Most works in the field of recommender systems are focused on the matrix completion problem, where for each user-item-pair only one interaction (e.g., a rating) is considered. In many application domains, however, multiple user-item interactions of different types can be recorded over time, and this information can be used to build richer individual user models and to discover additional behavioral patterns that can be leveraged in the recommendation process.
In this tutorial, we review existing works that consider information from such sequentially-ordered user-item interaction logs in the recommendation process. Based on this review, we describe a categorization of the corresponding recommendation tasks and goals, present the algorithmic solutions in depth, discuss methodological approaches when benchmarking what we call sequence-aware recommender systems, and outline open challenges in the area.
