Datasets

The training data comes from four domains: Restaurant(R) 、 Laptop(L) 、 Service(S) 、 Devices(D).

The in-domain corpus(used for training BERT-E) come from yelp and amazon reviews.

Click here to get BERT-E (BERT-Extented) , and the extraction code is by0i. (Please specify the directory where BERT is stored in modelconfig.py.)

Usage

1. Domain-Adaptive Pseudo Labeling

To assign pseudo labels to unlabeled data in the target domain, run below code:

bash pseudo_label.sh

2. Domain-Adaptive Language Modeling

Train a domain-adaptive language model, generate target-domain labeled data, and finally use the generated data for the main tasks. We use LSTM and GPT2 as decoder in language modeling respectively.

2.1 To train the GPT2-based DALM for data generation and evaluation, run below code:

bash GPT2.sh

2.2 To train the LSTM-based DALM for data generation and evaluation, run below code:

bash LSTM.sh
