This repository contains the source code and datasets for the IEEE/ACM Transactions on Audio, Speech and Language Processing paper Utterance-to-Utterance Interactive Matching Network for Multi-Turn Response Selection in Retrieval-Based Chatbots by Gu et al.

Python 2.7
Tensorflow 1.4.0

Your can download the processed datasets used in our paper here and unzip it to the folder of data.
Ubuntu_V2

cd scripts
bash ubuntu_train.sh

The training process is recorded in log_train_UbuntuV2.txt file.

bash ubuntu_test.sh

The testing process is recorded in log_test_UbuntuV2.txt file. And your can get a ubuntu_test_out.txt file which records scores for each context-response pair. Run the following command your can compute the metric of Recall.

python compute_recall.py
