Relation as a Prior: A Novel Paradigm for LLM-based Document-level Relation Extraction

arXiv — cs.CL•Wednesday, November 12, 2025 at 5:00:00 AM

Recent advancements in Large Language Models (LLMs) have showcased their potential in document understanding, yet challenges remain, particularly in Document-level Relation Extraction (DocRE). Traditional methods often falter due to noise from unrelated entity pairs and misclassification of relation labels. To address these issues, the 'Relation as a Prior' (RelPrior) paradigm has been proposed, which strategically utilizes binary relations to filter out irrelevant entities and enhance the accuracy of relation predictions. Extensive experiments conducted on two benchmarks demonstrate that RelPrior not only mitigates the performance gaps identified in LLMs but also achieves state-of-the-art results, surpassing existing methods. This development is crucial as it paves the way for more effective document analysis, potentially transforming applications in various fields such as information retrieval and natural language processing.

Silenced Biases: The Dark Side LLMs Learned to Refuse

NegativeArtificial Intelligence

Safety-aligned large language models (LLMs) are increasingly used in sensitive applications where fairness is crucial. Evaluating their fairness is complex, often relying on standard question-answer schemes that may misinterpret refusal responses as indicators of fairness. This paper introduces the concept of silenced biases, which are unfair preferences hidden within the models' latent space, masked by safety-alignment. Previous methods have limitations, prompting the need for a new approach to assess these biases effectively.

Modeling and Predicting Multi-Turn Answer Instability in Large Language Models

NeutralArtificial Intelligence

The paper titled 'Modeling and Predicting Multi-Turn Answer Instability in Large Language Models' discusses the evaluation of large language models (LLMs) in terms of their robustness during user interactions. The study employs multi-turn follow-up prompts to assess changes in model answers and accuracy dynamics using Markov chains. Results indicate vulnerabilities in LLMs, with a 10% accuracy drop for Gemini 1.5 Flash after a 'Think again' prompt over nine turns, and a 7.5% drop for Claude 3.5 Haiku with a reworded question. The findings suggest that accuracy can be modeled over time.

A Multifaceted Analysis of Negative Bias in Large Language Models through the Lens of Parametric Knowledge

NeutralArtificial Intelligence

A recent study published on arXiv examines the phenomenon of negative bias in large language models (LLMs), which refers to their tendency to generate negative responses in binary decision tasks. The research highlights that previous studies have primarily focused on identifying negative attention heads that contribute to this bias. The authors introduce a new evaluation pipeline that categorizes responses based on the model's parametric knowledge, revealing that the format of prompts significantly influences the responses more than the semantics of the content itself.

Identifying and Analyzing Performance-Critical Tokens in Large Language Models

NeutralArtificial Intelligence

The paper titled 'Identifying and Analyzing Performance-Critical Tokens in Large Language Models' explores how large language models (LLMs) utilize in-context learning (ICL) for few-shot learning. It categorizes tokens in ICL prompts into content, stopword, and template tokens, aiming to identify those that significantly impact LLM performance. The study reveals that template and stopword tokens have a greater influence on performance than informative content tokens, challenging existing assumptions about human attention to informative words.
