< Back Workshop: Best Practices for Responsible News Recommender Design 24 Sept 2024 Our takeaways from the workshop part of the NWO-funded project "Rethinking news algorithms" On 23rd of September, Aina, Hanne, and Ulysse traveled to the Vrije Universiteit Amsterdam for the workshop "Best practices for responsible news recommender design," part of the NWO-funded project "Rethinking news algorithms". This one-day event aimed to foster collaboration between academia and industry, focusing on the ethical design of news recommender systems. Aina and Hanne presented initial insights from their systematic literature review that aims to uncover the organizational challenges, opportunities and social implications of news recommendation systems studied in Western media systems. One significant observation from the day highlighted the challenges in aligning all aspects of responsible news recommenders with diverse stakeholder goals. A key takeaway from our engaging conversations with colleagues and industry professionals is that diversity is frequently considered essential for the development of responsible recommenders, given the close relationship between the democratic function of news and media pluralism. The workshop enabled a cooperative sharing of ideas, fostering the co-creation of optimal strategies for responsible news algorithms. Attendees also pinpointed prospective research paths, underscoring the necessity of ongoing interdisciplinary collaboration to explore the societal implications of these systems. Previous Next

< Back Ciao from EMMA in Rome! 5 Jun 2025 Our presentations at the emma Conference 2025 On the first day of the EMMA Conference, Aina, Hanne, and Pieter joined over 20 other PhD students from all over Europe for the inspiring PhD Workshop. In small groups, under the guidance of an experienced researcher, each student got the opportunity to present some issues related to their PhD track, delving into theoretical frameworks, methodological approaches, data analysis, the writing process, and mental challenges such as dealing with impostor syndrome, The diversity of research themes and perspectives is of great value to our three PhD’ers as their starting the third year of their track. The workshop provided room for deepening, exchange, and building a valuable network of fellow researchers. And of course, there was also time to enjoy the sunshine, have an espresso, Aperol Spritz, and taste some Italian delicacies! 😋🇮🇹🍕 The second day of the EMMA Conference was dominated by fascinating presentations, including that of our colleague Aina , who presented her research with great flair. Aina’s ongoing research (as part of the ALGEPI project ) investigates how Europe’s AI regulatory frameworks—ranging from the EU’s AI Act and European Media Freedom Act (EMFA) to UNESCO and Council of Europe guidelines and national AI strategies in Belgium, France, and Spain—are or are not reshaping newsroom governance. The goal of this research is to explore the intersection between regulation and journalism more closely trying to understand how AI regulation translates into newsroom realities across European contexts. Through a two‐step approach of document analysis and interviews with legal experts, media managers, and practitioners, she discussed the impact of both hard and soft law in the journalistic context as well as media‐tailored AI policies that balance compliance with editorial independence. Next to Aina’s insights, it was inspiring to hear from other research themes and get some findings from other studies. After a strong day at the conference, we had a chance to explore beautiful Rome and do some sightseeing. The day ended in style with a delicious buffet full of authentic Italian dishes.🍝🍦 On day three of the EMMA Conference, it was Hanne and Pieter's turn to present their research. Together, they gave an engaging joint presentation in which they shared a comparative analysis of how decision-making around recommender systems for media distribution is shaped in commercial media companies and public broadcasters. Building upon the framework of Smets et al (2022), they investigate how the strategic perspective on integrating recommender systems differs in profit-oriented organizations and PSM. By integrating their individual case studies, they offered valuable insights into the divergent strategic goals, recommendation purposes, and the implications for the recommender system design. The take-away? There are some similar strategic goals and recommendation purposes for editorial, commercial, and technological stakeholders in both types of media organizations. Nevertheless, the interpretation of concepts such as 'relevant' and 'engagement' differs based on the organizational cultures in profit-driven and public service media. Slide of presentation: Preliminary findings on shared overarching strategic goals and recommendation purposes For those who cannot get enough of Pieter , he also gave an individual presentation afterwards in which he elaborated on his case study work on Flemish public broadcaster VRT. With a focus on the tensions and possible conflicts that arise between stakeholders in the decision-making processes that shape the recommender system development, his presentation elaborated on the stakeholders involved at PSM and the implications of (dis) alignment of their strategic interests. His VRT deep dive hinted at the merits of a stronger involvement of indirect stakeholders for public service delivery and provided learnings on how PSM could tackle future structural integrations of technological innovations, for example, that of generative AI, which was a heavily debated topic at this conference.

< Back Elevating Customer Value of media recommendations through Enhanced User Satisfaction and Development Media recommender systems often fall short by prioritizing behavioral data over user perception and experience, resulting in a disconnect between user preferences and actual consumption. The intricacy of multi-dimensional user preferences poses a challenge, compounded by an intention-behavior gap in high-quality media consumption. Unintentional content consumption can be exacerbated by recommendations geared towards engagement or revenue goals, potentially leading to misguided outcomes. Consequently, there is a critical need to refine recommender system designs from a user-centric perspective, accounting for nuanced preferences and intrinsic needs. This project takes a user-centric approach, delving into the role of media recommender systems in aligning user needs, preferences, and consumption. The overarching aim is to cultivate the generation of healthier, more beneficial recommendations, ultimately enriching user satisfaction and overall development.

< Back Not One News Recommender To Fit Them All: How Different Recommender Strategies Serve Various User Segments Vandenbroucke, H., Maes, U., Michiels, L., & Smets, A. (2025). Not One News Recommender To Fit Them All: How Different Recommender Strategies Serve Various User Segments. In 19th ACM Conference on Recommender Systems Proceedings . ACM. Many news recommender systems (NRS) adopt a one-recommender-for-all approach, overlooking that users engage with news in fundamentally different ways. In this work, we identify user clusters based on various engagement metrics that go beyond clicks by employing cluster analysis on two real-world datasets: EB-NeRD and Adressa. Next to that, we evaluate the performance of common rec-ommender strategies: popularity, collaborative filtering (EASE and ItemKNN), and a content-based model across these user clusters, which exhibit varying reading behaviors and information needs. Our findings show that different recommender strategies are effective to varying degrees depending on the user cluster. This study contributes to NRS research by providing a grounded clustering of users derived from real-world datasets and emphasizes the importance of user-centered evaluations for understanding how NRS strategies serve audiences with varying levels of news engagement.

< Back Platforms and Exposure Diversity: Towards a Framework to Assess Policies to Promote Exposure Diversity Ranaivoson, H. R., & Domazetovikj, N. (2023). Platforms and Exposure Diversity: Towards a Framework to Assess Policies to Promote Exposure Diversity. Media and Communication , 11 (2), 379-391. https://doi.org/10.17645/mac.v11i2.6401 The fragmentation of consumption and algorithms’ increasing impact on how content is recommended and displayed makes it even more important to analyse and promote exposure diversity, i.e., the extent to which audiences are exposed to, discover, and engage with diverse content. Although there is a growing literature addressing how to define media diversity in the context of the challenges posed by platformisation, this article translates the normative dimensions into a framework for operationalising exposure diversity into a tangible policy goal, taking into account datafication and its consequences in terms of increasing data requirements towards platforms. The main objective of this study is to analyse initiatives to assess exposure diversity in the platform era and to discuss how such assessment could be improved, particu‐ larly for policy initiatives. This involves addressing several challenges of existing approaches for the assessment of exposure diversity related to defining an appropriate frame of reference, determining the degree of diversity required, dealing with data transparency issues, and promoting user autonomy. To achieve this, we propose a framework for analysing initiatives aimed at assessing and promoting exposure to media diversity. Our framework is composed of four key features: measures (type of initiative), metrics (quantifying exposure diversity), data collection methods, and data requirements. We apply this framework to a set of 13 initiatives and find that policy initiatives can benefit from adopting metrics based on distances and experimenting with data collection methods.

< Back New policy brief: International versus local VOD 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 A glimpse into our work-in-progress 12 Feb 2024 Reflections on the research presented at Etmaal On Thursday 8th and Friday 9th February 2024, Hanne Vandenbroucke and Ulysse Maes attended the 26th edition of Etmaal van Communicatiewetenschap in Rotterdam. At this two-day conference, researchers from Communication Sciences in Belgium and The Netherlands unite to present their projects, get feedback from peers, and be inspired by the work of others. They were invited to present their work-in-progress during the Research Escalator. In this blogpost we highlight the key take-aways from their presentations. Multi-stakeholder approach to news personalization - Hanne Vandenbroucke What lies behind the "For you", "Read more" or "See also" sections on the website or mobile app of your favorite news brand? By conducting stakeholder interviews with professionals working in commercial news organizations operating in Flanders: DPG Media, Mediahuis and Mediafin; We aim to map the development and implementation of recommender systems. The key internal stakeholder groups involved in and impacted by news recommender systems are: (1) the newsroom, (2) the technical development, and (3) the commercial business unit. Based on the stakeholder interviews, we are able to build upon the multi-stakeholder framework of Smets et al. (2022) . The preliminary results give insights in the actual decision-making process for recommender development. News organisations started experimenting with a news recommender system on average 3 years ago. The initial process of trial and error had transformed into an ongoing cycle of adjusting the RS design. In practice both the newsroom and the business unit express their objectives, preconditions and concerns to the product owner who aligns the different perspectives and formulates a concrete set of goals. Next, the technology development team will operationalize these objectives into computational metrics and adjust the recommender system design. Performance data is continuously being collected and monitored. A feedback loop set up to communicate the results of the adjusted recommender to the product owner who – together with the data analytics team – derives insights from the data and report back to the business unit and newsrooms. Exploring the influence of misleading explanations on the perceived quality of recommender systems – Ulysse Maes Nowadays, recommender systems are everywhere: you find them on Amazon, on Netflix and Spotify, for example. These algorithmic curation systems help internet users to efficiently navigate through vast amounts of content. While holding clear advantages in terms of user experience, there are some limitations and normative concerns. One of these concerns stems from the limited transparency they provide. This may lead to distrust and frustration. Adding explanations may yield different results, which depend on your objectives. (Tintarev & Masthoff, 2007) suggest seven goals of explainable recommendations: effectiveness, efficiency, satisfaction, scrutability, transparency, trust, and persuasiveness. Note that maximizing for one goal might be beneficial for another (e.g. improving for scrutability- giving users the ability to change the outcomes to their liking- might improve satisfaction). However, optimizing for one goal might also harm other goals. This research specificially dives into the possible conflict between optimizing for persuasiveness and its effects on transparency and trust. By “optimizing for persuasiveness”, we mean creating compelling narratives to persuade users to consume recommended content. For example, when you buy a pair of jeans online, the shop can try to upsell by recommending some white t-shirts and explain the recommendations as “Style advice for the perfect shirt to wear on your new jeans.” A more neutral explanation could be: “Customers also bought.” Persuasion in itself is not problematic, but it might become problematic once it becomes misleading: hiding important information or even lying about the working of the system, or the drivers behind a decision. As explanations are often linked to a conception of transparency, both with end-users and academia, the mere presence of explanations can already lead to increased trust in the system. By crafting compelling but incorrect explanations, it might be possible to manipulate users into consuming certain content, while still giving them a feeling of agency. There are clearly some incentives to create misleading explanations. But do they work? Theory is still inconclusive. While some research mentions the effectiveness of personalized persuasion (Burtell & Woodside, 2023), others highlight the detrimental effects on long-term trust: would platforms really jeopardize this? Another argument against the effectiveness of misleading explanations is that the costs don’t outweigh the benefits – a critique sometimes formulated on explanations in general as well. The field of explainable AI recognizes the immense potential of Large Language Models (LLMs), such as ChatGPT, to generate personalized, dynamic explanations at scale. It has already been shown that these explanations can be more persuasive than human-generated texts. One of the reasons why we do not see LLM-generated explanations popping up everywhere, is because of their tendency to “hallucinate” - to make up plausible, but incorrect narratives. Previous Next

< Back Interface real estate: Amazon Prime and visibility politics van Es, K., & Iordache, C. (2025). Interface real estate: Amazon Prime and visibility politics. Critical Studies in Television , 0 (0). https://doi.org/10.1177/17496020251375211 This paper investigates how Amazon Prime Video’s interface design affects content visibility, specifically analysing the prioritisation of Prime-included versus third-party content. Using the Vignette tool on French accounts, we conducted a mixed-methods analysis of homepage structures, including row hierarchies and title heatmaps across multiple user profiles. We find that while Prime Video shares common strategies with other services (e.g. own content prioritisation and burying the continue watching button), it distinguishes itself with a uniquely dense landing page layout featuring a large number of thumbnails and content rows. This design reveals deeper commercial logics shaped by Amazon’s integrated retail model. Previous Read the article Next

< Back Catching the waves: The case of VRT's digital-first audio strategy Van der Elst, P., Iordache, C., & Raats, T. (2025). Catching the waves: The case of VRT’s digital-first audio strategy. European Journal of Communication . https://doi.org/10.1177/02673231251370877 European public service media (PSM) are increasingly embracing strategies that balance digital platform tactics and meeting the public remit. This article addresses how a small market PSM is repositioning itself in a media landscape dominated by global platforms, streaming services and legacy media adopting platformisation strategies. We examine platformisation at the Flemish broadcaster VRT through the lens of its digital audio strategy. The study combines document analysis and expert interviews. Results show a strategic shift towards more focus on user needs and habits; a branding strategy revolving around the VRT parent brand; a necessary yet precarious presence on third-party platforms; a legacy-driven content offering complemented by online-only commissioning; and a firm editorial grip on content curation. VRT's take on these strategic innovations highlights a series of key dilemmas for PSM to reconcile public remit delivery and competitiveness in a platformised media landscape.

< Back Challenges and requirements for implementing due prominence: aligning stakeholder interests in Flanders Van der Elst, P., Afilipoaie, A., & Raats, T. (2025). Challenges and requirements for implementing due prominence: aligning stakeholder interests in Flanders. Frontiers in Communication, 10. https://doi.org/10.3389/fcomm.2025.1569132 Since the introduction of Article 7a in the Audiovisual Media Services Directive (AVMSD), which enables Member States to impose measures that ensure prominence of general interest services on user interfaces, discussions within media policy on the need of these measures have increased markedly. In Member States such as Germany, France, Italy and Ireland, commitments were already imposed on players offering user interfaces to audiovisual—and in some cases also audio—media services and content of general interest. This article presents the findings of a study examining the desirability and feasibility of implementing due prominence measures in Flanders (Belgium). The research adopts a media policy analytical approach and examines the (i) positions of the different stakeholders on the desirability and feasibility of a revised prominence regime, (ii) the extent to which interests across different stakeholders can be aligned and (iii) the considerations governments need to take into account when developing due prominence measures in Member States. The research is based on a stakeholder consultation conducted with broadcasters, television distributors, streaming services and hardware manufacturers operating in the Flemish market. The research is complemented with interviews with representatives of different market actors. The study identifies considerable oppositional logics between broadcasters and hardware manufacturers and raises challenges in defining the scope of ‘general interest’, the addressees of prominence measures, contextual factors such as markets size and path-dependency in media policy, and the commensurability between different existing legal frameworks at the national and EU level. The authors argue for clearer, more explicit guidelines at the EU level regarding the interpretation of Article 7a. Stakeholders Previous Read the article Next
