< 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 Piecing the puzzle of VOD offerings: A comparison of eight US and local services in Flanders Iordache, C., Raats, T., Pakvis, M., & Asmar, A. (2023). Piecing the puzzle of VOD offerings: A comparison of eight US and local services in Flanders. Journal of Digital Media and Policy , 14 (3), 357 - 376. https://doi.org/10.1386/jdmp_00134_1 The study conducts a catalogue analysis that zooms in on the small market of Flanders (Belgium), and the content strategies of the eight most popular local and US-based players in the market. Through the comparative analysis, we investigate three main directions. First, we analyse the similarities and differences in the catalogue offerings of US and local video-on-demand (VoD) services. Second, we delve into the strategies of local players as they compete with US streamers and other legacy players. Third, we analyse the share and the characteristics of the Flemish titles on offer. The data was collected in the spring of 2022 and consists of 13,500 title entries. The findings point to a set of complex market dynamics. Local services and US-based players are competing and collaborating to create a jigsaw puzzle of on-demand offerings, through various strategies of complacency, resistance, differentiation and diversification/mimicry.

< Back Exploring Ethical and Regulatory Challenges of AI Integration in European Union Newsrooms Lefèvre, B., Errando, A., Afilipoaie, A., Ranaivoson, H., & Wiart, L. (2025). Exploring ethical and regulatory challenges of AI integration in European Union newsrooms. Media Studies , 16 (31), 31-55. Artificial Intelligence (AI) has significantly reshaped the news media landscape in the fast-evolving digital ecosystem. While recent legislative measures and industry self-regulation initiatives have emerged to address AI’s implications, the ethical challenges associated with its adoption in European Union (EU) newsrooms and the ways news media organisations navigate regulatory frameworks and internal initiatives remain underexplored. This study aims to bridge this gap by examining the conditions under which AI tools are integrated into media organisations from both organisational and regulatory perspectives. Drawing on an analysis of 30 key documents and 41 in-depth interviews with media professionals and regulatory experts across three EU markets, the study uncovers key findings: a limited discourse on AI use in media organisations, significant disparities in AI implementation practices, and an absence of clear, actionable regulatory guidelines for addressing considerations in AI-driven news content.

< Back Looking back at RecSys 2024 23 Oct 2024 Sharing our reflections on the ACM RecSys Conference 2024 Some researchers of the SRP Media team recently attended the 18th ACM Conference on Recommender Systems (RecSys 2024) in Bari, Italy. Known for its stunning coastline and sunny weather, Bari provided the perfect backdrop for a gathering of both academic and industry experts in recommender systems. Beyond indulging in the delicious Italian cuisine and navigating the city’s chaotic traffic, our team traveled to Bari to share our latest research, gain insights from the inspiring talks, and engage with the Recsys community. SRP Media's Contributions at RecSys 2024 A previous blog post already summarizes all of the SRP Media team's contributions to the conference. Annelien and Lien each gave a learning session at the RecSys Summer School, which took place the week before the conference. Ulysse attended the Summer School and then stayed another week in beautiful Bari to present a demo poster at the conference. During the conference, Brett participated in the doctoral symposium, where he presented his initial findings and received valuable feedback from leading experts. In addition, there was also a poster for Hanne and Annelien's paper which got shortlisted for the Best Short Paper Award! The RecSys Summer School: Gaining Insights Although RecSys 2024 officially kicked off on October 14th, some of our team members arrived in Bari a week early to attend the ACM Europe School on Recommender Systems. On the program there was Lien Michiels 's lecture on Best Practices for Offline Evaluation and Annelien Smets ' course on Digital Economics and Recommender Systems . Their insights offered a refreshing perspective amidst the buzz around transformer-based algorithms. Ulysse, as a participant in the Summer School, had the chance to connect with fellow researchers from around the world, fostering an environment of collaboration and learning. The Main Conference: Workshops, Presentations, and Keynotes The RecSys conference consists of two parts: on Monday and Friday, a series of workshops and presentations took place at the Politecnico University of Bari. From Tuesday to Thursday, the main track continues with an extensive program of lectures, presentations and posters at the magnificent Teatro Petruzzelli. Some of our highlights: Ulysse's highlights For Ulysse, one of the standout moments was the CARS workshop led by Dr. Rishabh Mehrotra from Sourcegraph. Drawing on his experience at Spotify, Dr. Mehrotra presented a thorough analysis of eight real-world recommendation challenges, offering invaluable insights into the practical applications of recommendation systems. Ulysse also appreciated a keynote from Mounia Lalmas, also from Spotify, as well as events like the Women in RecSys session, the Normalize workshop, and Netflix’s “Raising a Recommender System”—although his duties as a student volunteer required him to follow these online. Brett's reflections Brett's experience at the doctoral symposium was the outstanding highlight of the week. Thanks to valuable feedback from experts such as Julia Neidhardt, Markus Zanger and Bart Knijnenburg, Brett gained new clarity on his PhD project, particularly his development of the "Serendiptionnaire" a tool designed to evaluate how recommender systems promote serendipity. Throughout the main track, Brett found himself both impressed and challenged by the industry presence. While captivated by the venue and delighted by the food, he noted a strong focus on technical issues, which sometimes overshadowed a more human-centered approach. Mark Riedl’s keynote resonated with this perspective, particularly the idea that recommender systems should enhance user agency. Workshops like RecSoGood, AltRec , and the POPROX project emphasizing the importance of considering the societal implications of research on recommender system. Hanne’s first RecSys Attending the RecSys Conference in person for the first time was an exciting and enriching experience. The conference brings together researchers and industry practitioners from a wide range of sectors, creating a vibrant and open-minded community. The empowerment of women in this traditionally male-dominated field, with the Women in RecSys breakfast and session is very valuable to facilitate connections. Her own contribution, a short paper titled “It’s (not) all about that CTR: A Multi-stakeholder Perspective on News Recommender Metrics” was shortlisted for the Best Short Paper award. This nomination, together with the encouraging feedback on the poster, is a testament to the importance of interdisciplinary approaches in recommender system research. The need for bridging the gap between academia and industry echoed throughout the week. Final Thoughts: A Rich Exchange of Ideas and Inspiration RecSys 2024 in Bari offered not only an incredible learning experience but also an opportunity to engage with great minds in the Recsys field. From insightful workshops and keynotes to helpful feedback and new connections, our team left the conference feeling motivated and inspired. As we look ahead, the key takeaway is clear: recommender systems must evolve beyond technical optimization. The importance of fostering user agency, promoting social sciences in the research on recommenders, and bridging the gap between academia and industry applications is more pressing than ever.

< Back It’s (Not) All About That CTR: a Multi-Stakeholder Perspective on News Recommender Metrics Vandenbroucke, H., & Smets, A. (2024). It’s (Not) All About That CTR: a Multi-Stakeholder Perspective on News Recommender Metrics. In Proceedings of the 18th ACM Conference on Recommender Systems. Recommender systems are increasingly used by news media organizations. Existing literature examines various aspects of news recommender systems (NRS) from a computational, user-centric, or normative perspective. Yet research advocates studying the complexities of real-world applications around NRS. Recently, a multi-stakeholder approach to NRS has been adopted, allowing to understand different stakeholder perspectives on NRS development and evaluation within the news organization. However, little research has been done on the different key performance indicators (KPIs) and metrics considered valuable by different stakeholders. Based on 11 interviews with professionals from two commercial news publishers, this paper demonstrates that stakeholders prioritize distinct KPIs and metrics related to the reach-engagement-conversion-retention funnel. The evaluation of NRS performance is often limited to short-term metrics like CTR, overlooking the multiplicity of stakeholders involved. Our findings reveal how different purposes, KPIs, and metrics are valued from the journalistic, commercial, and tech logic. In doing so, this paper contributes to the multi-stakeholder approach to NRS, advancing our understanding of the real-world complexity of NRS development and evaluation.

< Back Towards a Pragmatic Approach for studying Normative Recommender Systems Binst, B., Vandenbroucke, H., Li, D., Puskas, I., Van der Elst, P., & Smets, A. (Accepted/In press). Towards a Pragmatic Approach for studying Normative Recommender Systems: Exploring Power Dynamics in Digital Platform Markets. In Proceedings of the the First Workshop on Normative Design and Evaluation of Recommender Systems . Recommender systems (RSs) have become an integral part of digital platforms, helping users to navigate through the abundance of online content and services. This paper argues that the study of normative RSs should go beyond the mere conceptualization of normativity and examine the conditions and contextual factors that might foster normative RSs. RSs often operate within multisided markets, involving multiple stakeholders who influence and are influenced by the RS. Ideally, developers of RSs aim for value alignment among diverse stakeholders, fostering a win-win scenario. However, in practice, system providers hold more power over the design, often optimizing for their own objectives and neglecting the needs and values of other stakeholders. These imbalanced power dynamics in digital platform markets pose significant challenges to the design. This paper critically examines two key economic dynamics in digital media markets that challenge the development of normative RSs. The first hurdle describes the susceptibility of digital platform markets to lock-in and monopolization due to network effects, which skews the power balance in favor system. A second hurdle critically examines the pervasive \"attention economy\" and corresponding engagement-centric logic in the design of RSs that might diverge from explicit or long-term users' preferences despite the success in increasing engagement. To illustrate the importance of these dynamics in real-world RSs, we present how these hurdles manifest in the domains of video-on-demand and news media. In conclusion, this paper advocates for a more pragmatic approach to studying normative RSs by considering the two hurdles affecting the RS development in contemporary digital platform markets. Furthermore, it highlights the fruitfulness of this pragmatic approach by proposing policy recommendations to tackle normative challenges in RSs’ design.

< Back Integrating discoverability and prominence in video-on-demand consumption choices. A qualitative user study in Belgium Iordache, C., Loisen, J., & Van Audenhove, L. (2023). Integrating discoverability and prominence in video-on-demand consumption choices. A qualitative user study in Belgium. International Communication Gazette . https://doi.org/10.1177/17480485231191898 As video-on-demand services have taken a central position in audiovisual distribution in European markets, over-the-top viewing has become increasingly popular. This shift has heavily impacted consumption patterns and exposure diversity, as they are reshaped by non-linear distribution and technological affordances. This article aims to integrate debates on discoverability and prominence within wider research on video-on-demand consumption. It does so by widening the existing focus on the strategies deployed by video-on-demand services to capture users’ contexts and actions in the consumption decision-making process. The framework is based on exploratory qualitative research conducted in Belgium through a diary study and in-depth interviews and can contribute to future audience research on video-on-demand consumption choices. We find that users discover and choose audiovisual content to consume on demand through a combination of formal and informal factors. These are grouped into four thematic categories, namely technological affordances, perceived offering, external ‘nudges’, and process. Platforms Previous Read the article Next

< Back Welcome to the Metrics Jungle: Organizational Stakeholder Perspectives on Evaluation of News Recommender Systems in Industry Vandenbroucke, H., Michiels, L., & Smets, A. (2025). Welcome to the Metrics Jungle: Organizational Stakeholder Perspectives on evaluation of news recommender systems in industry. ACM Transactions on Recommender Systems, Highlights of RecSys ’24. https://doi.org/10.1145/3778173 News recommender systems (NRS) are increasingly implemented in news industry to enhance digital distribution, yet their development and evaluation are shaped by a complex interplay of organizational stakeholders with diverse objectives. This study investigates the real-world complexities of NRS implementation, considering the multitude of objectives on the NRS provider side by exploring how different stakeholder groups —from journalistic, commercial and tech logic— conceptualize NRS goals and assess their performance. Through 22 semi-structured expert interviews across four news organizations in Europe, we uncover a `jungle of metrics' where an overabundance of data insights does not necessarily lead to better decision-making. While traditional accuracy-based metrics like click-through rate (CTR) remain widely used, they fail to capture the broader strategic objectives that guide NRS adoption in industry. This paper identifies a critical gap between current academic evaluations of NRS and the business key performance indicators (KPIs) used in practice. Rather than evaluating NRS in isolation, stakeholders assess their contribution to overarching organizational goals, including reach, engagement, conversion, and retention. Our findings highlight the need for a more nuanced, multi-stakeholder approach to NRS evaluation that aligns with both business imperatives and journalistic values.
