Sanne’s research explores diversity in recommender systems, particularly in the news domain, and its connection to democratic values and goals.\nWe dive into four of her papers, which focus on how diversity is conceptualized in news recommender systems. Sanne introduces us to five rank-aware divergence metrics for measuring normative diversity and explains why diversity evaluation shouldn’t be approached blindly—first, we need to clarify the underlying values. She also presents a normative framework for these metrics, linking them to different democratic theory perspectives. Beyond evaluation, we discuss how to optimize diversity in recommender systems and reflect on missed opportunities—such as the RecSys Challenge 2024, which could have gone beyond accuracy-chasing. Sanne also shares her recommendations for improving the challenge by incorporating objectives such as diversity.\n\nDuring our conversation, Sanne shares insights on effectively communicating recommender systems research to non-technical audiences. To wrap up, we explore ideas for fostering a more diverse RecSys research community, integrating perspectives from multiple disciplines.\nEnjoy this enriching episode of RECSPERTS - Recommender Systems Experts.\nDon't forget to follow the podcast and please leave a review\nLinks from the Episode:\nSanne Vrijenhoek on LinkedIn\nInformfully\nMIND: MIcrosoft News Dataset\nRecSys Challenge 2024\nNORMalize 2023: The First Workshop on the Normative Design and Evaluation of Recommender Systems\nNORMalize 2024: The Second Workshop on the Normative Design and Evaluation of Recommender Systems\nAltRecSys 2024: The AltRecSys Workshop on Alternative, Unexpected, and Critical Ideas in Recommendation\nPapers:\nVrijenhoek et al.
