• $\mathcal{S}^2$IT: Stepwise Syntax Integration Tuning for Large Language Models in Aspect Sentiment Quad Prediction

  Bingfeng Chen, Chenjie Qiu, Yifeng Xie, Boyan Xu, Ruichu Cai, Zhifeng Hao · 29 avril 2026

  Aspect Sentiment Quad Prediction (ASQP) has seen significant advancements, largely driven by the powerful semantic understanding and generative capabilities of large language models (LLMs). However, while syntactic structure information has been proven effective in previous extractive paradigms, it …

• Two-dimensional early exit optimisation of LLM inference

  Jan H\r{u}la, David Adamczyk, Tom\'a\v{s} Filip, Martin Pavl\'i\v{c}ek, Petr Sos\'ik · 22 avril 2026

  We introduce a two-dimensional (2D) early exit strategy that coordinates layer-wise and sentence-wise exiting for classification tasks in large language models. By processing input incrementally sentence-by-sentence while progressively activating deeper layers, our method achieves multiplicative com…

• Consistency Analysis of Sentiment Predictions using Syntactic & Semantic Context Assessment Summarization (SSAS)

  Sharookh Daruwalla, Nitin Mayande, Shreeya Verma Kathuria, Nitin Joglekar, Charles Weber · 20 avril 2026

  The fundamental challenge of using Large Language Models (LLMs) for reliable, enterprise-grade analytics, such as sentiment prediction, is the conflict between the LLMs' inherent stochasticity (generative, non-deterministic nature) and the analytical requirement for consistency. The LLM inconsistenc…

• When Missing Becomes Structure: Intent-Preserving Policy Completion from Financial KOL Discourse

  Yuncong Liu, Yuan Wan, Zhou Jiang, Yao Lu · 17 avril 2026

  Key Opinion Leader (KOL) discourse on social media is widely consumed as investment guidance, yet turning it into executable trading strategies without injecting assumptions about unspecified execution decisions remains an open problem. We observe that the gaps in KOL statements are not random defic…

• Decoupling Scores and Text: The Politeness Principle in Peer Review

  Yingxuan Wen · 17 avril 2026

  Authors often struggle to interpret peer review feedback, deriving false hope from polite comments or feeling confused by specific low scores. To investigate this, we construct a dataset of over 30,000 ICLR 2021-2025 submissions and compare acceptance prediction performance using numerical scores ve…

• From Prediction to Justification: Aligning Sentiment Reasoning with Human Rationale via Reinforcement Learning

  Shihao Zhang, Ziwei Wang, Jie Zhou, Yulan Wu, Qin Chen, Zhikai Lei, Liyang Yu, Liang Dou, Liang He · 16 avril 2026

  While Aspect-based Sentiment Analysis (ABSA) systems have achieved high accuracy in identifying sentiment polarities, they often operate as "black boxes," lacking the explicit reasoning capabilities characteristic of human affective cognition. Humans do not merely categorize sentiment; they construc…

• Beyond Factual Grounding: The Case for Opinion-Aware Retrieval-Augmented Generation

  Aditya Agrawal, Alwarappan Nakkiran, Darshan Fofadiya, Alex Karlsson, Harsha Aduri · 15 avril 2026

  RAG systems have transformed how LLMs access external knowledge, but we find that current implementations exhibit a bias toward factual, objective content, as evidenced by existing benchmarks and datasets that prioritize objective retrieval. This factual bias - treating opinions and diverse perspect…

• C2F-Thinker: Coarse-to-Fine Reasoning with Hint-Guided Reinforcement Learning for Multimodal Sentiment Analysis

  Miaosen Luo, Zhenhao Yang, Jieshen Long, Jinghu Sun, Yichu Liu, Sijie Mai · 14 avril 2026

Despite the progress of multimodal large language models (MLLMs) via supervised fine-tuning, their "black-box" nature hinders interpretability. While Chain-of-Thought (CoT) rea…

• GLEaN: A Text-to-image Bias Detection Approach for Public Comprehension

  Bochu Ding, Brinnae Bent, Augustus Wendell · 14 avril 2026

  Text-to-image (T2I) models, and their encoded biases, increasingly shape the visual media the public encounters. While researchers have produced a rich body of work on bias measurement, auditing, and mitigation in T2I systems, those methods largely target technical stakeholders, leaving a gap in pub…

• LOLGORITHM: Funny Comment Generation Agent For Short Videos

  Xuan Ouyang, Senan Wang, Bouzhou Wang, Siyuan Xiahou, Jinrong Zhou, Yuekang Li · 14 avril 2026
