SME

The architecture of this package has been designed by Xavier Glorot (https://github.com/glorotxa), with some contributions from Antoine Bordes (https://www.hds.utc.fr/~bordesan).

Update (Nov 13): the code for Translating Embeddings (see https://everest.hds.utc.fr/doku.php?id=en:transe) has been included along with a new version for Freebase (FB15k).

1. Overview

This package proposes scripts using Theano to perform training and evaluation on several datasets of the models:

• Structured Embeddings (SE) defined in (Bordes et al., AAAI 2011);
• Semantic Matching Energy (SME_lin & SME_bil) defined in (Bordes et al., MLJ 2013);
• Translating Embeddings (TransE) defined in (Bordes et al., NIPS 2013).
• TATEC defined in (Garcia-Duran et al., ECML14, arxiv15).

Please refer to the following pages for more details and references:

• https://everest.hds.utc.fr/doku.php?id=en:smemlj12
• https://everest.hds.utc.fr/doku.php?id=en:transe
• https://everest.hds.utc.fr/doku.php?id=en:2and3ways

Content of the package:

• model.py : contains the classes and functions to create the different models and Theano functions (training, evaluation...).
• {dataset}_exp.py : contains an experiment function to train all the different models on a given dataset.
• The data/ folder contains the data files for the learning scripts.
• in the {dataset}/ folders:
  • {dataset}_parse.py : parses and creates data files for the training script of a given dataset.
  • {dataset}_evaluation.py : contains evaluation functions for a given dataset.
  • {dataset}_{model_name}.py : runs the best hyperparameters experiment for a given dataset and a given model.
  • {dataset}_{model_name}.out : output we obtained on our machines for a given dataset and a given model using the script above.
  • {dataset}_test.py : perform quick runs for small models of all types to test the scripts.

The datasets currently available are:

• Multi-relational benchmarks (Kinhsips, UMLS & Nations -- Tensor folder) to be downloaded from https://everest.hds.utc.fr/doku.php?id=en:smemlj12
• WordNet (WN folder) to be downloaded from https://everest.hds.utc.fr/doku.php?id=en:smemlj12
• Freebase (FB folder) used in (Bordes et al., AAAI 2011) to be downloaded from https://everest.hds.utc.fr/doku.php?id=en:smemlj12
• Freebase15k (FB15k folder) used in (Bordes et al., NIPS 2013) to be downloaded from https://everest.hds.utc.fr/doku.php?id=en:transe
• Synthethic family database (Family folder) user is (Garcia-Duran et al. arxiv15a) to be downloaded from https://everest.hds.utc.fr/doku.php?id=en:2and3ways

2. 3rd Party Libraries

You need to install Theano to use those scripts. It also requires: Python >= 2.4, Numpy >=1.5.0, Scipy>=0.8. The experiment scripts are compatible with Jobman but this library is not mandatory.

3. Installation

Put the script folder in your PYTHONPATH.

4. Data Files Creation

Put the absolute path of the downloaded dataset (from: https://everest.hds.utc.fr/doku.php?id=en:smemlj12 or https://everest.hds.utc.fr/doku.php?id=en:transe) at the beginning of the {dataset}_parse.py script and run it (the SME folder has to be your current directory). Note: Running Tensor_parse.py generates data for both Kinhsips, UMLS & Nations.

5. Training and Evaluating a Model

Simply run the corresponding {dataset}_{model_name}.py file (the SME/{dataset}/ folder has to be your current directory) to launch a training. When it's over, running {dataset}_evaluation.py with the path to the best_valid_model.pkl of the learned model runs the evaluation on the test set

6. Citing

If you use this code, you could provide the link to the github page: https://github.com/glorotxa/SME . Also, depending on the model used, you should cite either the paper on Structured Embeddings (Bordes et al., AAAI 2011), on Semantic Matching Energy (Bordes et al., MLJ 2013) or on Translating Embeddings (Bordes et al., NIPS 2013).
