NeuralKG is a python-based library for diverse representation learning of knowledge graphs implementing Conventional KGEs, GNN-based KGEs, and Rule-based KGEs. We provide comprehensive documents for beginners and an online website to organize an open and shared KG representation learning community.

NeuralKG is built on PyTorch Lightning. It provides a general workflow of diverse representation learning on KGs and is highly modularized, supporting three series of KGEs. It has the following features:

• Support diverse types of methods. NeuralKG, as a library for diverse representation learning of KGs, provides implementations of three series of KGE methods, including Conventional KGEs, GNN-based KGEs, and Rule-based KGEs.

• Support easy customization. NeuralKG contains fine-grained decoupled modules that are commonly used in different KGEs, including KG Data Preprocessing, Sampler for negative sampling, Monitor for hyperparameter tuning, Trainer covering the training, and model validation.

• long-term technical maintenance. The core team of NeuralKG will offer long-term technical maintenance. Other developers are welcome to pull requests.

There is a demonstration of NeuralKG.

Step1 Create a virtual environment using Anaconda and enter it

conda create -n neuralkg python=3.8
conda activate neuralkg

Step2 Install the appropriate PyTorch and DGL according to your cuda version

Here we give a sample installation based on cuda == 11.1

• Install PyTorch

pip install torch==1.9.1+cu111 -f https://download.pytorch.org/whl/torch_stable.html

• Install DGL

pip install dgl-cu111 dglgo -f https://data.dgl.ai/wheels/repo.html

Step3 Install package

• From Pypi

pip install neuralkg

• From Source

git clone https://github.com/zjukg/NeuralKG.git
cd NeuralKG
python setup.py install

# Use bash script
sh ./scripts/your-sh

# Use config
python main.py --load_config --config_path <your-config>

python main.py --test_only --checkpoint_dir <your-model-path>

NeuralKG utilizes Weights&Biases supporting various forms of hyperparameter optimization such as grid search, Random search, and Bayesian optimization. The search type and search space are specified in the configuration file in the format "*.yaml" to perform hyperparameter optimization.

The following config file displays hyperparameter optimization of the TransE on the FB15K-237 dataset using bayes search:

command:
  - ${env}
  - ${interpreter}
  - ${program}
  - ${args}
program: main.py
method: bayes
metric:
  goal: maximize
  name: Eval|hits@10
parameters:
  dataset_name:
    value: FB15K237
  model_name:
    value: TransE
  loss_name:
    values: [Adv_Loss, Margin_Loss]
  train_sampler_class:
    values: [UniSampler, BernSampler]
  emb_dim:
    values: [400, 600]
  lr:
    values: [1e-4, 5e-5, 1e-6]
  train_bs:
    values: [1024, 512]
  num_neg:
    values: [128, 256]

There are some reproduced model results on FB15K-237 dataset using NeuralKG as below. See more results in here

*:There is a label leakage error in KBAT, so the corrected result is poor compared with the paper result. Details in deepakn97/relationPrediction#28

😃We use colab to provide some notebooks to help users use our library.
