Current neural response generation methods rely solely on end-to-end learning from large scale conversation data to generate dialogues.
Recent work has shown the promise of combining dialogue act/intent modelling and neural response generation.

- Abstract: Open-domain conversational agents or chatbots are becoming increasingly
popular in the natural language processing community. One of the challenges is
enabling them to converse in an empathetic manner. Current neural response
generation methods rely solely on end-to-end learning from large scale
conversation data to generate dialogues. This approach can produce socially
unacceptable responses due to the lack of large-scale quality data used to
train the neural models. However, recent work has shown the promise of
combining dialogue act/intent modelling and neural response generation. This
hybrid method improves the response quality of chatbots and makes them more
controllable and interpretable. A key element in dialog intent modelling is the
development of a taxonomy. Inspired by this idea, we have manually labeled 500
response intents using a subset of a sizeable empathetic dialogue dataset (25K
dialogues). Our goal is to produce a large-scale taxonomy for empathetic
response intents. Furthermore, using lexical and machine learning methods, we
automatically analysed both speaker and listener utterances of the entire
dataset with identified response intents and 32 emotion categories. Finally, we
use information visualization methods to summarize emotional dialogue exchange
patterns and their temporal progression. These results reveal novel and
important empathy patterns in human-human open-domain conversations and can
serve as heuristics for hybrid approaches.

Interpret Empathy in Neural Chatbots [4.264192013842096]
A recent trend in the domain of open-domain conversational agents is enabling them to converse empathetically to emotional prompts.
Current approaches either follow an end-to-end approach or condition the responses on similar emotion labels to generate empathetic responses.
We propose several rule-based and neural approaches to predict the next response's emotion/intent and generate responses conditioned on these predicted emotions/intents.

Building open-domain dialogue systems capable of rich human-like conversational ability is one of the fundamental challenges in language generation.
Current work on knowledge-grounded dialogue generation primarily focuses on persona incorporation or searching a fact-based structured knowledge source such as Wikipedia.
Our method takes a broader and simpler approach, which aims to improve the raw conversation ability of the system by mimicking the human response behavior on social media.

Empathetic conversational agents should not only understand what is being discussed, but also acknowledge the implied feelings of the conversation partner.
We propose a method based on a transformer pretrained language model (T5)
We evaluate our model on the EmpatheticDialogues dataset using both automated metrics and human evaluation.

We empirically show that these approaches yield significant improvements in empathetic response quality in terms of both automated and human-evaluated metrics.
