This is the official code for the 2019 EMNLP paper, Do NLP Models Know Numbers? Probing Numeracy in Embeddings . This repository contains the code for the synthetic tasks described in Section 3 of the paper.
This code is written in python using PyTorch and AllenNLP.
An easy way to install the code is to create a fresh anaconda environment:
conda create -n numeracy python=3.6
source activate numeracy
pip install -r requirements.txt
Now you should be ready to go!
The three tasks in the paper (list maximum, number decoding, and addition) are separated into three different files. utils.py contains code for loading the embedding methods and creating the datasets.
See the scripts inside run_scripts/* to recreate the experiments in Table 4 of the paper.
Note: I have heavily refactored the paper's original code and simplified things. This, alongside updates to the libraries, means the results aren't exactly the same as those reported in the paper. However, although the exact numbers differ, the trends closely follow those in the paper. Also, note that there is relatively high variance in the individual runs. In future research papers, I recommend that you report the mean/median result over multiple runs. Moreover, to be fair to the different embedding methods, I recommend lightly tuning the hyperparameters of the probing classifier.
