Personalized knowledge-aware recommendation with collaborative and attentive graph convolutional networks

作者:

Highlights:

• A new framework (COAT) is proposed for personalized knowledge-aware recommendation.

• Collaborative and attentive GNNs are designed to jointly model the UI and KG graphs.

• Novel attention mechanisms are designed to achieve personalization.

• An efficient graph convolutional layer is employed to tackle the sparsity issue.

• COAT outperforms 10 state-of-the-art recommendation methods on benchmark datasets.
