This software can be used to reproduce the results in our "SimplE Embedding for Link Prediction in Knowledge Graphs" paper. It can be also used to learn SimplE models for other datasets. The software can be also used as a framework to implement new tensor factorization models (implementations for TransE and ComplEx are included as two examples).

• Python version 2.7 or higher
• Numpy version 1.13.1 or higher
• Tensorflow version 1.1.0 or higher

To run a model M on a dataset D, do the following steps:

• cd to the directory where main.py is
• Run python main.py -m M -d D

Examples (commands start after $):

$ python main.py -m SimplE_ignr -d wn18
$ python main.py -m SimplE_avg -d fb15k
$ python main.py -m ComplEx -d wn18

Running a model M on a dataset D will save the embeddings in a folder with the following address:

$ <Current Directory>/M_weights/D/

As an example, running the SimplE_ignr model on wn18 will save the embeddings in the following folder:

$ <Current Directory>/SimplE_ignr_weights/wn18/

The best embeddings learned for SimplE_ignr and SimplE_avg on wn18 and fb15k can be downloaded from this link and this link respectively.

To use these embeddings, place them in the same folder as main.py, load the embeddings and use them.

Refer to the following publication for details of the models and experiments.
