Negation and Natural Language Inference

This repository contains code of the EMNLP2020 paper "An Analysis of Natural Language Inference Benchmarks through the Lens of Negation". Paper link: https://www.aclweb.org/anthology/2020.emnlp-main.732.pdf
Authors: Md Mosharaf Hossain, Venelin Kovatchev, Pranoy Dutta, Tiffany Kao, Elizabeth Wei and Eduardo Blanco

Data Requirements

Download RTE, SNLI, and MNLI using "download_glue_data.py" script of https://github.com/nyu-mll/GLUE-baselines.

python ./data/download_glue_data.py --data_dir ./data/GLUE --tasks RTE,SNLI,MNLI

Python Requirements

Python 3.6+ (Recommended: Python 3.7)
Python packages: list of packages are provided in ./env-setup/requirements.txt file.
(We used an older version of the huggingface transformers (version 2.1.1) package).

# Create virtual env (Assuming you have Python 3.7 installed in your machine) -> optional step
python3 -m venv your_location/negation-and-nli
source your_location/negation-and-nli/bin/activate

# Install required packages -> required step
pip install -r ./env-setup/requirements.txt

Fine-tune Transformer systams and evaluate on the original dev splits

At the very begining, below directories need to be created. The predicted labels are saved in "outputs/predictions" directory and the fine-tuned models are saved in the "outputs/models" directory.

mkdir outputs
mkdir outputs/predictions
mkdir outputs/models

Fine-tune the transformers using RTE training split and evaluate on the RTE dev split:

sh rte-train.sh

Fine-tune the transformers using SNLI training split and evaluate on the SNLI dev split:

sh snli-train.sh

Fine-tune the transformers using MNLI training split and evaluate on the MNLI dev split:

sh mnli-train.sh

Evaluate the fine-tuned systems on new benchmarks containing negations

Evaluate on new RTE benchmark

sh rte-evaluate.sh

Evaluate on new SNLI benchmark

sh snli-evaluate.sh

Evaluate on new MNLI benchmark

sh mnli-evaluate.sh

Results

Results (Table 7 of our paper) can be achieved by the below script.

  python evaluate.py --corpus corpus_name

• Arguments: --corpus: Name of the corpus (e.g., rte or snli or mnli)

New NLI benchmarks containing negation

The annotation files of the new NLI benchmarks containing negation are given below.
RTE: ./data/new_benchmarks/clean_data/RTE.txt
SNLI: ./data/new_benchmarks/clean_data/SNLI.txt
MNLI: ./data/new_benchmarks/clean_data/MNLI.txt
