Multi-view Prompting (MvP)

Quick Start • Trained Model • Paper • Citation

Repo for ACL 2023 paper MvP: Multi-view Prompting Improves Aspect Sentiment Tuple Prediction.

✨ Introduction

MvP is an element order-based prompt learning method:

• MvP unifies various tuple prediction tasks through the combination of elements:

• MvP aggregates multi-view results by considering permutations of elements:

🎯 Results

MvP achieves state-of-the-art performance across 10 datasets encompassing 4 ABSA tasks with a single model:

MvP with T5-base outperforms large language models ChatGPT (gpt-3.5-turbo) by a large margin, even in few-shot transfer settings:

🚀 Quick Start

⚙️ Setup

conda create -n mvp python=3.8
conda activate mvp
pip install torch==1.12.1+cu116 torchvision==0.13.1+cu116 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu116
pip install -r requirements.txt

🤖 Trained Model

We release the multi-task MvP model (one seed): mvp-unified-base [Google Drive]

You may download the model with gdown (pip install gdown):

pip install gdown
mkdir -p outputs && cd outputs
gdown 1FMTuS4DRquLjZ3xWHLDh25W31d4dgQph
tar -xvf unified_model.tar.gz
mv src/outputs/unified unified
cd ..

then run evaluation:

bash scripts/eval_unified.sh

then you will get following results in outputs/unified/top5_seed10/result.txt:

⚡️ Training

• Train unified models:

bash scripts/process_unify.sh  # process data
bash scripts/run_unified.sh

• Train separate models:

bash scripts/run_main.sh

• Train with low-resource or cross-task transfer settings:

bash scripts/run_low_resource.sh

• Evaluate ChatGPT (gpt-3.5-turbo) baselines:

bash scripts/run_llms.sh
python llms/eval.py
