Centrum Wiskunde & Informatica (CWI) has a vacancy in the Human-Centered Data Analytics research group for a talented Postdoc position on normative diversity in news recommendations.
Job description
Do you want to work on news recommendation technology that focuses on informing readers, rather than merely optimizing for clicks? We are looking for a talented postdoctoral researcher (m/f/x) to work with us on developing recommender systems that prioritize normative diversity.
Incorporating normative diversity into the design of news recommender systems has gained increasing attention in recent years, but as of yet production-ready solutions remain lacking. Over the course of this project, we will work on one of multiple lines of research necessary to take the field from theoretical notions towards solutions with societal impact. Example research lines include, but are not limited to:
- Efficient reranking of a recommendation towards multiple normative goals
- Conducting experiments with readers to test whether information needs are satisfied
- Building a dashboard the newsroom can use to control the recommender system
- Building NLP pipelines to automatically extract relevant information from text
Potential candidates can pick one of the suggested topics, but are also welcome to propose their own ideas within the broad subject of normative news recommender system design. The project is positioned within both CWI’s Human-Centered Data Analytics group, and the interdisciplinary AI, Media and Democracy Lab, which investigates how AI-driven applications in the media change the public sphere, civic engagement and economic competition.
Requirements
Candidates are required to have a PhD degree in Artificial Intelligence or related fields, such as Computer Science, Data Science, Information Science or Computational Social Science. Desired qualifications for candidates include:
- Theoretical knowledge of and practical experience with recommender systems;
- Knowledge of and experience with conceptualizing diversity, or alternatively fairness/bias/inclusivity in data and systems;
- Experience in working together with a team of people from different disciplines and/or between academia and industry;
- Excellent verbal and written communication skills in English.
Candidates who possess most but not all of these qualifications are welcome to apply. Candidates who will soon finalize their PhD are also eligible.
