SciTLDR

This repository contains the dataset, model weights, and generation code for our paper "TLDR: Extreme Summarization of Scientific Documents".

Dataset

SciTLDR is split in to a 60/20/20 train/dev/test split. For each file, each line is a json, formatted as follows

{
   "source":[
      "sent0",
      "sent1",
      "sent2",
      ...
   ],
   "source_labels":[binary list in which 1 is the oracle sentence],
   "rouge_scores":[precomputed rouge-1 scores],
   "paper_id":"PAPER-ID",
   "target":[
     "author-tldr",
      "pr-tldr0", 
      "pr-tldr1",
      ... 
   ],
   "title":"TITLE"
}

The keys rouge_scores and source_labels are not necessary for any code to run, but we provide precomputed Rouge scores to encourage future research.

Requirements

We use Fairseq to train and evaluate our models. Install Fairseq as follows:

git clone fairseq repo #TODO figure out how to use specific version
cd fairseq
pip install --editable .

To install all other requirements, run pip install -r requirements.txt

For the evaluation, you will need files2rouge. Please follow the installation instructions here.

Data Preprocessing

In order to format the data to work for the Fairseq library, run:

cd SciTLDR-Data
export TASK=SciTLDR-A # Choose from {A, AIC, FullText}
chmod +x make_datafiles.sh
./make_datafiles.sh # BPE preprocess

$TASK/ctrl contains the dataset formatted with the control codes.

Generation

This code takes in a test.source file, in which each line is an input and outputs a test.hypo file with the predictions. See decoder_params for optimal decoder parameters for each version of the model.

python scripts/generate.py /path/to/modeldir/ SciTLDR-Data/SciTLDR-A/ctrl ./ --beam 2 --lenpen 0.4 --test_fname test.hypo

Evaluation

This script is a wrapper around ROUGE that takes in a test.hypo file and compares to a test.jsonl file.

python scripts/cal-rouge.py /path/to/test.hypo SciTLDR-Data/SciTLDR-A/test.jsonl --workers 1
