Multi-Channel Graph Neural Network for Entity Alignment

The code of ACL2019 paper "Multi-Channel Graph Neural Network for Entity Alignment". The paper could be found at here.

Dependencies

Note: tensorboardX needs a TensorFlow installation to work correctly.

Code

Demo

To run a demo, simply execute the following script:

>> python example_train.py [GPU_id (if available)]
# example
>> python example_train.py 0

Customized running

To run the code on your own dataset:

  1. Format your data as described in Datasets;

  2. Execute rule mining with AMIE+;

    >> python format_data.py [PATH_TO_YOUR_DATASET]
    # example
    >> python format_data.py ./bin/DBP15k/fr_en

    Note: AMIE+ runs as an independent JAVA program. So you will need to wait until AMIE+ ended, and then input "amie ended" at the prompt to inform the python program to execute the next step.

  3. Customize your running

    • Customization with config.py

      from config import Config
      config = Config()
    • Set the hyper-parameters

      config.set_cuda(True) # set train on cpu or gpu
      config.set_dim(128) # set dimension number of embeddings and weight matrices
      config.set_align_gamma(1.0) # set gamma_1
      config.set_rel_align_gamma(1.0) # set gamma_2
      config.set_rule_gamma(0.12) # set gamma_r
      config.set_num_layer(2) # set layer number of MuGNN
      config.set_dropout(0.2) # set dropout rate
      config.set_learning_rate(0.001) # set learning rate
      config.set_l2_penalty(1e-2) # set L2 regularization coefficient
      config.set_update_cycle(5) # set negative sampling frequency
    • Set your dataset path

      config.init(YOUR_DATASET_PATH)
      # example
      config.init('./bin/DBP15k/fr_en')
    • Set log path

      config.init_log(LOG_FILE_PATH)
      # example
      config.init_log('./log/test')
    • Train

      config.train()

If you have any difficulties and questions regarding running the code, feel free to create an issue.

Datasets

Folder ./bin contains DBP15k and DWY100k datasets.

                  triples_kg2.txt

Data format

  • entity2id_kgx.txt: all entities from kgx with the corresponding ids. Format: entity_name + \t + id + \n;
  • relation2id_kgx.txt: all relations from kgx with the corresponding ids. Format: relation_name + \t + id + \n;
  • triples_kgx.txt: all triples from kgx. Format: entity1 + \t + entity2 + \t + relation + \n;
  • entity_seeds.txt: all entity seed alignments. Format: entity1 (from kg1) + \t + entity2 (from kg2) + \n;
  • train_entity_seeds.txt: entity seed alignments for training. Format: entity1 (from kg1) + \t + entity2 (from kg2) + \n;
  • test_entity_seeds.txt: entity seed alignments for test. Format: entity1 (from kg1) + \t + entity2 (from kg2) + \n;
  • relation_seeds.txt: all relation seed alignments. Format: relation1 (from kg1) + \t + relation2 (from kg2) + \n;
  • all2id_kgx.txt: all entities and relations from kgx with the corresponding ids. Format: entity/relation + \t + id + \n.

Note

  • The difference between arrangements of DBP15k and DWY100k is that DWY100k has split the train and test set of entity alignments but DBP15k has not;
  • Folder AMIE contains data arranged in the structure which is designed to be compatible with AMIE+;
  • triples_kgx.txt in folder AMIE is encoded with all2id_kgx.txt.
