< Back Adelaida Afilipoaie Postdoctoral Researcher adelaida.afilipoaie@vub.be I am a senior researcher in the field of media policy, with an affinity for electronic communications networks and services, and online platforms. I am part of the Brussels-based imec-SMIT, Vrije Universiteit Brussel research group, more specifically part of the Media Economics and Policy Unit. In 2016 I graduated from my BA. in Media Studies and Television in the United Kingdom. After gaining theoretical knowledge and hands-on production experience in the media industry, I decided to pursue a MSc. in Communication Studies at the VUB in Brussels from which I graduated in 2018. Right after graduating I started working at imec-SMIT, Vrije Universiteit Brussel, where, by combining economic platform theories and media policy research, I conducted my PhD on the regulatory frameworks at the EU and Member States level, and their ability to address the online platform power concerns, which I finalized in 2023. Currently, I am conducting postdoctoral research for several projects (Fair MusE, ALGEPI and GMICP). Considering the domination of online platforms and their algorithms, these projects tackle the various concerns of the European music ecosystem, the impact of algorithmic gatekeepers on individuals’ epistemic welfare and the media markets concentration trends. When I am not involved in research, I am a guest lecturer for the Digital Media in Europe Master’s programme at the VUB and I act as a master’s thesis supervisor. During my time as a PhD candidate, I acted as a Teaching Assistant for the MSc. course European Media Markets and facilitated several workshops part of the now discontinued Postgraduate in Media Economics programme at the VUB (2018-2020). I have experience with European projects as I was a contributor to the SMART 2018/0066 study on the implementation of the new provisions in the revised Audiovisual Media Services Directive (AVMSD) and CNECT/2020/OP/0099 study on the Media Plurality and Diversity Online, both funded by the European Commission’s DG CNECT.

< Back Tim Raats Associate Professor tim.raats@vub.be Most of us have grown up with public service broadcasting and linear television as the focal point for news, entertainment and TV drama. While television and public broadcasting still exist today, and still take up crucial positions in the European media landscape, the entire audio-visual constellation has – and is – changing at a rapid pace. My research interests lie on the crossroads of these changes and continuities. In my work, I combine policy research, production studies and media economics to analyse shifts in small audio-visual ecosystems. My expertise areas are public broadcasting policies and strategies on the on the one hand, (with specific attention for public broadcasting partnerships) and the sustainability of television industries in small markets, where I specialized in financing and production of TV drama. I currently lecture various media policy courses (political economy of the creative industries, media policy, EU Media Policy) at the Communication Studies Department of the Vrije Universiteit Brussel. I obtained a PhD in 2014 on the role and position of public service media in a networked society. As a senior researcher at imec-SMIT, I have been involved in contract research for various stakeholders (including VRT, the Flemish Sector Council), either as researcher, lead researcher or supervisor. Recent projects I was involved in include MeCETES (2014-2016) which analysed patterns of film and TV distribution in Europe, a 2016 stakeholder evaluation of the Flemish Game Fund, and a study examining the effectiveness of support mechanisms for television in Flanders (2016-2017) (in collaboration with Econopolis).

< Back 4 Nov 2024 In a new policy brief and webinar, we present the findings of research on motivations of Flemish viewers ⇩ ENGLISH BELOW ⇩ Tijdens een webinar op 31 oktober presenteerde het Proeftuin Project nieuwe inzichten over de streaminggewoonten en voorkeuren van Vlaamse kijkers. Dit zijn de vijf belangrijkste conclusies: 1. Kijken blijft een collectieve activiteit Streaming biedt gepersonaliseerde aanbevelingen, maar kijkgedrag vertoont nog steeds sterke overeenkomsten met het traditionele, lineaire kijkpatroon. Keuzes worden vaak beïnvloed door sociale omgevingen, en samen kijken blijft een waardevolle culturele activiteit. Het ‘watercooler-effect’, waarbij populaire shows gesprekstof opleveren, blijft relevant, zowel voor internationale hits als lokale titels. 2. Lokale platformen lopen achter met personalisatie, maar voldoen aan verwachtingen Internationale platformen zijn sterk in personalisatie, terwijl Vlaamse kijkers vaak al weten wat ze willen zien op lokale platforms zoals VRT MAX en VTM GO. Hoewel deze platformen geavanceerde aanbevelingssystemen missen, slagen ze erin om te voldoen aan de vraag naar specifieke lokale content. De belangrijkste uitdaging blijft het uitbreiden van de catalogus en de gebruiksvriendelijkheid verbeteren. 3. Vlaamse kijkers waarderen lokale content Lokale platformen zijn de voorkeurskeuze voor Vlaamse kijkers die op zoek zijn naar regionale shows, terwijl grote streamingdiensten zoals Netflix over het algemeen worden geassocieerd met internationale content. Deze waardering voor lokale content geeft platformen zoals VRT MAX en Streamz de kans om zich te onderscheiden, vooral voor kijkers die regionale verhalen belangrijk vinden. 4. Streaming en bioscoop bezoek: Complementaire ervaringen Vlaamse kijkers zien streaming en bioscoopbezoek als aanvullend op elkaar. Degenen die veel streamen, gaan ook vaak naar de bioscoop, vooral vanwege de gedeelde ervaring. Hoewel de prijs voor sommigen een drempel blijft, blijft de bioscoop aantrekkelijk vanwege de unieke sociale sfeer. 5. Lokale content leeft, maar internationale content domineert Vlaamse kijkers associëren lokale platformen sterk met regionale content, maar hun kijkgedrag op grote platformen neigt naar internationale series en films. Deze voorkeur voor globaal aanbod vormt het streaminggedrag, maar lokale platformen blijven inspelen op de vraag naar binnenlandse verhalen en ervaringen. Voor een diepgaandere analyse, bekijk de volledige policybrief op de SMIT-website . ___________________________________ During a webinar on October 31, the Proeftuin Project revealed fresh insights into the habits and preferences of Flemish streaming audiences. Here are the five main takeaways: 1. Watching together remains Streaming may allow for individual recommendations, but watching habits still mirror traditional, linear viewing. Choices are often influenced by social settings, and shared viewing remains a strong cultural activity. The “watercooler effect,” where popular shows spark conversations, is still alive, with both international hits and local titles playing a role. 2. Local platforms lag in personalization but meet viewer expectations While international platforms excel at personalization, Flemish viewers often know exactly what they want to watch on local platforms like VRT MAX and VTM GO. These platforms lack sophisticated recommendation systems, yet they succeed in catering to viewers' demands for specific local content. The main challenge remains expanding their catalog while enhancing usability. 3. Flemish viewers value local content Local platforms are the preferred choice for Flemish audiences seeking regional shows, while major streaming services like Netflix are generally associated with international content. This appreciation for local content allows platforms such as VRT MAX and Streamz to distinguish themselves, particularly for viewers who prioritize regional storytelling. 4. Streaming and cinema are complementary experiences Flemish viewers see streaming and cinema as complementary. Those who stream frequently also tend to visit cinemas, mainly for the shared experience. While price remains a deterrent for some, cinemas remain attractive for their unique social environment. 5. Local content thrives, but international content dominates While Flemish audiences strongly associate local platforms with regional content, their actual viewing behavior on major platforms leans towards international series and films. This preference for global content shapes streaming behavior, yet local platforms continue to meet the demand for domestic stories and experiences.

< 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 Understanding user preferences in recommender systems: A systematic review with a user-centric perspective in the audiovisual domain Li, D., Smets, A., & Ranaivoson, H. (2026). Understanding user preferences in recommender systems: A systematic review with a user-centric perspective in the audiovisual domain. International Journal of Human-Computer Studies , 103741. User preference is central to the design and effectiveness of recommender systems (RS), as its satisfaction influences both user experience and platform success. However, the concept of user preference is inherently complex, and existing knowledge remains diverse and fragmented, lacking a synthesis that considers users’ multiple and evolving needs. Adopting a user-centric perspective, this study systematically reviews 135 RS papers focused on how user preferences are defined and operationalized in the audiovisual (AV) domain. Grounded in theories of multi-attribute utility and bounded rationality, this review focuses on key dimensions related to the conceptualization and application of user preferences in RS studies. We develop a typology to categorize the main issues and methodological approaches and identify prevailing trends and research gaps across these dimensions. Our findings reveal that: (1) user preference definitions are frequently absent, with few studies offering explicit conceptualizations. (2) user participation in preference elicitation is limited, with most studies relying on offline datasets and prioritizing content relevance metrics over user experience; (3) User attributes, such as demographics and personality traits are underrepresented compared to item attributes like content features, leading to overspecified models and reduced interpretability; and (4) interest in temporal and contextual preference dynamics is growing, although stability remains crucial for consistent recommendations. These findings indicate critical shortcomings in understanding and operationalizing user preferences from a user-centric perspective. We emphasize the need for greater integration of insights from psychology and behavioral studies to ensure that RS design aligns with users’ intrinsic, evolving, and long-term needs.

< 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 FIRE: A Modular Framework for Prototyping and Evaluating Interactive Recommender Explanations Ulysse Maes, Cedric Waterschoot, Francesco Barile, and Nava Tintarev. 2026. FIRE: A Modular Framework for Prototyping and Evaluating Interactive Recommender Explanations. In Proceedings of the 34th ACM Conference on User Modeling, Adaptation and Personalization (UMAP '26). Association for Computing Machinery, New York, NY, USA, 484–486. Explanations in recommender systems are important for enhancing transparency, trust, and system understanding. However, as research interest in interactive and chat-based explanations grows, the absence of standardized, reusable interface components limits their systematic evaluation. We introduce the Framework for Interactive Recommender Explanations (FIRE) to bridge this gap. FIRE provides an open-source library of modular explanation styles with varying levels of interactivity — spanning from static lists and draggable charts to conversational agents. To test these modalities in online user studies, FIRE integrates a supporting serverless experiment engine equipped with dynamic routing, crowdsourcing integration, and complete interaction logging. Currently configured for group recommenders but built for broader applicability, FIRE helps to standardize the evaluation of the explanation layer, thereby driving reproducible experimental design.

< Back 15 Sept 2023 Exploring Power Dynamics in Digital Platform Markets: A Pragmatic Approach to Normative Recommender Systems We are excited to share that our research team has contributed a paper to the first workshop on Normative Design and Evaluation of Recommender Systems (NORMalize), co-located with the 17th ACM Conference on Recommender Systems in Singapore. Our paper, titled "Towards a Pragmatic Approach for studying Normative Recommender Systems: exploring Power Dynamics in Digital Platform Markets" examines two key economic dynamics prevalent in digital media markets that challenge the development of normative RSs. The first hurdle focuses on the susceptibility of digital platforms to lock-in and monopolization due to network effects, skewing the power balance towards system providers. The second hurdle delves into the "attention economy" and the engagement-centric logic in RS design. This logic, while successful in boosting engagement, might compete with explicit or long-term user objectives We illustrate the real-world significance of these dynamic with insights from the domains of video-on-demand and news media. Furthermore, by offering policy recommendations we wish to address the normative challenges that arise in RS design. PhD researcher Hanne Vandenbroucke will be presenting this paper during the NORMalize workshop on Tuesday, September 19. Previous Next New publication: NORMalize Workshop (@ RecSys23)

< Back 15 Jul 2025 Commissioned by the Flemish Minister of Media, this research report investigates findability, discoverability, and due prominence for audiovisual and auditive media services. We’re pleased to announce that the study conducted by Prof. Dr. Tim Raats , Dr. Adelaida Afilipoaie , Pieter Van der Elst , and Noëmie Forest for the Flemish Minister of Media and the Department of Culture, Youth and Media has now been officially published. The report, titled Study on appropriate prominence, visibility and findability for audiovisual and auditive media services of general interest in Flanders , is now available via the Department’s website. 📄 Read the full study (in Dutch) here: 👉 https://www.vlaanderen.be/publicaties/studie-omtrent-passende-aandacht-zichtbaarheid-en-vindbaarheid-voor-audiovisuele-en-auditieve-mediadiensten-van-algemeen-belang-in-vlaanderen The study addresses a pressing policy question: How can we ensure that audiovisual and audio media services of general interest remain findable, discoverable, and appropriately prominent in the digital media environment — and what additional policy measures might be needed in Flanders to achieve this? As part of our academic work on media policy and platform regulation, we developed this research as a contribution to the Flemish media policy agenda. The report: Maps the current Flemish landscape on the matter Compares with international practices and emerging regulatory approaches across Europe And formulates recommendations for a future-proof policy framework . We’re also pleased to see that the report has already had direct policy impact : it served as a reference work for the Department in drafting new plans around prominence and findability, which were approved by the Flemish Government in early July . These plans make Flanders one of the first smaller media markets in the EU to introduce a legal framework explicitly addressing prominence for media services of general interest — a notable development in the implementation of Article 7a of the EU Audiovisual Media Services Directive (AVMSD). This project reflects the broader media policy research of our SRP Media team at imec-SMIT. An academic publication on the topic of due prominence for media services of general interest — authored by Pieter, Adelaida, and Tim as part of Pieter’s ongoing PhD research on the platformization of public service media — is also forthcoming.

< Back 21 Jul 2025 Aina's recap of the AI Summer School at KU Leuven Aina Errando started the summer of 2025 with the AI Summer School at KU Leuven , organised by the Centre for IT & IP Law (CiTiP). As a PhD researcher within the ALGEPI project, she was selected to join the 5th edition of this summer school. The programme brought together an interdisciplinary and international cohort of researchers, legal scholars, and professionals to explore some of the most pressing regulatory and ethical challenges in the field of artificial intelligence (AI). Over two intensive weeks , participants engaged with a broad spectrum of topics, including: The EU AI Act, Digital Services Act (DSA), and Digital Markets Act (DMA) The Council of Europe’s Framework Convention on AI, Human Rights, Democracy and the Rule of Law The OECD AI Principles and UNESCO’s Recommendation on the Ethics of AI Critical discussions on AI auditing, transparency, fairness, and accountability The sessions were led by renowned scholars and practitioners , and their contributions created an intellectually rich and challenging environment that encouraged participants to critically reflect on the intersections between law, ethics, and AI innovation . During the programme, Aina had the opportunity to present her work-in-progress titled “Regulating the News(rooms): Between AI Policies and Editorial Realities in Europe” , developed as part of the ALGEPI project . Furthermore, one of the programme’s highlights was a gamified group challenge , where participants were assigned roles in a fictional regulatory debate. Aina and her team were tasked with unconditionally defending regulatory sandboxes under the AI Act. The AI Summer School came at a particularly relevant time, as institutions across Europe are working on implementing the AI Act, as well as other digital regulations and policies. The programme offered an opportunity to gain practical insights into how regulation is interpreted, contested, and applied across different sectors and jurisdictions. Together with other summer school attendees, Aina wrote a blog post on the AI regulatory Sandboxes established under the EU AI Act. Would you like to know more about it?

< Back Public Service Media and Platformization Pieter Van der Elst PhD Researcher This part of the SRP research project aims to develop in-depth knowledge on how an increasingly algorithmized media industry compels European Public Service Media (PSM) to alter their operational and value-related strategies. During a time period of 4 years, we will scrutinize how PSM’s part in the media value chain is affected and what that means for the company, the content and the end-user. A first phase of the research focuses on the organizational side of PSM. More specifically, we concentrate on the case of Flemish public broadcaster VRT and how they are operationalizing a digital and user-first approach in their digital audio strategy. Complementary analysis of the decision-making behind this organizational shift will be key to developing a thorough understanding of what it means for a public legacy media player to adapt to the ever-changing industry it operates in. In later stages of the project, our focus will shift towards what said transition implies for PSM on the levels of content production, distribution and the societal core values imbued. This part of the research will also broaden our scope geographically by including scrutiny of other European PSM organizations and how their methods compare to one another. Examinations of audience perspectives will conclude our research journey and provide us with indispensable insights on the topic. Through this research programme we aim to consolidate our understandings on algorithm-driven media operations and media-economics and media policy oriented PSM-research, not only serve the academic community, but also to provide small market PSM-organizations with tools to better understand and integrate algorithms, and assist policymakers in developing ways of regulating and measuring the impact of algorithms on media output and audience reach.
