This repository provides a reference implementation of the proposed model in the following paper:
Yongji Wu, Defu Lian, Shuowei Jin, Enhong Chen. Graph Convolutional Networks on User Mobility Heterogeneous Graphs for Social Relationship Inference. The 27th International Joint Conference on Artificial Intelligence (IJCAI 2019), Macao, China, August, 2019
Our implementation is based on: Thomas N. Kipf, Max Welling, Semi-Supervised Classification with Graph Convolutional Networks (ICLR 2017)
- TensorFlow >= 1.10
python setup.py install
python heter_gcn/unsupervised_train.py
python heter_gcn/semi_sup_train.py
where unsupervised_train.py is for unsupervised training, while semi_sup_train.py is for semi-supervised training when part of the ground truth social network is available.
The Austin dataset (Gowalla) is included in the dataset folder as an example. The provided partial social graph is a partial social network used for semi-supervised training which contains 30% of social pairs.
