Recommender systems now shape what people know, choose, and experience. In the generative AI era, recommendation is becoming an ongoing relationship among people, agents, and platforms. User-facing agents can interpret goals, maintain memory, use tools, and act across multiple steps, while agentic workflows can revise, evaluate, and deploy recommendation models. These capabilities promise more adaptive support, but they may also shift control over how preferences are represented, decisions are executed, and systems evolve. Human-centered recommendation must therefore ask whose goals agents serve, how people can inspect and correct their behavior, and whether their effects remain beneficial over time. Organized around agency, alignment, and long-term value, the 3rd Workshop on Human-Centered Recommender Systems (HCRS@WWW 2027) brings together recommender systems, information retrieval, human-computer interaction, responsible AI, and social computing to develop methods, evaluations, and safeguards that keep agent-mediated recommendation accountable to people.

Workshop Objectives

This workshop encourages new theoretical frameworks, interdisciplinary approaches, and perspectives for human-centered recommender systems in the generative AI era. We advocate rigorous evaluation through user studies, simulation-based protocols, and off-policy metrics that move beyond engagement to capture satisfaction, trust, and long-term welfare. Participants will explore how large language models and autonomous agents can strengthen, rather than undermine, meaningful human control over recommendation. Rather than centering on agent architectures and system capabilities, the workshop foregrounds the human stakes of this transition: whose goals are served, who retains oversight, and who bears the consequences.

Call for Papers

The workshop is organized around three thematic pillars that address the human stakes of agent-mediated recommendation:

  • Agency: Human control over goals and delegation. Extending human capabilities while preserving meaningful control over preference representation, memory, tools, permissions, and consequential actions. Topics include:
    • Personal agents for discovery and decision support.
    • Goal expression, revision, and mixed-initiative interaction.
    • User control of memory, tools, data, and permissions.
    • Consent, contestability, correction, and human override.
    • Recommendations interpreted jointly by people and agents.
    • Platform access, competition, and user choice.
  • Alignment: Systems aligned with human intentions and values. Keeping user-facing agents and self-evolving recommendation systems responsive to human intentions through feedback, verification, and accountable oversight. Topics include:
    • Preference elicitation under ambiguity, conflict, and drift.
    • Human and agent feedback, rubrics, and reward models.
    • Verified agent harnesses for recommender-system development and deployment.
    • Provenance, revision, deletion, and contamination of user and agent memory.
    • Safe tool use, reflection, coordination, and self-improvement in recommendation pipelines.
    • Reward hacking, capability drift, and failed exploration in adaptive recommender systems.
    • Reproducibility, privacy, fairness, and accountable audits of recommender systems.
  • Long-term Value: Benefits for people and ecosystems over time. Moving beyond one-step relevance and short-term engagement to assess cumulative effects on users, creators, communities, and platforms. Topics include:
    • Long-horizon user modeling and preference formation.
    • Satisfaction, learning, well-being, and autonomy.
    • Continual adaptation and delayed feedback.
    • Value for users, creators, and communities.
    • Simulation-based and longitudinal evaluation.
    • Process evaluation, attribution, and red teaming.
    • Manipulation, dependency, filter bubbles, and harm.
