A Critical Reflection and Forward Perspective on Empathy and Natural Language Processing (2022.findings-emnlp)

Copied to clipboard

Challenge: Empathy recognition and empathetic response generation tasks are well-established research directions, but there is little clarity on what empathy is and how it is being operationalized.
Approach: They argue that current directions will benefit from a clear conceptualization that includes operationalizing cognitive empathy components.
Outcome: The proposed framework will help to define and operationalize empathy in natural language processing.
