This position paper presents a novel perspective on the utilization of Large Language Models (LLMs) in the artificial intelligence paper review process. We first critique the current tendency for LLMs to be primarily used for simple review text generation, arguing instead that this approach overlooks more meaningful applications of LLMs that preserve human expertise at the core of evaluation. Instead, we advocate for leveraging LLMs to support key aspects of the review processвЂ”specifically, verifying the reproducibility of experimental results, checking the correctness and relevance of citations, and assisting with ethics review flagging. For example, integrating tools based on LLM Agents for code generation from research papers has recently enabled automated assessment of the reproducibility of the paper, thereby improving the transparency and reliability of research. By reorienting LLM usage toward these targeted and assistive roles, we outline a pathway for more effective and responsible integration of LLMs into peer review, ultimately supporting both reviewer efficiency and the integrity of the scientific process.

Welcome to the 19th Conference of the European Chapter of the Association for Computational Linguistics (EACL). EACL 2026 will be held in Rabat, Morocco, from March 24–29, 2026. 

Large Language Models (LLMs) display remarkable capabilities to understand or even produce political discourse, but have been found to consistently display a progressive left-leaning bias. At the same time, so-called persona or identity prompts have been shown to produce LLM behavior that aligns with socioeconomic groups that the base model is not aligned with. In this work, we analyze whether zero-shot persona prompting with limited information can accurately predict individual voting decisions and, by aggregation, accurately predict positions of European groups on a diverse set of policies. We evaluate if predictions are stable towards counterfactual arguments, different persona prompts and generation methods. Finally, we find that we can simulate voting behavior of Members of the European Parliament reasonably well with a weighted F1 score of approximately 0.793. Our persona dataset of politicians in the 2024 European Parliament and our code are available at https://anonymous.4open.science/r/european_parliament_simulation-7285.

General-purpose Large Language Models (LLMs) are frequently fine-tuned through supervised fine-tuning (SFT) to enhance performance in specific domains. Better results can be achieved by distilling the chain-of-thought of a larger model at the cost of numerous expensive calls and a much greater amount of data. We propose a novel blueprint for efficient fine-tuning that uses reasoning only for complex data identified by entropy. Specifically, across three small open models (3B) we split the training data into complexity categories by a single token answer entropy (ROC AUC 0.73), fine-tune large language models (LLMs) via SFT and distillation, and show that our pipeline significantly outperforms the standard SFT approach (0.58 vs 0.45 average accuracy) and outperforms the distillation approach (0.58 vs 0.56 average accuracy) while using 81% less data. We publish our code and data to facilitate further research in this direction.

Complexity-aware fine-tuning

We propose a novel K -step return estimation method (called K ETCHUP) for Reinforcement Learning (RL)-based knowledge distillation (KD) in text generation tasks. Our idea is to induce a K -step return by using the Bellman Optimality Equation for multiple steps. Theoretical analysis shows that this K -step formulation reduces the variance of the gradient estimates, thus leading to improved RL optimization, especially when the student model size is large. Empirical evaluation on three text generation tasks demonstrates that our approach yields superior performance in both standard task metrics and large language model (LLM)-based evaluation. These results suggest that our K -step return induction offers a promising direction for enhancing RL-based KD in LLM research.

KETCHUP: KK-Step Return Estimation for Sequential Knowledge Distillation

This paper discusses the internal behavior of Transformer language models. Many recent pre-trained models have been reported to exhibit only slight changes in the angular distance between input and output hidden state vectors in the middle Transformer layers, despite a disproportionately large ``jump'' in angular distance occurring in or around the final Transformer layer. To characterize this, we first introduce a quantitative metric for jump strength around the final layer, and then demonstrate its prevalence across many public pre-trained models, as well as its amplification throughout pre-training. Assuming such jumps indicate an undesirable property, we propose a regularizer that penalizes the jump during pre-training, thereby encouraging more balanced capability usage across the middle layers. Empirical evaluations of three model sizes of Llama-based models, trained with our jump-suppressing regularizer (JREG), reveal improved task performance compared to the baseline without altering the model architecture.

Suppressing Final Layer Hidden State Jumps in Transformer Pretraining

With the increasing adoption of Large Language Models (LLMs) and Vision-Language Models (VLMs), rich document analysis technologies for applications like Retrieval-Augmented Generation (RAG) and visual RAG are gaining significant attention. Recent research indicates that using VLMs yields better RAG performance, but processing rich documents remains a challenge since a single page contains large amounts of information. In this paper, we present SCAN (SemantiC Document Layout ANalysis), a novel approach that enhances both textual and visual Retrieval-Augmented Generation (RAG) systems that work with visually rich documents. It is a VLM-friendly approach that identifies document components with appropriate semantic granularity, balancing context preservation with processing efficiency. SCAN uses a coarse-grained semantic approach that divides documents into coherent regions covering contiguous components. We trained the SCAN model by fine-tuning object detection models on an annotated dataset. Our experimental results across English and Japanese datasets demonstrate that applying SCAN improves end-to-end textual RAG performance by up to 9.4 points and visual RAG performance by up to 10.4 points, outperforming conventional approaches and even commercial document processing solutions.

Recent advancements in LLMs have significantly improved mathematical problem-solving, with models like GPT-4 achieving human-level performance. However, proficiently solving mathematical problems differs fundamentally from effectively teaching mathematics. To bridge this gap, we introduce the Bi-GSM8K benchmark, a bilingual English-Korean dataset enriched with teacher solutions, student solutions, and annotations marking students' initial errors. This dataset is designed to evaluate two core capabilities of LLMs: (1) measuring similarity between student and teacher solutions, and (2) identifying the initial error point in student solutions. Our method achieves high agreement with human judgments, with Pearson 0.89 and Spearman 0.88 on English, and Pearson 0.89 and Spearman 0.87 on Korean. It also offers significantly lower latency and resource usage than commercial APIs, demonstrating strong computational efficiency. In the error detection task, open-source models achieved approximately 86% accuracy, with performance within 10% points of commercial LLMs API, suggesting strong practical potential. Our key contributions include the open-source release of Bi-GSM8K, novel evaluation metrics, and comparative analyses of LLM performance across languages.

Beyond Accuracy: Alignment and Error Detection across Languages in the Bi-GSM8K Math-Teaching Benchmark

In conversation, humans use multimodal cues, such as speech, gestures, and gaze, to manage turn-taking. While linguistic and acoustic features are informative, gestures provide complementary cues for modeling these transitions. To study this, we introduce DnD Gesture++, an extension of the multi-party DnD Gesture corpus enriched with 2,663 semantic gesture annotations spanning iconic, metaphoric, deictic, and discourse types. Using this dataset, we model turn-taking prediction through a Mixture-of-Experts framework integrating text, audio, and gestures. Experiments show that incorporating semantically guided gestures yields consistent performance gains over baselines, demonstrating their complementary role in multimodal turn-taking.

Modeling Turn-Taking with Semantically Informed Gestures

Reasoning in language models is difficult to evaluate: natural-language traces are unverifiable, symbolic datasets too small, and most benchmarks conflate heuristics with inference. We present FOL-Traces, the first large-scale dataset of programmatically verified reasoning traces, enabling rigorous evaluation of structured logical inference. We also propose two challenging and comprehensive diagnostic tasks---masked operation prediction and step completion---that directly probe syntactic awareness and process fidelity. FOL-Traces serves as a scalable testbed for rigorously studying how models perform structured logical inference. Systematic experiments with 5 reasoning LLMs show that the dataset remains challenging: models only reach around 45.7% accuracy on masked operation prediction and around 27% on two-step completion.

FOL-Traces: Verified First-Order Logic Reasoning Traces at Scale

Large language models suffer from positional biases like the "Lost in the Middle'" (LiM) phenomenon and recency bias, which undermine the performance of long-context retrieval augmented generation. In this work, we investigate the role of rotary position embeddings (RoPE) in this context. Our empirical study confirms the persistence of these biases in modern language models. Drawing on these findings, we introduce Caliope, a training-free calibration framework for modifying RoPE inputs at inference time. Our calibrators yield substantial improvements in specific model-task configurations, revealing complex performance trade-offs between simple needle-in-a-haystack experiments and more demanding cross-chunk reasoning tasks. This work offers a practical mitigation framework and key insights into the nature of positional biases.

Can Calibration of Positional Encodings Enhance Long Context Utilization?

Modern language models excel at factual reasoning but struggle with value diversity: the multiplicity of plausible human perspectives. Tasks such as hate speech or sexism detection expose this limitation, where human disagreement captures the diversity of perspectives that models need to account for, rather than dataset noise. In this paper, we explore whether multi-perspective in-context learning (ICL) can align large language models (LLMs) with this diversity without parameter updates. We evaluate four LLMs on five datasets across three languages (English, Arabic, Italian), considering three label-space representations (aggregated hard, disaggregated hard, and disaggregated soft) and five demonstration selection and ordering strategies. Our multi-perspective approach outperforms standard prompting on aggregated English labels, while disaggregated soft predictions better align with human judgments in Arabic and Italian datasets.These findings highlight the importance of perspective-aware LLMs for reducing bias and polarization, while also revealing the challenges of applying ICL to socially sensitive tasks. We further probe the model faithfulness using XAI, offering insights into how LLMs handle human disagreement.
