This repo contains the implementation of the two papers:
Automatic dialogue generation with expressed emotions
Generating Responses Expressing Emotion in an Open-domain Dialogue System
The second paper is basically an extension of the first, it shows four more approaches to express specified emotions.
The following figure shows an overview of all the 7 models.
The code is originally written in PyTorch0.3 and Python3.6
This project is heavily relying on emotion classifier. In this code ,we use a very simple Bi-LSTM model. The performance would very but not too much depending what kinda of text classifier you are using.
CBET dataset can be accessed through this link. It is balanced in single labeled emotions and preprocessed.
To replicate the results in the paper, you need to follow the following instructions:
-
Firstly, train an emotion classifier using CBET dataset. I used a bi-LSTM.
-
Download jiwei's dataset as in his github page, I made a code that converts his dataset from token IDs to actual tokens.
python jiwei_dataset.py
-
However, there are duplications in the dataset, therefore we need to remove them. I did this by
sortanduniqlinux command line, and there are many alternatives. -
Automaticlaly label the dataset by the classifier.
The procedures are quite simple and I suggest redoing it by better classifiers (E.g. BERT).
Since I am still receiving questions about how to prepare the data, I looked into my old drives and found them. They are now in this Google Drive folder
