Is ChatGPT More Empathetic than Humans?

1 code implementation22 Feb 2024 Anuradha Welivita, Pearl Pu

This paper investigates the empathetic responding capabilities of ChatGPT, particularly its latest iteration, GPT-4, in comparison to human-generated responses to a wide range of emotional scenarios, both positive and negative.

Use of a Taxonomy of Empathetic Response Intents to Control and Interpret Empathy in Neural Chatbots

no code implementations17 May 2023 Anuradha Welivita, Pearl Pu

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.

How Commonsense Knowledge Helps with Natural Language Tasks: A Survey of Recent Resources and Methodologies

no code implementations10 Aug 2021 Yubo Xie, Pearl Pu

In this paper, we give an overview of commonsense reasoning in natural language processing, which requires a deeper understanding of the contexts and usually involves inference over implicit external knowledge.

HumorHunter at SemEval-2021 Task 7: Humor and Offense Recognition with Disentangled Attention

no code implementations SEMEVAL 2021 Yubo Xie, Junze Li, Pearl Pu

The task aims at predicting whether the given text is humorous, the average humor rating given by the annotators, and whether the humor rating is controversial.

Empathetic Dialog Generation with Fine-Grained Intents

1 code implementation CoNLL (EMNLP) 2021 Yubo Xie, Pearl Pu

Empathetic dialog generation aims at generating coherent responses following previous dialog turns and, more importantly, showing a sense of caring and a desire to help.
