This repository holds the codes for [Dual Graph Attention Networks for Deep Latent Representation of Multifaceted Social Effects in Recommender Systems. (WWW 2019)](https://arxiv.org/abs/1903.10433). 
The requirements are Python 3.6 and Tensorflow 1.7.0.

We also release the public dataset Epinions used in our work and the trained model.

To reproduce the results in our paper, you can run

python test.py

To train the model, you can run

python train.py
    
and you will get similar results after about 20 epoches.

The build_dataset.py is to preprocess the dataset and outputs two .pkl files in /data. The input.py generates mini-batch samples.
The eval.py contains the calculation for evaluation metrics. The model.py implements the network model proposed in our paper.

If you use this code as part of any published research, please cite the following paper:
