Modeling Empathetic Alignment in Conversation (2024.naacl-long)

Copied to clipboard

Challenge: Empathy requires perspective-taking and is not explicitly modelled in NLP .
Approach: They propose a new approach to recognizing alignment in empathetic speech, grounded in Appraisal Theory, and use reddit to study emotional conversations to examine alignment.
Outcome: The proposed approach can recognize appraisals and alignments in empathetic speech, and mental health professionals engage with substantially more emotional alignment.

CASE: Aligning Coarse-to-Fine Cognition and Affection for Empathetic Response Generation (2023.acl-long)

Copied to clipboard

Challenge: Existing empathetic dialogue models only consider the affective aspect of empathy, which limits the capability of emotional response generation.
Approach: They propose a model that aligns the user's cognition and affection at both the coarse-grained and fine-grounded levels and then automatically and manually evaluates the model.
Outcome: The proposed model outperforms state-of-the-art models and generates more empathetic and informative responses.
Towards Empathetic Open-domain Conversation Models: A New Benchmark and Dataset (P19-1)

Challenge: EmpatheticDialogues dataset provides a benchmark for empathetic dialogue generation . human evaluators perceive dialogue models as more epathetic .
Approach: They propose a benchmark for empathetic dialogue generation from a dataset of 25k conversations grounded in emotional situations.
Outcome: The proposed benchmarks show that existing models are perceived to be more empathetic by human evaluators compared to models trained on large-scale Internet conversations.
Empathy Identification Systems are not Accurately Accounting for Context (2023.eacl-main)

Copied to clipboard

Challenge: Empathy is a fundamental phenomenon that allows us to better communicate and relate with others.
Approach: They propose a simple model that checks if an input utterance is similar to a small set of empathetic examples, but does not consider dialogue context.
Outcome: The proposed model outperforms state-of-the-art models on benchmarks and empathetic rationale extraction benchmarks.
Multi-dimensional Evaluation of Empathetic Dialogue Responses (2024.findings-emnlp)

Copied to clipboard

Challenge: Prior efforts to measure conversational empathy focus on expressed communicative intents, but ignore the fact that conversation is also a collaboration involving both speakers and listeners.
Approach: They propose a multi-dimensional empathy evaluation framework to measure both expressed intents from the speaker’s perspective and perceived empathy from the listener’s viewpoint.
Outcome: The proposed framework measures both expressed intents from the speaker’s perspective and perceived empathy from the listener’s viewpoint.
REG: Retrieval via Emotion Similarity for Guiding Empathetic Dialogue Generation (2026.acl-long)

Copied to clipboard

Challenge: Empathy relies on the cognitive capacity to relate to similar past experiences. Existing methods prioritize semantic similarity over emotion characteristics, leading to unempathetic responses.
Approach: They propose a framework that integrates four Emotion Attributes into the retrieval process to ensure explicit emotional alignment.
Outcome: Empirical results show that REG significantly outperforms baselines, offering a robust solution for empathetic generation.

Approach: They propose a framework which combines fine-tuned models, large language models, classical dialogue evaluation metrics, and a novel metric.
Outcome: The proposed framework improves on the WASSA 2024 benchmark and shows a statistically significant 8% improvement on the EX dataset.
Can Machines Resonate with Humans? Evaluating the Emotional and Empathic Comprehension of LMs (2024.findings-emnlp)

Copied to clipboard

Challenge: Empathy plays a pivotal role in fostering prosocial behavior, often triggered by the sharing of personal experiences through narratives.
Approach: They propose to use contrastive learning with masked LMs and supervised fine-tuning with large language models to improve empathy understanding in NLP models.
Outcome: The proposed methods show that there is low agreement among annotators and that cultural differences are a factor in their interpretation of empathy.

Challenge: Open-domain conversational agents or chatbots are becoming increasingly popular in the natural language processing community.
Approach: They aim to combine dialogue act/intent modelling and neural response generation to produce a large-scale taxonomy for empathetic response intents.
Outcome: The proposed method improves the response quality of chatbots and makes them more controllable and interpretable.
Constructing Emotional Consensus and Utilizing Unpaired Data for Empathetic Dialogue Generation (2021.findings-emnlp)

Copied to clipboard

Challenge: Existing models for dialogue empathy focus on the emotion flow in one direction, from context to response.
Approach: They propose a dual-generative model to construct emotional consensus and use unpaired data to produce pseudo paired empathetic samples.
Outcome: The proposed model outperforms baseline models in producing coherent and empathetic responses.
Harnessing the Power of Large Language Models for Empathetic Response Generation: Empirical Investigations and Improvements (2023.findings-emnlp)

Copied to clipboard

Challenge: Empathetic dialogue is an essential part of building harmonious social relationships and contributes to the development of a helpful AI.
Approach: They propose three methods to improve the performance of large language models (LLMs) they propose semantically similar in-context learning, two-stage interactive generation and combination with the knowledge base.
Outcome: The proposed methods achieve state-of-the-art in automatic and human evaluations and the possibility of GPT-4 simulating human evaluators.
