Speaker-Aware BERT for Multi-Turn Response Selection

This repository contains the source code and pre-trained models for the CIKM 2020 paper Speaker-Aware BERT for Multi-Turn Response Selection in Retrieval-Based Chatbots by Gu et al. <br>

Results

Dependencies

Python 3.6 <br> Tensorflow 1.13.1

Download

• Download the BERT released by the Google research, and move to path: ./uncased_L-12_H-768_A-12 <br>

• We also provide the BERT adapted on the Ubuntu V1 dataset, and move to path: ./uncased_L-12_H-768_A-12_adapted. You just need to fine tune it to reproduce our results. <br>

• Download the Ubuntu V1 dataset, and move to path: ./data/Ubuntu_V1_Xu/Ubuntu_Corpus_V1 <br>

Adaptation

Create the adaptation data.

cd data/Ubuntu_V1_Xu/
python create_adaptation_data.py 

Running the adaptation process.

cd scripts/
bash adaptation.sh

The adapted model will be saved to the path ./uncased_L-12_H-768_A-12_adapted. <br> Modify the filenames in this folder to make it the same as those in Google's BERT.

Training

Create the fine-tuning data.

cd data/Ubuntu_V1_Xu/
python create_finetuning_data.py 

Running the fine-tuning process.

cd scripts/
bash ubuntu_train.sh

Testing

Modify the variable restore_model_dir in ubuntu_test.sh

cd scripts/
bash ubuntu_v1_test.sh

A "output_test.txt" file which records scores for each context-response pair will be saved to the path of restore_model_dir. <br> Modify the variable test_out_filename in compute_metrics.py and then run the following command, various metrics will be shown.

python compute_metrics.py
