Workshop on LLM & Agents for Recommendation Systems

The Web Conference 2026 (WWW'26) • April 13–17, 2026 • Dubai, UAE

Abstract

Recommendation systems power much of the web economy, influencing how people discover products, content, and services. With the emergence of Large Language Models and autonomous agents, these systems are undergoing a major shift from traditional centralized pipelines to agentic ecosystems that can plan, reason, negotiate, and interact across the entire journey of discovery, personalization, and fulfillment. Large Language Models introduce new capabilities for multimodal reasoning, natural language grounding, and conversational personalization, enabling systems that adapt and respond with greater context and coherence. At the same time, multi agent systems create opportunities for richer collaboration among buyers, sellers, and platforms, while also raising important challenges in interpretability, robustness, governance, and evaluation. Conventional short term metrics such as clicks and conversions are no longer sufficient to measure coordination quality, long horizon impact, trust, or fairness across stakeholders. This workshop brings together researchers and practitioners in recommendation systems, multi agent learning, information retrieval, and mechanism design to explore principles for transparent, scalable, and responsible agent driven personalization. Through contributions on architectures, evaluation, trust, fairness, and real world deployments, the workshop aims to shape the next generation of adaptive, explainable, and societally aligned recommendation ecosystems.

Invited Speakers

Call for Papers

We invite submissions exploring the intersection of Large Language Models (LLMs), intelligent agents, and recommendation systems. This workshop aims to advance the understanding of how LLM-based agents can enhance personalization, user interaction, and decision-making in recommendation systems.
