< Back Understanding Algorithmic gatekeepers to promote Epistemic welfare ALGEPI Technological and economic developments have led to the availability of an overwhelming quantity of digital content. Therefore, it has become crucial, in particular for media content providers, to incorporate algorithmic gatekeepers, which filter, rank and recommend content. Are these algorithmic gatekeepers undermining media’s contribution to epistemic welfare? In ALGEPI, we start from the novel concept of epistemic welfare, defined as the individuals’ right to know and be exposed to trustworthy, independent and diverse information while respecting individual rights to their own data. By connecting legal, political, technological and sociocultural perspectives, we will develop a conceptual framework for epistemic welfare. This framework will allow us to understand the effects of algorithmic gatekeepers on epistemic welfare. The new interdisciplinary research program will build on multi-method empirical research applied to algorithmic gatekeepers. Thanks to the theoretical and empirical findings, we will be able to develop normative instruments to align algorithmic gatekeeping with epistemic welfare. Taking the novel concept of epistemic welfare as a starting point allows all project partners to embark on a joint, integrated exploration of the concept. This may lead to a paradigmatic shift in the conceptualization of the impact of algorithmic gatekeepers in media sectors, proposing to expand the notions of media pluralism and consumer welfare to epistemic welfare.

< Back Catalina Iordache Guest Professor catalina.iordache@vub.be Coming from an Eastern European background, my life completely changed in the early 1990’s when the colours and fast-moving images of cable TV reached our living room, and I experienced an instant fascination with film, television programmes and music videos. Through my studies, I became interested in the market forces behind audiovisual media and the cross-border flow of content. At SMIT, I have the opportunity to apply qualitative methods in investigating the production and distribution of content, as well as its consumption by diverse audiences. I have been working at imec-SMIT-VUB since 2014, where I obtained my PhD on the transnational flow of media content in the online environment in 2022. I am currently conducting postdoctoral research on the platformisation of Public Service Media (PSM) and am also a Guest Professor and co-titular of the course Media, Culture and Globalisation Theories, for the Digital Media in Europe Master’s programme at the VUB. During my time at SMIT, I have also conducted research on the topics of media literacy, digital literacy and e-inclusion, and acted as Teaching Assistant for the Bachelor in Social Sciences programme. Before joining academia, I worked as a project manager in the cultural field with a community arts organisation based in Edinburgh. I then moved to Brussels and followed the international MSc in Communication Studies at the VUB. I also hold a BA in International Relations, European Studies. Visit my research profile

< Back Serendipity Engine SBO We increasingly rely on algorithmically generated recommendations to navigate in both online and offline contexts: listening to music on streaming platforms, reading news online, or following recommendations about activities and events in your favorite city. These recommender systems help us dealing with the abundance of available information, but at the same time raise questions about their impact on individual citizens and society. Many advocate for designs for serendipity in recommenders, but what does this mean in practice? While serendipity is generally understood as a beneficial design principle ought to deliver societal value, putting it into practice still presents major challenges. The Serendipity Engine project sets out to address these challenges and support societal stakeholders in designing recommender systems to foster serendipity in public contexts.

< Back Talking about Stakeholder Perspectives at WMEMC 22 May 2025 Hanne presented her research on stakeholder alignment for news recommender system development Today at WMEMC, Hanne presented her work on what happens behind the scenes of news organizations that are developing in-house News Recommender Systems (NRS). Spoiler alert: it’s no smooth ride. As newsrooms explore the possibilities of algorithmic curation, it turns out there's a lot more involved than just building smart tech. The real challenge? Getting all organizational stakeholders on the same page: journalists, software developers, managers, and business units each have their own goals, logics, and some concerns or doubts about (personalized) news recommendations. That’s where Hanne's research comes in. By setting foot in large-scale commercial news organizations (in Belgium, the Netherlands, and Scandinavia) and speaking to different stakeholders. Those interviews allow to explore the intricate (and let's be honest, sometimes messy) process of getting all organizational stakeholders to cooperate and negotiate NRS. The result? Balancing on a tightrope while juggling goals, demands, and objections. 🔹 Balancing Act #1 : Aligning Stakeholders Different stakeholder groups - newsroom, commercial units, and tech development teams - hold different perspectives on the opportunities and risks of (personalized) recommendations. Opposing views and expectations might lead to tensions between departments, and different product owners (POs) are assigned the role of mediators. These POs are ambidextrous actors with knowledge, experience, and professional backgrounds, crossing the traditional stakeholder boundaries, which enables them to create a shared understanding, translate jargon and build bridges between distinct stakeholder groups. A multi-disciplinary, cross-functional team of different POs, each representing another stakeholder group, sits around the negotiation table, and they are in charge of the decision-making around NRS. 🔹 Balancing Act #2 : Exploration vs. Exploitation Organizations constantly have to decide: do we explore new features and test new capabilities, or do we focus on optimizing our current technologies for ROI? With limited resources, news organizations can’t do both at full speed, simultaneously. Therefore, the team of POs needs to decide on which actions should be undertaken and, in doing so, develop a strategic roadmap navigating the tricky waters of budget and time allocations, and find that sweet spot between experimentation and exploitation. Both balancing acts are intertwined, as good alignment between stakeholders facilitates how these trade-offs are made. And the decisions made about the strategic roadmap for NRS development, in turn, influence whether stakeholders stay aligned or drift apart. It’s a dynamic, ongoing dance. The big takeaway? We need better, smarter ways to manage the decision-making on AI innovation in newsrooms, whether that relates to NRS or generative AI. This study is a first step in that direction — and just the beginning of figuring out how to align perspectives, reduce friction, and get these powerful tools off the ground in ways that actually work. Because building a scalable and effective recommender system is hard. But getting different stakeholders to agree on what the NRS design such look like? That’s where the real challenge lies.

< Back We're in this together: a multi-stakeholder approach for news recommenders Smets, A., Hendrickx, J., & Ballon, P. (2022). We're in this together: a multi-stakeholder approach for news recommenders. Digital Journalism , 10 (10), 1813-1831. https://doi.org/10.1080/21670811.2021.2024079 News recommenders are attracting widespread interest in scholarly work. The current research paradigm, however, holds a narrow (mostly user-centered) perspective on the recommendation task. This makes it difficult to understand that their design is in fact the result of a negotiation process among multiple actors involved, such as editors, business executives, technologists and users. To remedy this, a multi-stakeholder recommendation paradigm has been suggested among recommender systems scholars. This work sets out to explore to what extent this paradigm is applicable to the particular context of news recommenders. We conducted 11 interviews with professionals from three leading media companies in Flanders (Belgium) and find that the development of news recommenders is indeed characterized by a negotiation process among multiple stakeholders. However, our results show that the initial multi-stakeholder framework is not adequately accommodating some of our findings, such as the existence of preconditions, the role of product owners, and the indirect involvement of particular stakeholders. Based on our analysis, we suggest an elaborated framework for multi-stakeholder news recommenders that can contribute to scholarship by providing a multi-sided perspective towards the understanding of news recommenders.

< Back Heritiana Ranaivoson Research Professor heritiana.renaud.ranaivoson@vub.be While digital technologies have been here for quite some time already, I am still amazed by the changes they keep triggering in the cultural and media industries and how they allow (or constrain) these industries to innovate. I am particularly interested in the impact these changes have on the diversity of the content these industries produce and recommend. And eventually the policies that are needed in this new environment. I analyse these changes using my background in industrial economics, business modelling and media policy, with a peculiar interest in combining quantitative and qualitative research. I obtained my PhD in Economics (Université Paris 1, Panthéon-Sorbonne) in 2008 on cultural diversity in the recording industry. I also studied Economics and Management at Ecole Normale Supérieure de Cachan (France). Since then, and notably since I joined imec-SMIT-VUB in 2010, I have led several research projects at international and national levels for the European Commission ( H2020 , study contracts ), the Unesco , Google , etc. I have published extensively in the fields of cultural and media diversity , media innovation , media policy, audiovisual platforms , and the economic impact of digital technologies on creative industries .

< Back Wendy Van den Broeck Associate professor wendy.van.den.broeck@vub.be As the world of media and television is ever changing, it’s something I’ll never grow tired of. My first research project was on interactive digital television and it is unbelievable how rapid the industry and the technology have evolved since. New services like time-shifted viewing, Netflix, personalised advertising and immersive media applications have entered our everyday lives. At the same time, these trends are often not as disruptive as expected. For example when iDTV was introduced, it was announced that broadcasters would disappear and the 30 second commercial would die a silent death. Users are often surprising in their habits and practices. On the one hand, old habits die hard and user patterns tend to change slowly. On the other hand, surprising or unexpected usage of technology can lead to fascinating new developments. That is why user research is my biggest passion. I like to interact with users and unravel their motivations and expectations. I really believe in our living lab approach that puts the user in the centre of the design and development process. By involving users from the very early stage of an innovation process, we can help to develop technological services and products that are really user-friendly and society proof. This also helps the media industry to face the different challenges and disruptions they have to cope with today. I am currently head of the Living Lab cluster at SMIT and assistant professor at the communications studies department of the Vrije Universiteit Brussel where I teach several international and national courses, most of them related to research methodology. My current research projects relate to personalised and immersive media and include the EU projects Immersia TV , CPN and HRadio. I joined SMIT in 2003, after completing a master in communication sciences (VUB-2002), and obtaining a postgraduate diploma in management and economics (VUB-Solvay-2003) and a teaching degree (VUB-2003). During my time at SMIT, I finished my PhD in communication sciences in 2010 entitled: “From analogue to digital: the silent (r)evolution? A qualitative study on the domestication of interactive digital television in Flanders”. Visit my research profile

< Back How Should We Measure Filter Bubbles? Michiels, L., Vannieuwenhuyze, J., Leysen, J., Verachtert, R., Smets, A., & Goethals, B. 2023. How Should We Measure Filter Bubbles? A Regression Model and Evidence for Online News. In Proceedings of the 17th ACM Conference on Recommender Systems. News media play an important role in democratic societies. Central to fulfilling this role is the premise that users should be exposed to diverse news. However, news recommender systems are gaining popularity on news websites, which has sparked concerns over filter bubbles. More specifically, editors, policy-makers and scholars are worried that these news recommender systems may expose users to less diverse content over time. To the best of our knowledge, this hypothesis has not been tested in a longitudinal observational study of real users that interact with a real news website. Such observational studies require the use of research methods that are robust and can account for the many covariates that may influence the diversity of recommendations at any given time. In this work, we propose an analysis model to study whether the variety of articles recommended to a user decreases over time in such an observational study design. Further, we present results from two case studies using aggregated and anonymized data that were collected by two western European news websites employing a collaborative filtering-based news recommender system to serve (personalized) recommendations to their users. Through these case studies we validate empirically that our modeling assumptions are sound and supported by the data, and that our model obtains more reliable and interpretable results than analysis methods used in prior empirical work on filter bubbles. Our case studies provide evidence of a small decrease in the topic variety of a user's recommendations in the first weeks after they sign up, but no evidence of a decrease in political variety.
