This program provides the implementation of the capsule network-based model CapsE as described in the paper:

      }

• Python 3
• Tensorflow >= 1.6

    $ python CapsE.py --embedding_dim 100 --num_epochs 31 --num_filters 50 --learning_rate 0.0001 --name FB15k-237 --useConstantInit --savedEpochs 30 --model_name fb15k237
    
    $ python CapsE.py --embedding_dim 100 --num_epochs 31 --num_filters 400 --learning_rate 0.00001 --name WN18RR --savedEpochs 30 --model_name wn18rr

Depending on the memory resources, you should change the values of --num_splits to a suitable value to get a faster process. To get the results (supposing num_splits = 8):

    $ python evalCapsE.py --embedding_dim 100 --num_filters 50 --name FB15k-237 --useConstantInit --model_index 30 --model_name fb15k237 --num_splits 8 --decode
    
    $ python evalCapsE.py --embedding_dim 100 --num_filters 400 --name WN18RR --model_index 30 --model_name wn18rr --num_splits 8 --decode

As in an agreement, you have to cite the paper Search Personalization with Embeddings whenever SEARCH17 is used to produce your published results. Unzip doc2vec.200.zip in the data/SEARCH17 folder.

At the moment, I cannot release the text because of the privacy issues.
