This is the data and coded for our EMNLP 2021 paper TimeTraveler: Reinforcement Learning for Temporal Knowledge Graph Forecasting

Qucik Start

Data preprocessing

This is not necessary, but can greatly shorten the experiment time.

python3 preprocess_data.py --data_dir data/ICEWS14

Dirichlet parameter estimation

If you use the reward shaping module, you need to do this step.

python3 mle_dirichlet.py --data_dir data/ICEWS14 --time_span 24

Train

you can run as following:

python3 main.py --data_path data/ICEWS14 --cuda --do_train --reward_shaping --time_span 24

Test

you can run as following:

python3 main.py --data_path data/ICEWS14 --cuda --do_test --IM --load_model_path xxxxx
