Papers by Nicholas Beauchamp
MOKA: Moral Knowledge Augmentation for Moral Event Extraction (2024.naacl-long)
Copied to clipboard
| Challenge: | Existing methods for discerning moral values are limited due to lack of context, lack of moral reasoning capabilities and complexity of moral stances. |
| Approach: | They propose a framework for moral event extraction using moral words and moral scenarios. |
| Outcome: | The proposed framework outperforms baselines across three moral event understanding tasks. |
Narrative-of-Thought: Improving Temporal Reasoning of Large Language Models via Recounted Narratives (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Large language models (LLMs) have demonstrated impressive performance in many reasoning tasks, but temporal reasoning remains challenging due to its intrinsic complexity. |
| Approach: | They propose a new prompting technique tailored for temporal reasoning, Narrative-of-Thought (NoT), that first converts the events set to a Python class, then prompts a small model to generate a temporal narrative. |
| Outcome: | The proposed technique achieves the highest F1 on Schema-11 evaluation set, while securing an overall F1 of par with GPT-3.5/4. |
All Things Considered: Detecting Partisan Events from News Media with Cross-Article Comparison (2023.emnlp-main)
Copied to clipboard
| Challenge: | a recent study shows that media influence opinion via the inclusion or omission of partisan events. |
| Approach: | They develop a latent variable-based framework to predict the ideology of news articles by comparing multiple articles on the same story and identifying partisan events whose inclusion or omission reveals ideology. |
| Outcome: | The proposed framework validates the existence of partisan event selection and detects partisan events and article ideology better than baselines. |
Crossing the Aisle: Unveiling Partisan and Counter-Partisan Events in News Reporting (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Prior work in NLP has only studied media bias via linguistic style and word usage. |
| Approach: | They annotate a dataset containing 8,511 (counter-)partisan event annotations in 304 news articles from ideologically diverse media outlets. |
| Outcome: | The proposed dataset contains 8,511 (counter-)partisan event annotations in 304 news articles from ideologically diverse media outlets. |
Microblog Conversation Recommendation via Joint Modeling of Topics and Discourse (N18-1)
Copied to clipboard
| Challenge: | Existing methods for recommendation focus on content of individual posts, but we exploit both context and user content and behavior preferences. |
| Approach: | They propose a method that captures conversational context and user content and behavior preferences. |
| Outcome: | The proposed method outperforms methods that only model content without considering discourse on two Twitter datasets. |
PRIME: Large Language Model Personalization with Cognitive Dual-Memory and Personalized Thought Process (2025.emnlp-main)
Copied to clipboard
| Challenge: | Large language model (LLM) personalization aims to align outputs with individuals’ unique preferences and opinions. |
| Approach: | They integrate a cognitive dual-memory model into LLM personalization by mirroring episodic memory to historical user engagements and semantic memory to long-term, evolving user beliefs. |
| Outcome: | The proposed framework integrates the well-established cognitive dual-memory model into LLM personalization, using episodic and semanticmemories. |
POLITICS: Pretraining with Same-story Article Comparison for Ideology Prediction and Stance Detection (2022.findings-naacl)
Copied to clipboard
| Challenge: | a lack of general-purpose tools to characterize and predict ideology across genres of text remains a challenge . a recent study compared ideology-driven pretraining tasks with long or formal written texts . |
| Approach: | They propose to use a large-scale dataset to train pretraining models that compare political news articles on the same story written by different ideologies. |
| Outcome: | The proposed model outperforms baseline models and state-of-the-art models on ideology prediction and stance detection tasks. |
