine how they analyse information, select sources, and craft the aesthetic look of these formats.

No prior knowledge or expertise is required to attend. You also won’t need to bring any specific materials.

You will leave this session with a better understanding on how to:
- Identify and extract valuable information from qualitative sources
- Apply various visualisation techniques to represent this data effectively
- Combine qualitative and quantitative data for stronger investigative narratives
- Appreciate the importance of scale and aesthetic choices in visual storytelling
- Gain a practical understanding of the processes involved in creating compelling visual journalism

Taking data to the people: building up and using databases as investigative storytelling
Saturday May 24, 2025 3:30pm - 4:45pm CEST
Most investigative journalists have by now become used to getting data and building up datasets and databases as part of their research. And that's also most often the case in cross-border collaborative investigations, where data is normally the common language of the journalists and media participating (as well as English).

What is less common is then publishing or making those databases accessible, and using them as part of the storytelling when presenting and disseminating our investigations. And that's a shame, because the databases behind our research can provide us with an opportunity to reach and engage our audiences in interesting and novel ways.

In this session, two [OR three] investigative journalists, from two very different contexts, Serbia and Switzerland, will present how they went about building up or compiling complex databases as part of their investigations, and then making those databases publicly available and accessible to their audiences, and using the databases as part of their storytelling.

Come to this session to get inspired and learn how you can compile and use databases, not only as part of your research, but also making them part of the story to increase the reach and engagement of your investigations.

How can can journalists use metaprompting to let AI build system instructions for assistants that empower their investigations? Through examples of iterative metaprompting Rune Ytreberg will show you how to master the art of efficient prompting to empower your investigations. You can use metaprompting to build AI assistants that unlock the black box of AI.

After attending this session you will be able to use advanced prompting techniques (meta-prompting) to use a large language model (LLM) to make system instructions. These advanced prompts are detailed instructions that customizes AI assistants to support investigations. They are amomg others used in Open AI and Anthropic projects, and RAG platforms like Kotaemon or Anything LLM.

You can attend this session without any prior knowledge, but you would need some basic knowledge of prompting using tools like Chat GPT, Claude or similar, if you would like to do this as a hands on session.

Automated migration control: tracking dystopian technology and funding across the EU
Sunday May 25, 2025 9:30am - 10:45am CEST
The EU is increasingly dedicating resources and funding to developing technologies aimed at tracking migration flows, using biometric and other sensitive data, and monitoring borders with dystopian automated systems. These systems often target vulnerable groups, such as migrants, who are surveilled and exploited as data subjects without their consent.

While desk research provides a broad overview of funding flows, only firsthand investigations along the Mediterranean and Atlantic borders have enabled us to fully grasp how migration control is being transformed by surveillance and automation. On-the-ground journalistic investigations in Greece, Spain and Italy have revealed that such investments are frequently squandered on automated systems that either fail to function properly or are poorly implemented, resulting in millions of euros wasted. Instead of safeguarding migrants' lives, these technologies often place them at greater risk.

Join this session to learn how to conduct fieldwork research and gather primary-source information on the intersection of migration and technology. Little technical background is required to report on this issue, as its societal impact is immense. We will share our findings and demonstrate how to assess this critical topic avoiding EU hype reflected in money flows, public tenders, pressnotes, etc. while contrasting it with on the ground information.

Is my house at risk of flooding? : Using cadastral data to track buildings in flood-prone zones of the Mediterranean (and beyond)
Sunday May 25, 2025 11:15am - 12:30pm CEST
In this session, we'll explore the methodology behind Newtral's data-driven investigation of flood-prone buildings and areas in Spain, which allowed the data team to find that at least 200,000 buildings in the country are vulnerable to flooding. The investigation didn't only reply on traditional soil or urbanistic studies to identify flood-prone areas, but also used the information from Spain's National Cadastral to gather the data, city by city and street by street, of all the buildings constructed in vulnerable or hazardous zones. We will share the model that can be replicable and/or scalable to other European countries, particularly those in the Mediterranean region. Through this session, attendees will learn how to source, process, and visualize cartographic data of urban typology to identify threatened areas. This session is suitable for beginners. Attendees should Python installed, along with a code editor like Visual Studio Code. No coding knowledge is necessary - the code will be shared with you, and you can just follow along. If you use Windows, please install Ubuntu (on Mac, this is not necessary).
