Query: Balancing Multi-level Interactions for Session-based Recommendation   Predicting user actions based on anonymous sessions is a challenge to general
recommendation systems because the lack of user profiles heavily limits
data-driven models. Recently, session-based recommendation methods have
achieved remarkable results in dealing with this task. However, the upper bound
of performance can still be boosted through the innovative exploration of
limited data. In this paper, we propose a novel method, namely Intra-and
Inter-session Interaction-aware Graph-enhanced Network, to take inter-session
item-level interactions into account. Different from existing intra-session
item-level interactions and session-level collaborative information, our
introduced data represents complex item-level interactions between different
sessions. For mining the new data without breaking the equilibrium of the model
between different interactions, we construct an intra-session graph and an
inter-session graph for the current session. The former focuses on item-level
interactions within a single session and the latter models those between items
among neighborhood sessions. Then different approaches are employed to encode
the information of two graphs according to different structures, and the
generated latent vectors are combined to balance the model across different
scopes. Experiments on real-world datasets verify that our method outperforms
other state-of-the-art methods.
