- Title: Use of a Taxonomy of Empathetic Response Intents to Control and
Interpret Empathy in Neural Chatbots
- Authors: Anuradha Welivita and Pearl Pu
- Abstract summary: 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.

- Abstract: 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. But empathy is a broad concept that
refers to the cognitive and emotional reactions of an individual to the
observed experiences of another and it is more complex than mere mimicry of
emotion. Hence, it requires identifying complex human conversational strategies
and dynamics in addition to generic emotions to control and interpret
empathetic responding capabilities of chatbots. In this work, we make use of a
taxonomy of eight empathetic response intents in addition to generic emotion
categories in building a dialogue response generation model capable of
generating empathetic responses in a controllable and interpretable manner. It
consists of two modules: 1) a response emotion/intent prediction module; and 2)
a response generation module. 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. Automatic and human evaluation
results emphasize the importance of the use of the taxonomy of empathetic
response intents in producing more diverse and empathetically more appropriate
responses than end-to-end models.

Empathetic response generation endeavors to empower dialogue systems to perceive speakers' emotions and generate empathetic responses accordingly.
We propose Combining Trait and State emotions for Empathetic Response Model (CTSM)
To sufficiently perceive emotions in dialogue, we first construct and encode trait and state emotion embeddings.
We further enhance emotional perception capability through an emotion guidance module that guides emotion representation.

We propose a novel emotion correlation enhanced empathetic dialogue generation framework.
Specifically, a multi-resolution emotion graph is devised to capture context-based emotion interactions.
We then propose an emotion correlation enhanced decoder, with a novel correlation-aware aggregation and soft/hard strategy.

Empathetic dialogue is a human-like behavior that requires the perception of both affective factors (e.g., emotion status) and cognitive factors (e.g., cause of the emotion)
We propose an emotion cause transition graph to explicitly model the natural transition of emotion causes between two adjacent turns in empathetic dialogue.
With this graph, the concept words of the emotion causes in the next turn can be predicted and used by a specifically designed concept-aware decoder to generate the empathic response.

The goal of empathetic response generation is to enhance the ability of dialogue systems to perceive and express emotions in conversations.
We propose a novel empathetic response generation model that can consider multiple state information including emotions and intents simultaneously.
Experimental results show that dynamically managing different information can help the model generate more empathetic responses.

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.

Focused on Emotion Causes [50.569762345799354]
We argue that two issues must be tackled at the same time: (i) identifying which word is the cause for the other's emotion from his or her utterance and (ii) reflecting those specific words in the response generation.
Taking inspiration from social cognition, we leverage a generative estimator to infer emotion cause words from utterances with no word-level label.

We propose an approach that relies on exemplars to cue the generative model on fine stylistic properties that signal empathy to the interlocutor.
We empirically show that these approaches yield significant improvements in empathetic response quality in terms of both automated and human-evaluated metrics.
