INTRODUCTION

Recent years have witnessed the fast development of the emerg- ing topic of Graph Machine Learning for Recommender Systems (GML4Rec). GML4Rec employs advanced graph machine learning approaches to model users’ preferences and intentions on items as well as items’ characteristics for improving the recommenda- tion performance. Different from other RS approaches, including content-based filtering and collaborative filtering, GML4Rec ap- proaches are built on graphs where the important objects, e.g., users, items and attributes, are either explicitly or implicitly con- nected. With the rapid development of graph learning techniques such as GNNs, exploring and exploiting the homogeneous or het- erogeneous relations in graphs is becoming a promising direction for building more effective RS. Meanwhile, by matching the demon- strated challenges to the research progress already achieved, we have some open research directions need to be further explored, e.g., interpretability, fairness, and large-scale adaptability for GML4Rec. Therefore, we propose the GML4Rec workshop at ICDM’23, which provides a venue to gather both the academia and industry re- searchers/practitioners to present the recent progress of GML4Rec

TOPICS OF INTEREST

In this workshop, we aim to discuss the latest research advances in the the- oretical foundations and practical application methods of GML4Rec. We invite submissions that focus on recent advances in the re search/development of GML4Rec along with their applications. Theory and methodology papers are welcome from any of the following areas, including but not limited to:
• Graph machine learning enhanced collaborative filtering
• Graph machine learning for sequential recommendation
• Graph machine learning for Recommender Systems by incor porating side information
• Graph machine learning strategies/algorithms for Recommender Systems
• Graph machine learning architectures for Recommender Sys tems
• Graph machine learning for self-evolutionary Recommender Systems
• Graph machine learning for explainable/interpretable Recom mender Systems
• Graph machine learning for robust/fair Recommender Systems
• Online graph machine learning based Recommender Systems

and applications papers focused on but not limited to:
• E-commerce platforms
• Streaming platforms
• Social networks
• Food and beverage

CALL FOR PAPER

We invite the submission of regular research papers (max 8 pages plus 2 extra pages), including all content and references. Submissions must be in PDF format, and formatted according to the new Standard IEEE Conference Proceedings Template. We especially invite submissions for dedicated efforts for developing more advanced techniques that are able to advance the technologies of graph construction, information propagation, and side attributes aggregation in GML4Rec, and further promote the research activities in interpretability, robustness, fairness, self-evolution, and large-scale adaptability for realizing desired GML4Rec. For more questions about the workshop and submissions, please send email to ruochen1003@foxmail.com . The submission link is GML4Rec2023
