Installation

1. create a conda environment:

conda create -n tkg python=3.6 anaconda

2. run

source activate tkg
pip install -r requirements.txt

How to use?

1. To train the model run the following command.

source activate tkg
python main.py \
  --config_path "configs/dyrmlp.yml" \
  --data_dir "data/completion/" \
  --dataset "icews14" \
  --task "completion" \
  --max_time_range 3 \
  --do_test True \
  --batch_size 300 \
  --overwrite True \
  --resume_train False \
  --max_epochs 240 \
  --save_steps 30 \
  --eval_steps 60 \
  --neg_ratio 0 \
  --test_size 256 \
  --from_pretrained False \
  --fix_pretrained False \
  --verbose False \
  --save_eval True \
  --checkpoint "DyRMLP_2305-1921_240_icews14.pth"

important parameters:

• config_path: types and basic configurations of model, saved under the folder configs/. For DyRMLP model, use the value "configs/dyrmlp.yml"

• data_dir: the dataset folder for the experiment. Example: do the completion task, use "data/completion". Do the forecasting task, use "data/forecast"

• dataset: the name of the dataset for the experiment. Valid Values are the folders names under the 'data_dir' folder. For example, if want to do completion task on GDELT dataset, you can go to the "data/completion" and find a folder named "gdelt", then this value should be 'gdelt'.

• task: choose from "completion" or "forecasting"

• max_time_range. The default value is 3, corresponding to the Section 3.2.2 in the paper, the predefined time window size.

• do_test: True or False. Whether to do test on the testing dataset after training.

• batch_size: The default value is 16. Recommended value is 300

• overwrite: True or False. Whether to generate a new version of dataset object for the model. If you do some change on the dataset files under data/.../..., take the value as True. Otherwise, take it as False to save time.

• max_epochs: the default value is 30. How many epochs to train.

• neg_ratio: how many negative examples to generate for a positive example. Set it as 0 if you use dyrmlp model.\

• To do the ablation experiments, just change the certain parameter's value in the command line or in the config yaml file.

2. To directly evalute the model run the following command

source activate tkg
python main.py \
  --config_path "configs/dyrmlp.yml" \
  --data_dir "data/completion/" \
  --task "completion" \
  --dataset "gdelt" \
  --checkpoint "DyRMLP_0206-2144_14_gdelt.pth" \
  --do_train False \
  --do_test True \
  --max_time_range 3 \
  --overwrite False \
  --test_size 256 \
  --save_eval True

3. To reproduce the results for ICEWS14, ICEWS05-15, GDELT, run the following command:

source activate tkg
python main.py \
  --config_path "configs/dyrmlp.yml" \
  --data_dir "data/completion/" \
  --dataset "icews14" \
  --task "completion" \
  --max_time_range 3 \
  --do_test True \
  --batch_size 300 \
  --overwrite False \
  --resume_train False \
  --max_epochs 240 \
  --save_steps 240 \
  --eval_steps 240 \
  --neg_ratio 0 \
  --test_size 256

source activate tkg
python main.py \
  --config_path "configs/dyrmlp.yml" \
  --data_dir "data/completion/" \
  --dataset "icews05-15" \
  --task "completion" \
  --max_time_range 3 \
  --do_test True \
  --batch_size 300 \
  --overwrite False \
  --resume_train False \
  --max_epochs 200 \
  --save_steps 200 \
  --eval_steps 200 \
  --neg_ratio 0

source activate tkg
python main.py \
  --config_path "configs/dyrmlp.yml" \
  --data_dir "data/completion/" \
  --dataset "gdelt" \
  --task "completion" \
  --max_time_range 3 \
  --do_test True \
  --batch_size 300 \
  --overwrite False \
  --resume_train False \
  --max_epochs 5 \
  --save_steps 5 \
  --eval_steps 5 \
  --neg_ratio 0

4. if you want to do experiment using other datasets, save the corresponding dataset files under specific data_dir and change the parameter dataset to the folder name you have saved. Format requirments of dataset files are in the Section Structures.

Structures

• cache/ (optional): save the trained models, etc caches
• configs/ (important): save the configurations of models. Each model to run must have a yaml file saved under this folder
• data/ (important): dataset to experiments. Dataset saved as a folder under specific tasks folder. In each dataset folder, there must be three files: stat.txt, test.txt and train.txt. valid.txt is optional.
  • stat.txt has three elements: the number of enitites, the number of relations and the number of timepoints. Split by tab.
  • train/test/valid.txt follows the format: each line has four elements: subject entity id, relation id, object entity id and timepoint. They are split by tab.
