To run the model the first thing to do is create a dataset. You need a file like data-sample.txt. The file must be tab-separated an with the following fields:

lexicalized dependency path between arguments (entities) of the relation, first entity second entity entity types of the first and second entity trigger word id of the sentence raw sentence pos tags of the entire sentence relation between the two entities if any (used only for evaluation)

In order to create the dataset you need the OiePreprocessor.py script once for each dataset partition: train, dev, and test.

python processing/OiePreprocessor.py --batch-name train data-sample.txt sample.pk 
python processing/OiePreprocessor.py --batch-name dev data-sample.txt sample.pk
python processing/OiePreprocessor.py --batch-name test data-sample.txt sample.pk

Now, your dataset with all the indexed features is in sample.pk

To train the model run the OieInduction.py file with all the required arguments:

python learning/OieInduction.py --pickled_dataset sample.pk --model_name discrete-autoencoder --model AC --optimization 1 --epochs 10 --batch_size 100 --relations_number 10 --negative_samples_number 5 --l2_regularization 0.1 --alpha 0.1 --seed 2 --embed_size 10 --learning_rate 0.1
