PAED: Zero-Shot Persona Attribute Extraction in Dialogues

Python Versions PyTorch Versions

Overview

🔥 This is a repository for our paper (PAED: Zero-Shot Persona Attribute Extraction in Dialogues) accepted in ACL'23 (The 61st Annual Meeting of the Association for Computational Linguistics). (Author list: Luyao Zhu, Wei Li, Rui Mao, Vlad Pandelea and Erik Cambria.)

In this work, we develop a PAED dataset, PersonaExt, with 1,896 re-annotated triplets and 6,357 corrected utterance-triplet pairs. We present a generation-based framework for zero-shot PAED. A novel HNS strategy, Meta-VAE sampler with CSC, is presented to enhance the performance of our model. Our model achieves better results than strong baselines in zero-shot PAED and negative sampling.

Dataset

The dataset PersonaExt is publicly available, with 105 relation types.

Requirements and Installation

  • PyTorch >= 1.10.0
  • Python version >= 3.8
  • You may use the folowing instruction to intall the requirements.
pip install -r requirements.txt

Usage

To run this code, please use the following command (take split unseen_10_seed_0 as an example).

10 is the number of unseen labels; 0 is the random seed used for randomly selecting the 10 unseen labels.

python trainer_finetune.py

To change the number of test labels, you may find the variable num_test_labels in the 717th line in trainer_finetune.py and put any number from {5, 10, 15} into the list.

For example, to change the number of test labels into 5, you may set:

>>>num_test_labels=[5]

To change the random seeds for selecting the unseen labels, you may find the variable seeds in the 718th line in trainer_finetune.py and put any number from {0, 1, 2, 3, 4} into the list.

For example, to change the seed into 1, you may set:

>>>seeds=[1]

The default evaluation is tailored for the results of single triplet extraction. To get the evaluation for multiple triplet extraction for other dataset, e.g., fewrel, you may set the flag mode='multi' of the function run_eval. Additionally, you need to remember to place the target dataset under the directory of /outputs/data/splits/zero_rte/[YOURDATA]/unseen_[x]_seed_[x]/, which should conver train.json, dev.json and test.json.
