IMoJIE

Iterative Memory based Joint OpenIE

A BERT-based OpenIE system that generates extraction using an iterative Seq2Seq model, as described in the following publication, in ACL 2020, link

Installation Instructions

Use a python-3.6 environment and install the dependencies using,

pip install -r requirements.txt

This will install custom versions of allennlp and pytorch_transformers based on the code in the folder.

All reported results are based on pytorch-1.2 run on a TeslaV100 GPU (CUDA 10.0). Results may vary slightly with change in environment.

Execution Instructions

Data Download

bash download_data.sh

This downloads the (train, dev, test) data

Running the code

IMoJIE (on OpenIE-4, ClausIE, RnnOIE bootstrapping data with QPBO filtering)

python allennlp_script.py --param_path imojie/configs/imojie.json --s models/imojie --mode train_test 

Arguments:

• param_path: file containing all the parameters for the model
• s: path of the directory where the model will be saved
• mode: train, test, train_test

Important baselines:

IMoJIE (on OpenIE-4 bootstrapping)

python allennlp_script.py --param_path imojie/configs/ba.json --s models/ba --mode train_test 

CopyAttn+BERT (on OpenIE-4 bootstrapping)

python allennlp_script.py --param_path imojie/configs/be.json --s models/be --mode train_test --type single --beam_size 3

Generating aggregated data

Score using bert_encoder trained on oie4:

python imojie/aggregate/score.py --model_dir models/score/be --inp_fp data/train/4cr_comb_extractions.tsv --out_fp data/train/4cr_comb_extractions.tsv.be 

Score using bert_append trained on comb_4cr (random):

python imojie/aggregate/score.py --model_dir models/score/4cr_rand --inp_fp data/train/4cr_comb_extractions.tsv.be --out_fp data/train/4cr_comb_extractions.tsv.ba

Filter using QPBO:

python imojie/aggregate/filter.py --inp_fp data/train/4cr_comb_extractions.tsv.ba --out_fp data/train/4cr_qpbo_extractions.tsv

Note on the notation

We have been internally calling our model as "bert-append" (ba) until the day of submission of the paper and CopyAttention + BERT as "bert-encoder" (be). So you will find similar references throughout the code-base. In this context, IMoJIE is bert-append trained on qpbo filtered data.

Generating extractions

python standalone.py --inp input.txt --out output.txt

input.txt contains one sentence in each line output.txt contains the corresponding OpenIE extractions

This requires downloading the pre-trained models
