Intent-Aware Schema Generation And Refinement For Literature Review Tables

Vishakh PadmakumarJoseph Chee ChangKyle LoAakanksha Naik
2025
EMNLP

The increasing volume of academic literature makes it essential for researchers to organize, compare, and contrast collections of documents. Large language models (LLMs) can support this process by… 

Text or Pixels? It Takes Half: On the Token Efficiency of Visual Text Inputs in Multimodal LLMs

Yanhong LiZixuan LanJiawei Zhou
2025
EMNLP

Large language models (LLMs) and their multimodal variants can now process visual inputs, including images of text. This raises an intriguing question: can we compress textual inputs by feeding them… 

MoNaCo: More Natural and Complex Questions for Reasoning Across Dozens of Documents

Tomer WolfsonHarsh TrivediMor GevaReut Tsarfaty
2025
TACL

Automated agents, powered by Large language models (LLMs), are emerging as the go-to tool for querying information. However, evaluation benchmarks for LLM agents rarely feature natural questions… 

AstaBench: Rigorous Benchmarking of AI Agents with a Scientific Research Suite

Jonathan BraggMike D'ArcyNishant BalepurDaniel S. Weld
2025
arXiv

AI agents hold great real-world promise, with the potential to revolutionize scientific productivity by automating literature reviews, replicating experiments, analyzing data, and even proposing new… 

On the Reasoning Abilities of Masked Diffusion Language Models

Anej SveteAshish Sabharwal
2025
ICLR

Masked diffusion models (MDMs) for text offer a compelling alternative to traditional autoregressive language models. Parallel generation makes them efficient, but their computational capabilities… 

Aligning LLMs to Ask Good Questions A Case Study in Clinical Reasoning

Shuyue Stella LiJimin MunFaeze BrahmanMaarten Sap
2025
COLM

Large language models (LLMs) often fail to ask effective questions under uncertainty, making them unreliable in domains where proactive information-gathering is essential for decisionmaking. We… 

HAICOSYSTEM: An Ecosystem for Sandboxing Safety Risks in Human-AI Interactions

Xuhui ZhouHyunwoo KimFaeze BrahmanMaarten Sap
2025
COLM

AI agents are increasingly autonomous in their interactions with human users and tools, leading to increased interactional safety risks. We present HAICOSYSTEM, a framework examining AI agent safety… 

ParaPO: Aligning Language Models to Reduce Verbatim Reproduction of Pre-training Data

Tong ChenFaeze BrahmanJiacheng LiuHanna Hajishirzi
2025
COLM

Language models (LMs) can memorize and reproduce segments from their pretraining data verbatim even in non-adversarial settings, raising concerns about copyright, plagiarism, privacy, and…
