Hearst Patterns Revisited: Automatic Hypernym Detection from Large Text Corpora

Project README

Hypernymy Suite

HypernymySuite is a tool for evaluating some hypernymy detection modules. Its predominant focus is reproducing the results for the following paper.

Stephen Roller, Douwe Kiela, and Maximilian Nickel. 2018. Hearst Patterns Revisited: Automatic Hypernym Detection from Large Text Corpora. ACL. (arXiv)

We hope that open sourcing our evaluation will help facilitate future research.


You can produce results in a JSON format by calling main.py:

python main.py cnt --dset hearst_counts.txt.gz

These results can be made machine readable by piping them into compile_table:

python main.py cnt --dset hearst_counts.txt.gz | python compile_table.py

To generate the full table from the report, you may simply use generate_table.sh:

bash generate_table.sh results.json

Please note that due to licensing concerns, we were not able to release our train/validation/test folds from the paper, so results may differ slightly than those reported.


The module was developed with python3 in mind, and is not tested for python2. Nonetheless, cross-platform compatibility may be possible.

The suite requires several packages you probably already have installed: numpy, scipy, pandas, scikit-learn and nltk. These can be installed using pip:

pip install -r requirements.txt

If you've never used nltk before, you'll need to install the wordnet module.

python -c "import nltk; nltk.download('wordnet')"

On OS X, you may need to install coreutils and gnu-sed for the script download_data.sh to run correctly. These can be installed using brew:

brew install coreutils gnu-sed

After installation, you will either need to modify download_data.sh to run gsort and gsed instead of sort and sed, or alternatively add a "gnubin" directory to your PATH from your bashrc:


For more information, see brew info coreutils or brew info gnu-sed.

Evaluating your own model

You can evaluate your own model in two separate ways. The simplest way is simply to create a copy of example.tsv, and fill in your model's predictions in the sim column. You must include a prediction for every pair, but you may set the is_oov column to 1 to ensure it is correctly calculated.

You may then evaluate the model:

python main.py precomputed --dset example.tsv

You can also implement any model by extending the base.HypernymySuiteModel class and filling in your own implemenation for predict or predict_many.
