ToMStories: Interpreting Theory-of-Mind in Synthetic Narratives

Melanie Subbiah, Chia-En Jacklyn Tsai, Kathleen McKeown

Understanding people often requires inferring what they feel or want from how they behave rather than from what they state outright. We ask whether language models can make these i…

Empath: Tracing Multi-Level Emotion Dynamics in Crisis Counseling Dialogues

Ziwei Gong, Yuchen Huang, Wen Liang +4

Emotion dynamics are critical for understanding crisis-support conversations, yet most computational work treats emotion as static utterance-level labels. We introduce EMPATH, a fr…

On the Limits of Steering Vectors for Preference-Aligned Generation

Melanie Subbiah, Zara Hall, Kathleen McKeown

Steering vectors have emerged as a promising approach to controlled text generation, offering interpretable, training-free mechanisms for shaping model outputs. However, their prac…

Detect, Remask, Repair: Diffusion Editing for Faithful Summarization of Evolving Contexts

Hao Zou, Zachary Horvitz, Chandhru Karthick +2

Summaries of real-world events can become outdated as contexts evolve and new information arrives. A common response is to generate a new summary from the updated context, but full…

Whose Story Gets Told? Positionality and Bias in LLM Summaries of Life Narratives

Melanie Subbiah, Haaris Mian, Nicholas Deas +3

Increasingly, studies are exploring using Large Language Models (LLMs) for accelerated or scaled qualitative analysis of text data. While we can compare LLM accuracy against human…

Artificial Impressions: Evaluating Large Language Model Behavior Through the Lens of Trait Impressions

Nicholas Deas, Kathleen McKeown

We introduce and study artificial impressions--patterns in LLMs' internal representations of prompts that resemble human impressions and stereotypes based on language. We fit linea…

AdvSumm: Adversarial Training for Bias Mitigation in Text Summarization

Mukur Gupta, Nikhil Reddy Varimalla, Nicholas Deas +2

Large Language Models (LLMs) have achieved impressive performance in text summarization and are increasingly deployed in real-world applications. However, these systems often inher…

Counterfactual Simulatability of LLM Explanations for Generation Tasks

Marvin Limpijankit, Yanda Chen, Melanie Subbiah +2

LLMs can be unpredictable, as even slight alterations to the prompt can cause the output to change in unexpected ways. Thus, the ability of models to accurately explain their behav…
