  • Privacy-Preserving and Responsible Personalization: On-device and federated learning, differential privacy, and lightweight or distilled LLMs for sensitive wellbeing data.
  • Human-Centered and Human-in-the-Loop Evaluation: Evaluation methodologies that capture individual outcomes, long-term effects, and user trust, including interactive and participatory evaluation.
  • LLM-based User Simulation and Benchmarking: Simulation of user behavior and feedback for scalable evaluation, benchmarking, and stress-testing of wellbeing RSs.
  • Deployment and Real-World Challenges: System design, safety boundaries, and deployment of LLM-based recommenders in real-world, resource-constrained, or web-scale wellbeing applications.

Submission Guidelines

All papers must use the CEUR-WS template in one-column format.

Paper Types:

  • Regular papers: 10 or more standard pages, including references.

  • The Libertinus font family is mandatory; installation instructions are included in the template.

Papers that do not comply with these requirements will not be suitable for publication in CEUR-WS.

At least one author of each accepted paper must attend the workshop in-person or online and present the paper. All submitted papers will be evaluated by at least two members of the program committee, based on originality, significance, relevance, and technical quality. Submissions should be single-blinded, i.e. authors’ names should be included in the submissions.
