Install

Make sure your local environment has the following installed:

python==3.6
pandas
tensorflow==1.10.0
numpy==1.16.2
pandas==1.0.3

Install the dependents using:

pip install -r requirements.txt

Run the experiments

To train the model, use:

python ./run.py --knowledge_model rotate --target_language ja --use_default

• You can use --knowledge_model transe to switch from KEnS(RotatE) to the KEnS(TransE).
• --target_language could be set as ja, es, el, en, fr.
• --use_default means to use the preset hyper-parameter combinations.
• By default, the trained models are saved in $PROJECT_DIR$/trained_model/kens-$KNOWLEDGE_MODEL$-$DIM$/$TARGET_LANGUAGE$.

To set your own hyper-parameters:

python ./run.py --knowledge_model rotate --target_language ja -d 400 -b 2048 -lr 1e-2 --rotate_gamma 24 --reg_scale 1e-4 --base_align_step 5 --knowledge_step_ratio 20 --align_lr 1e-3

Download the pre-trained KEnS(RotatE) model (dimension=400) for Japanese KG: https://drive.google.com/file/d/1GJJmkStYuRVfTYXi1OvtuCwVflkKaqD0/view?usp=sharing

To test the trained model with the ensemble techniques, use:

python ./test.py --knowledge_model rotate --target_language ja --model_dir $TRAINED_MODEL_DIR$  -d $YOUR_MODEL_DIM$
