O->ConBART 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 a modification to the BART architecture and operates on individual sentences. It is intended to be guided by a document-level simplification 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 use this model in PyTorch:

python

from plan_simp.models.bart import load_simplifier

simplifier, tokenizer, hparams = load_simplifier("liamcripwell/o-conbart")

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

Generation and evaluation can also be run from the terminal.

bash

python plan_simp/scripts/generate.py dynamic
  --clf_model_ckpt=liamcripwell/pgdyn-plan
  --model_ckpt=liamcripwell/o-conbart
  --test_file=<test_data>
  --doc_id_col=pair_id
  --context_dir=<context_dir>
  --reading_lvl=s_level
  --context_doc_id=c_id
  --out_file=<output_csv>


python plan_simp/scripts/eval_simp.py
