A Survey on Data-Centric Recommender Systems
CoRR(2024)
摘要
Recommender systems (RS) have become essential tools for mitigating
information overload in a range of real-world scenarios. Recent trends in RS
have seen a paradigm shift, moving the spotlight from model-centric innovations
to the importance of data quality and quantity. This evolution has given rise
to the concept of data-centric recommender systems (Data-Centric RS), marking a
significant development in the field. This survey provides the first systematic
overview of Data-Centric RS, covering 1) the foundational concepts of
recommendation data and Data-Centric RS; 2) three primary issues in
recommendation data; 3) recent research developed to address these issues; and
4) several potential future directions in Data-Centric RS.
