This repository contains the code for our COLING 2018 paper:

Dynamic Multi-Level Multi-Task Learning for Sentence Simplification.

Data Preprocessing

Please follow the instructions from Zhang et al. 2017 for downloading the pre-processed dataset. To build the .bin files please follow the instructions from See et al. 2017, or here.

Evaluation Set-Up

• Please follow the instructions from Zhang et al. 2017 for setting up the evaluation system.
• FKGL implementations can be found in this repo.
• Modify corresponding directories in evaluation_utils/sentence_simplification.py.
• Please note that evaluation metrics are calculated on corpus level.

Dependencies

python 2.7
