Overview

REval

Table of Contents

🎓   Introduction

REval is a simple framework for probing sentence-level representations of Relation Extraction models.

  Requirements

REval is tested with:

  • Python 3.7

🚀   Installation

With pip

<TBD>

From source

git clone https://github.com/DFKI-NLP/REval
cd REval
pip install -r requirements.txt

🔬   Probing

Supported Datasets

  • SemEval 2010 Task 8 (CoreNLP annotated version) [LINK]
  • TACRED (obtained via LDC) [LINK]

🔧   Usage

Step 1: create the probing task datasets from the original datasets.

SemEval 2010 Task 8

python reval.py generate-all-from-semeval \
    --train-file <SEMEVAL DIR>/train.json \
    --validation-file <SEMEVAL DIR>/dev.json \
    --test-file <SEMEVAL DIR>/test.json \
    --output-dir ./data/semeval/

TACRED

python reval.py generate-all-from-tacred \
    --train-file <TACRED DIR>/train.json \
    --validation-file <TACRED DIR>/dev.json \
    --test-file <TACRED DIR>/test.json \
    --output-dir ./data/tacred/

Step 2: Run the probing tasks on a model.

For example, download a Relation Extraction model trained with RelEx, e.g., the CNN trained on SemEval.

mkdir -p models/cnn_semeval
wget --content-disposition https://cloud.dfki.de/owncloud/index.php/s/F3gf9xkeb2foTFe/download -P models/cnn_semeval
python probing_task_evaluation.py \
    --model-dir ./models/cnn_semeval/ \
    --data-dir ./data/semeval/ \
    --dataset semeval2010 \
    --cuda-device 0 \
    --batch-size 64 \
    --cache-representations

After the run is completed, the results are stored to probing_task_results.json in the model-dir.
