RECON

This is the code for the paper 'RECON: Relation Extraction using Knowledge Graph Context in a Graph Neural Network'.

Please note, we recieved multiple queries regarding why we have not used BERT as context aggregator instead of GNN. We tried it and performance was quite low (in the range of 0.76 F1Score on Wikidata dataset). Hence we decided to ignore BERT.

Dataset

The datasets can be downloaded from the below link

Wikidata

NYT

Glove embedding can be obtained from below link:

glove.6B.zip

Setup

Requires python3, torch>=1.4.0

Running

Train

The parameters are in the config file. Download the datasets, embeddings etc. and place in the expected locations.

mkdir data
cd data
unzip WikipediaWikidataDistantSupervisionAnnotations.v1.0.zip unzip glove.6B.zip
cp glove.6B/glove.6B.50d.txt WikipediaWikidataDistantSupervisionAnnotations.v1.0/enwiki-20160501/

In case nltk modules are not downloaded please run the below commands in a python interpreter:

import nltk
nltk.download('punkt')

If there are any relations to not be trained place them in ../resources/property_blacklist.txt else ignore the error of this file not being present.

Please ensure all the file paths are appropriate and run below commands for training the desired configurations of RECON

RECON_EAC set the python train.py

Test

Ensure the right model is being loaded(model/file name needs to be edited in code) and run

python test.py -sf=<path to the model folder>
