TLDR: The research introduces SENSE-7, a human-centered taxonomy and dataset for evaluating user-perceived empathy in human-AI conversations. It defines seven observable empathic behaviors and analyzes 695 real-world conversations, revealing that empathy judgments are highly subjective, context-sensitive, and significantly impacted by conversational continuity. The study emphasizes tailoring AI’s empathic responses to individual user needs and contexts, moving beyond mere simulation of internal emotional states.
Empathy is a cornerstone of human communication, fostering trust and understanding in our relationships. As artificial intelligence, particularly Large Language Models (LLMs), becomes increasingly integrated into our daily lives, the concept of “digital empathy” has gained significant attention. However, traditional approaches to AI empathy often focus on making AI simulate human-like emotions, overlooking the crucial aspect of how users actually perceive empathy in these interactions.
A recent research paper, SENSE-7: Taxonomy and Dataset for Measuring User Perceptions of Empathy in Sustained Human-AI Conversations, by Jina Suh, Lindy Le, Erfan Shayegani, Gonzalo Ramos, Judith Amores, Desmond C. Ong, Mary Czerwinski, and Javier Hernandez, addresses this gap by proposing a human-centered framework for understanding and measuring empathy in human-AI conversations. This work shifts the focus from AI’s internal states to observable empathic behaviors as perceived by users.
A New Framework for Digital Empathy
The researchers introduce a multidimensional taxonomy that reframes traditional psychological concepts of empathy into seven observable behaviors for AI agents. These dimensions are:
- Affective Understanding: The AI’s ability to accurately recognize and understand a user’s emotional state.
- Cognitive Understanding: The AI’s capacity to comprehend the user’s perspective, intentions, and mental states.
- Response Appropriateness: The AI’s skill in generating adaptive and context-sensitive responses, knowing when to listen, validate, or offer advice.
- Prosocial Expression: The AI’s demonstration of a desire to help and care for the user, showing supportive and kind actions.
- Interest: The AI’s active engagement and curiosity in the ongoing interaction, including asking clarifying questions.
- Contextual Understanding: The AI’s ability to integrate the user’s broader background, such as personal history, cultural context, and preferences, into the conversation.
- Relational Continuity: The AI’s capacity to maintain and enrich the relationship by consistently recalling details from past interactions.
To support this taxonomy, the team developed SENSE-7, a new dataset of real-world conversations between information workers and LLMs. This dataset includes per-turn empathy annotations directly from the users, along with user characteristics and contextual details, providing a rich, user-grounded representation of empathy.
Key Findings from Real-World Conversations
The study analyzed 695 conversations from 109 participants, revealing several important insights:
- Subjectivity and Context: Empathy judgments are highly individualized and context-sensitive. Factors like a user’s age, attitude towards AI, and the topic of conversation (e.g., personal issues vs. information tasks) significantly influence their perception of empathy.
- Impact of “Poor” Turns: Even a single perceived “poor” turn in a conversation can substantially diminish a user’s overall empathy rating and lead to lower engagement. This highlights the critical importance of consistent empathic behavior throughout an interaction.
- Valued Dimensions: Users particularly value cognitive understanding and response appropriateness. While affective understanding is important, the ability of the AI to truly grasp the user’s intent and respond in a tactful, relevant manner is often seen as a differentiating factor from a simple search engine.
- GPT4-empathy Performance: Among the four LLM-based systems tested (GPT-4, GPT-4-empathy, Llama2-70b, and IC), the GPT4-empathy model, which was specifically designed with a system prompt to encourage empathic responses based on the seven dimensions, received the highest overall empathy ratings. This suggests that explicit design for multidimensional empathy can be effective.
- Unspoken Expectations: Participants often had implicit expectations or desired responses that they didn’t explicitly state. When these unspoken needs were not met, it led to lower empathy ratings, underscoring the need for AI to proactively establish shared understanding through clarifying questions.

Implications for Future AI Design
The findings underscore the need for AI designs that can dynamically tailor empathic behaviors to individual user contexts and goals. This involves:
- Dynamic Empathy Calibration: AI systems should adapt the level and type of empathy in real-time based on user characteristics (e.g., emotional regulation skills) and situational factors (e.g., conversation topic, mood).
- Multi-Turn Continuity and Repair Strategies: AI should be optimized to maintain continuity across multiple turns, remembering past details, and employing repair strategies when empathic breakdowns occur. Generic or list-based responses, especially when unsolicited, can be detrimental.
- Human-Centered Measurement: Collecting subjective, per-turn feedback directly from users provides a more accurate and nuanced understanding of perceived empathy than generalized, third-party annotations.
While the study also explored automatic classification of perceived empathy, achieving true empathic resonance remains a complex challenge. The research advocates for a flexible, iterative, and interactional framework for digital empathy, paving the way for AI agents that are genuinely supportive and socially attuned to diverse user needs.
