    About

    The Context-Aware Recommender Systems (CARS) workshop explores the evolving role of contextual information in modern recommender systems. Recent advances highlight the importance of modeling dynamic, implicit, and complex contextual signals beyond traditional static factors. CARS 2026 aims to bring together researchers and practitioners to discuss novel approaches, including sequence-aware and latent context modeling, real-time context inference, and context representation learning. The workshop also emphasizes emerging application domains, such as education, financial, and health systems, where capturing rich contextual signals is essential for delivering relevant, personalized, and trustworthy recommendations.

  • Second International Workshop on Data Quality-Aware Multimodal Recommendation DaQuaMRec 26

    About

    The “Data Quality-Aware Multimodal Recommendation” (DaQuaMRec) workshop focuses on a fundamental challenge in modern recommender systems: the quality of the multimodal data they rely on. As recommendation models increasingly combine text, images, audio, and other signals, they enable richer personalization and more accurate suggestions across domains such as fashion, music, food, and digital media. Advances in deep learning and foundation models have accelerated progress in this space, but they have also made clear that model performance and fairness depend heavily on the reliability of the underlying data.

    DaQuaMRec provides a venue for researchers and practitioners to examine challenges such as noisy inputs, missing modalities, misaligned data, and embedded biases. These issues can undermine recommendation quality and lead to inaccurate or unfair outcomes. Through this workshop, we aim to encourage new research and practical solutions for understanding, evaluating, and improving data quality in multimodal recommendation.

  • Temporal Reasoning in Recommendation Systems RecTemp 26

    About

    RecTemp 2026 focuses on advancing temporal reasoning in recommender systems, addressing how evolving user preferences, sequential interactions, and contextual dynamics can be modeled over time. This year, the workshop highlights the growing role of large language models (LLMs) in time-aware recommendation, including their ability to reason over user behavior across sessions and longer horizons. We invite contributions on novel methods, empirical studies, and emerging ideas that integrate temporal dynamics into modern recommender systems.

  • Afternoon Workshops
  • Sixth Workshop on Recommender Systems for Human Resources RecSys in HR 26

    About

    The field of Human Resources (HR) is at the forefront of adopting AI technologies. According to PWC, over 40% of HR-functions of international companies use AI-applications. This so-called HR Technology (HR Tech) aims to replace or support Human Resource functions such as talent acquisition and management, employee compensation, workforce analytics, and performance management. Recommender Systems play an integral role in the rapid rise of HR Tech, ranging from assisting the talent acquisition process through matching and candidate screening, to broader tasks such as recommendations for upskilling. Alongside their growing use within the HR space, the European Commission has labeled such systems as “high-risk”, as automation here can directly impact the working lives of people.

  • Methodology First: Rethinking Research Assessment in RecSys FRAME 26

    About

    Recommender systems is a strongly empirical field, and existing literature has highlighted several methodological problems that make published findings harder to interpret, compare, and generalize, while contributing to a gap between academic evaluation and industry needs. FRAME aims to foster discussion and progress on stronger research assessment practices. The workshop features two tracks: a Research Papers track reviewed through a methodology-first, results-blind process, and an Experimental Methodologies track for full papers and position statements on best practices, protocol design, fair comparison, and missing resources for evaluation.

    Submissions due: July 20, 2026 — https://remaplab.github.io/frame2026/

  • The Fourth Music Recommender Systems Workshop MuRS 26

    About

  • The Third Workshop on Agentic and Generative AI for E-Commerce GenAI-eCom 26

    About

    The “Agentic and Generative AI for E-Commerce” workshop explores the rapidly evolving intersection of recommender systems, generative AI, and agentic AI in online retail. As AI systems evolve from passive generators to autonomous agents capable of planning, reasoning, and taking actions, e-commerce stands at the forefront of this transformation. The workshop fosters discussions on how agentic AI systems — autonomous agents that can browse, compare, negotiate, and purchase on behalf of users — alongside generative models, can transform personalization, product recommendations, content creation, and user engagement in e-commerce platforms.

    E-commerce companies face challenges such as lack of quality content, subpar user experience, and sparse datasets. Generative and agentic AI offer significant potential to address these, yet scaling these technologies presents challenges including hallucination, excessive costs, latency, and ensuring safe autonomous agent behavior.

  • Unified Search and Recommendation Workshop USRW 26

    About

    Search and recommendation have long been developed in parallel, despite serving the same discovery goal over shared item universes. The rise of Large Language Models and agentic systems is collapsing this divide, with unified architectures and generative retrieval increasingly powering both query-driven and feed-driven experiences. USRW brings together researchers and practitioners from the IR and RecSys communities to define shared tasks and datasets, compare unified architectures, align evaluation across paradigms, and foster cross-pollination between industry and academia. This is the inaugural edition of USRW, a full-day workshop designed to establish unified search-and-recommendation as a mainstream research and production reality.

  • The 5th Workshop on Causality, Counterfactuals and Sequential Decision-Making for Recommender Systems CONSEQUENCES 26

    About

    An increasing amount of research understands recommender systems as a decision-making problem, instead of a pure prediction problem. This view makes it clear that recommendation decisions on real-world platforms have consequences. Actions and decisions come in many forms, from selecting rankings to LLM tokens, and their consequences also vary: algorithms are often responsible for collecting training data for the next iteration, while algorithmic decisions also impact the utility that all stakeholders can get from participating on the platform.

    This is the fifth instalment of the CONSEQUENCES workshop series, which has seen significant interest from across academia and industry. Advances in the intersection of these fields foster progress in effective, efficient and fair use of logged data for both learning and evaluation, and can have a strong impact on practical systems.

  • Half-day: afternoon
  • The Second AltRecSys Workshop on Reimagining Recommender Systems Research & Practice AltRecSys 26

    About

    AltRecSys is back! As ACM RecSys turns 20, we take this milestone as an invitation to pause, take inventory, and reflect on what our rapidly expanding field may have overlooked. The workshop creates a space for alternative, provocative, and unconventional work that challenges dominant assumptions and familiar framings in recommender systems research and practice. This second edition emphasizes highly interactive discussions among researchers, practitioners, and other stakeholders, inviting reflection not only on how far the field has come, but also on where it might go if we allow ourselves to think differently.
