O->LED_para document simplification system

This is a pretrained version of the document simplification model presented in the Findings of ACL 2023 paper "Context-Aware Document Simplification".

It is a system based on the Longformer encoder-decoder that operates at the paragraph-level and is intended to be guided by a planner.

Target reading levels (1-4) should be indicated via a control token prepended to each input sequence ("<RL_1>", "<RL_2>", "<RL_3>", "<RL_4>"). If using the terminal interface, this will be handled automatically.

How to use

It is recommended to use the plan_simp library to interface with the model.

Here is how to load this model in PyTorch:

python

# loading
from plan_simp.models.bart import load_simplifier
simplifier, tokenizer, hparams = load_simplifier("liamcripwell/o-ledpara")

# generation
from plan_simp.scripts.generate import Launcher
launcher = Launcher()
launcher.dynamic(model_ckpt="liamcripwell/o-ledpara", clf_model_ckpt="liamcripwell/pgdyn-plan", **params)

Plan-guided generation and evaluation can be run from the terminal (see the repo for more details).

bash

python doc_simp/scripts/generate.py dynamic
