Grid Tagging Scheme for Aspect-oriented Fine-grained Opinion Extraction. Zhen Wu, Chengcan Ying, Fei Zhao, Zhifang Fan, Xinyu Dai, Rui Xia. In Findings of EMNLP, 2020.
❗Note: Our opinion triplet datasets are completely from alignments of our previous work TOWE datasets and the original SemEval 2014, 2015, 2016 datasets. GTS datasets contain the cases of one aspect term corresponding to multiple opinion terms and one opinion term corresponding to multiple aspect terms.
[Data] [Pre-trained Model(from huggingface)]. Data format descriptions are here.
See requirement.txt or Pipfile for details
- pytorch==1.7.1
- transformers==3.4.0
- python=3.6
For example, you can use the folowing command to fine-tune Bert on the OPE task (the pre-trained Bert model is saved in the folder "pretrained/"):
python main.py --task pair --mode train --dataset res14
The best model will be saved in the folder "savemodel/".
For example, you can use the folowing command to test Bert on the OPE task:
python main.py --task pair --mode test --dataset res14
Note: In our pre-experiments, a smaller batch size and learning rate can achieve better performance on certain datasets, while we use a general setting in our paper to save time instead of adopting grid search.
