(Accepted by Expert Systems with Applications)

Installation

Create a conda environment with pytorch and scikit-learn :

conda create --name tkbc_env python=3.7
source activate tkbc_env
conda install --file requirements.txt -c pytorch

Then install the kbc package to this environment

python setup.py install

Datasets

To download the datasets, go to the ./tkbc/scripts folder and run:

chmod +x download_data.sh
./download_data.sh

GDELT dataset can be download here and rename the files without ".txt" suffix.

Once the datasets are downloaded, add them to the package data folder by running :

python tkbc/process_icews.py
python tkbc/process_yago.py
python tkbc/process_gdelt.py

This will create the files required to compute the filtered metrics.

Reproducing results

Run the following commands to reproduce the results

CUDA_VISIBLE_DEVICES=0 python tkbc/learner.py --dataset ICEWS14 --model TPComplEx --rank 1594 --emb_reg 1e-1 --time_reg 1e-4 

CUDA_VISIBLE_DEVICES=0 python tkbc/learner.py --dataset ICEWS05-15 --model TPComplEx --rank 886 --emb_reg 1e-2 --time_reg 1e-2  

CUDA_VISIBLE_DEVICES=0 python tkbc/learner.py --dataset yago15k --model TPComplEx --rank 1892 --no_time_emb --emb_reg 1e-1 --time_reg 1e-4
