LLM Targeted Underperformance Disproportionately Impacts Vulnerable Users

AAAI 2026technical

While state-of-the-art large language models (LLMs) have shown impressive performance on many tasks, systematically evaluating undesirable behaviors of these models remains critical. In this work, we investigate how the quality of LLM responses changes in terms of information accuracy, truthfulness,

Bridging Context Gaps: Enhancing Comprehension in Long-Form Social Conversations Through Contextualized Excerpts

COLING 2025main

We focus on enhancing comprehension in small-group recorded conversations, which serve as a medium to bring people together and provide a space for sharing personal stories and experiences on crucial social matters. One way to parse and convey information from these conversations is by sharing highl…

Computational Analysis of Conversation Dynamics through Participant Responsivity

EMNLP 2025

Growing literature explores toxicity and polarization in discourse, with comparatively less work on characterizing what makes dialogue prosocial and constructive. We explore conversational discourse and investigate a method for characterizing its quality built upon the notion of “responsivity”—wheth

Just Put a Human in the Loop? Investigating LLM-Assisted Annotation for Subjective Tasks

ACL 2025finding

LLM use in annotation is becoming widespread, and given LLMs’ overall promising performance and speed, putting humans in the loop to simply “review” LLM annotations can be tempting. In subjective tasks with multiple plausible answers, this can impact both evaluation of LLM performance, and analysis…

Leveraging Large Language Models for Learning Complex Legal Concepts through Storytelling

ACL 2024long

Making legal knowledge accessible to non-experts is crucial for enhancing general legal literacy and encouraging civic participation in democracy. However, legal documents are often challenging to understand for people without legal backgrounds. In this paper, we present a novel application of large…

On the Relationship between Truth and Political Bias in Language Models

EMNLP 2024main

Language model alignment research often attempts to ensure that models are not only helpful and harmless, but also truthful and unbiased. However, optimizing these objectives simultaneously can obscure how improving one aspect might impact the others. In this work, we focus on analyzing the relation…

PersonaLLM: Investigating the Ability of Large Language Models to Express Personality Traits

NAACL 2024findings

Despite the many use cases for large language models (LLMs) in creating personalized chatbots, there has been limited research on evaluating the extent to which the behaviors of personalized LLMs accurately and consistently reflect specific personality traits. We consider studying the behavior of LL…

Topic Detection and Tracking with Time-Aware Document Embeddings

COLING 2024main

The time at which a message is communicated is a vital piece of metadata in many real-world natural language processing tasks such as Topic Detection and Tracking (TDT). TDT systems aim to cluster a corpus of news articles by event, and in that context, stories that describe the same event are likel…

M-sense: Modeling Narrative Structure in Short Personal Narratives Using Protagonist’s Mental Representations

AAAI 2023technical

Narrative is a ubiquitous component of human communication. Understanding its structure plays a critical role in a wide variety of applications, ranging from simple comparative analyses to enhanced narrative retrieval, comprehension, or reasoning capabilities. Prior research in narratology has highl…

CommunityLM: Probing Partisan Worldviews from Language Models

COLING 2022main

As political attitudes have diverged ideologically in the United States, political speech has diverged lingusitically. The ever-widening polarization between the US political parties is accelerated by an erosion of mutual understanding between them. We aim to make these communities more comprehensib…
