Relation-aware Heterogeneous Graph for User Profiling [article]

Qilong Yan, Yufeng Zhang, Qiang Liu, Shu Wu, Liang Wang
2021 pre-print
To solve these issues, we propose to leverage the relation-aware heterogeneous graph method for user profiling, which also allows capturing significant meta relations.  ...  Via such interactions on different relation types, our model can generate representations with rich information for the user profile prediction.  ...  To that end, we propose Relationaware Heterogeneous Graph Network for user profiling (RHGN) that can model multiple relations on the heterogeneous graph.  ...

ATBRG: Adaptive Target-Behavior Relational Graph Network for Effective Recommendation [article]

Yufei Feng, Binbin Hu, Fuyu Lv, Qingwen Liu, Zhiqiang Zhang, Wenwu Ou
2020 arXiv   pre-print
In this work, we propose a new framework named Adaptive Target-Behavior Relational Graph network (ATBRG for short) to effectively capture structural relations of target user-item pairs over KG.  ...  Existing methods either explore independent meta-paths for user-item pairs over KG, or employ graph neural network (GNN) on whole KG to produce representations for users and items separately.  ...  Until now, given a target user-item pair ⟨u, i⟩, we have the profile embeddings for user u and item i, and knowledge aware embedding from adaptive target-behavior relational graph for user behaviors and  ...
