CENET: Contrastive Event Network

This is the official code base of the paper

Temporal Knowledge Graph Reasoning with Historical Contrastive Learning

Statistics of Datasets

Preprocessing

cd data/YAGO
python get_history_graph.py

Training and Testing

python main.py -d YAGO --description yago_hard --max-epochs 30 --oracle-epochs 20 --valid-epochs 5 --alpha 0.2 --lambdax 2 --batch-size 1024 --lr 0.001 --oracle_lr 0.001 --oracle_mode hard --save_dir SAVE --eva_dir SAVE

Note that we use hard mode for YAGO and WIKI, soft mode for event-based TKGs. The model performance fluctuates by less than 1% under different seed settings. For example, you will get better performance than the paper results under the setting of Seed 987.

You can use function load_all_answers_for_time_filter and split_by_time in script implemented by RE-GCN to get the time-aware filtered results.
