Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: Multimodal Large Language Models (MLLMs) have shown remarkable versatility in understanding diverse multimodal data and tasks. However, these capabilities come with an increased model scale. While post-training pruning reduces model size in unimodal models, its application to MLLMs often yields limited success. Our analysis discovers that conventional methods fail to account for the unique token attributes across layers and modalities inherent to MLLMs. Inspired by this observation, we propose TAMP, a simple yet effective pruning framework tailored for MLLMs, featuring two key components: (1) Diversity-Aware Sparsity, which adjusts sparsity ratio per layer based on diversities among multimodal output tokens, preserving more parameters in high-diversity layers; and (2) Adaptive Multimodal Input Activation, which identifies representative multimodal input tokens using attention scores to guide unstructured weight pruning. We validate our method on two state-of-the-art MLLMs: LLaVA-NeXT, designed for vision-language tasks, and VideoLLaMA2, capable of processing audio, visual, and language modalities. Empirical experiments across various multimodal evaluation benchmarks demonstrate that each component of our approach substantially outperforms existing pruning techniques.

Abstract: Recent years have witnessed rapid advancements in text-to-music generation using large language models, yielding notable outputs. A critical challenge is understanding users with diverse musical expertise and generating music that meets their expectations, an area that remains underexplored.To address this gap, we introduce the novel task of Professional and Amateur Description-to-Song Generation. This task focuses on aligning generated content with human expressions from varying musical proficiency levels, aiming to produce songs that accurately meet auditory expectations and adhere to musical structural conventions. We utilized the MuChin dataset, which contains annotations from both professionals and amateurs for identical songs, as the source for these distinct description types. We also collected a pre-train dataset of over 1.5 million songs; lyrics were included for some, while for others, lyrics were generated using Automatic Speech Recognition (ASR) models.Furthermore, we propose MuDiT/MuSiT, a single-stage framework designed to enhance human-machine alignment in song generation. This framework employs Chinese MuLan (ChinMu) for cross-modal comprehension between natural language descriptions and auditory musical attributes, thereby aligning generated songs with user-defined outcomes. Concurrently, a DiT/SiT model facilitates end-to-end generation of complete songs audio, encompassing both vocals and instrumentation. We proposed metrics to evaluate semantic and auditory discrepancies between generated content and target music. Experimental results demonstrate that MuDiT/MuSiT outperforms baseline models and exhibits superior alignment with both professional and amateur song descriptions.

Abstract: Missing data imputation is a critical challenge in various domains, such as healthcare and finance, where data completeness is vital for accurate analysis. Large language models (LLMs), trained on vast corpora, have shown strong potential in data generation, making them a promising tool for data imputation. However, challenges persist in designing effective prompts for a finetuning-free process and in mitigating biases and uncertainty in LLM outputs. To address these issues, we propose a novel framework, LLM-Forest, which introduces a “forest” of few-shot learning LLM “trees” with their outputs aggregated via confidence-based weighted voting based on LLM self-assessment, inspired by the ensemble learning (Random Forest). This framework is established on a new concept of bipartite information graphs to identify high-quality relevant neighboring entries with both feature and value granularity. Extensive experiments on 9 real-world datasets demonstrate the effectiveness and efficiency of LLM-Forest. The implementation is available at https://github.com/Xinrui17/LLM-Forest
Task Calibration: Calibrating Large Language Models on Inference Tasks
Authors: Yingjie Li; Yun Luo; Xiaotian Xie; Yue Zhang
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: Large language models (LLMs) have exhibited impressive zero-shot performance on inference tasks. However, LLMs may suffer from spurious correlations between input texts and output labels, which limits LLMs’ ability to reason based purely on general language understanding. For example, in the natural language inference (NLI) task, LLMs may make predictions primarily based on premise or hypothesis, rather than both components. To address this problem that may lead to unexpected performance degradation, we propose task calibration (TC), a zero-shot and inference-only calibration method inspired by mutual information which recovers LLM performance through task reformulation. In NLI, TC encourages LLMs to reason based on both premise and hypothesis, while mitigating the models’ over-reliance on individual premise or hypothesis for inference. Experimental results show that TC achieves a substantial improvement on 13 different benchmarks in the zero-shot setup. We further validate the effectiveness of TC in few-shot setups and various natural language understanding tasks. Further analysis indicates that TC is also robust to prompt templates and has the potential to be integrated with other calibration methods. We publicly release our code to facilitate future research.
MiniELM: A Lightweight and Adaptive Query Rewriting Framework for E-Commerce Search Optimization
Authors: Duy A. Nguyen; Rishi Kesav Mohan; Shimeng Yang; Pritom Saha Akash; Kevin Chen-Chuan Chang
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: Query rewriting (QR) is a critical technique in e-commerce search, addressing the lexical gap between user queries and product descriptions to enhance search performance. Existing QR approaches typically fall into two categories: discriminative models and generative methods leveraging large language models (LLMs). Discriminative models often struggle with natural language understanding and offer limited flexibility in rewriting, while generative LLMs, despite producing high-quality rewrites, face high inference latency and cost in online settings. These limitations force offline deployment, making them vulnerable to issues like information staleness and semantic drift. To overcome these challenges, we propose a novel hybrid pipeline for QR that balances efficiency and effectiveness. Our approach combines **offline knowledge distillation** to create a lightweight but efficient student model with **online reinforcement learning (RL)** to refine query rewriting dynamically using real-time feedback. A key innovation is the use of LLMs as **simulated human feedback**, enabling scalable reward signals and cost-effective evaluation without manual annotations. Experimental results on Amazon ESCI dataset demonstrate significant improvements in query relevance, diversity, and adaptability, as well as positive feedback from the LLM simulation. This work contributes to advancing LLM capabilities for domain-specific applications, offering a robust solution for dynamic and complex e-commerce search environments.
Visibility as Survival: Generalizing NLP for Native Alaskan Language Identification
Authors: Ivory Yang; Chunhui Zhang; Yuxin Wang; Zhongyu Ouyang; Soroush Vosoughi
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: Indigenous languages remain largely invisible in commercial language identification (LID) systems, a stark reality exemplified by Google Translate’s LangID tool, which supports over 100 languages but excludes all 150 Indigenous languages of North America. This technological marginalization is particularly acute for Alaska’s 20 Native languages, all of which face endangerment despite their rich linguistic heritage. We present GenAlaskan, a framework demonstrating how both large language models and specialized classifiers can effectively identify these languages with minimal data. Working closely with Native Alaskan community members, we create Akutaq-2k, a carefully curated dataset of 2000 sentences spanning all 20 languages, named after the traditional Yup’ik dessert, symbolizing the blending of diverse elements. We design few-shot prompting on proprietary and open-source LLMs, achieving nearly perfect accuracy with just 40 examples per language. While initial zero-shot attempts show limited success, our systematic attention head pruning revealed critical architectural components for accurate language differentiation, providing insights into model decision-making for low-resource languages. Our results challenge the notion that effective Indigenous language identification requires massive resources or corporate infrastructure, demonstrating that targeted technological interventions can drive meaningful progress in preserving endangered languages in the digital age.
KodCode: A Diverse, Challenging, and Verifiable Synthetic Dataset for Coding
Authors: Zhangchen Xu; Yang Liu; Yueqin Yin; Mingyuan Zhou; Radha Poovendran
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: We introduce KodCode, a synthetic dataset that addresses the persistent challenge of acquiring high-quality, verifiable training data across diverse difficulties and domains for training Large Language Models for coding. Existing code-focused resources typically fail to ensure either the breadth of coverage (e.g., spanning simple coding tasks to advanced algorithmic problems) or verifiable correctness (e.g., unit tests). In contrast, KodCode comprises question–solution–test triplets that are systematically validated via a self-verification procedure. Our pipeline begins by synthesizing a broad range of coding questions, then generates solutions and test cases with additional attempts allocated to challenging problems. Finally, post-training data synthesis is done by rewriting questions into diverse formats and generating responses under a test-based reject sampling procedure from a reasoning model (DeepSeek R1). This pipeline yields a large-scale, robust and diverse coding dataset. It is suitable for supervised fine-tuning and the paired unit tests also provide great potential for RL tuning. Fine-tuning experiments on coding benchmarks (HumanEval(+), MBPP(+), BigCodeBench, and LiveCodeBench) demonstrate that KodCode-tuned models achieve state-of-the-art performance, surpassing models like Qwen2.5-Coder-32B-Instruct and DeepSeek-R1-Distill-Llama-70B.
Select, Read, and Write: A Multi-Agent Framework of Full-Text-based Related Work Generation
Authors: Xiaochuan Liu; Ruihua Song; Xiting Wang; Xu Chen
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: Automatic related work generation (RWG) can save people’s time and effort when writing a draft of related work section (RWS) for further revision. However, existing methods for RWG always suffer from shallow comprehension due to taking the limited portions of references papers as input and isolated explanation for each reference due to ineffective capturing the relationships among them. To address these issues, we focus on full-text-based RWG task and propose a novel multi-agent framework. Our framework consists of three agents: a selector that decides which section of the papers is going to read next, a reader that digests the selected section and updates a shared working memory, and a writer that generates RWS based on the final curated memory. To better capture the relationships among references, we also propose two graph-aware strategies for selector, enabling to optimize the reading order with constrains of the graph structure. Extensive experiments demonstrate that our framework consistently improves performance across three base models and various input configurations. The graph-aware selectors outperform alternative selectors, achieving state-of-the-art results. The code and data are available at https://github.com/1190200817/Full_Text_RWG.
Graph-Assisted Culturally Adaptable Idiomatic Translation for Indic languages
Authors: Pratik Rakesh Singh; Kritarth Prasad; Mohammadi Zaki; Pankaj Wasnik
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: Translating multi-word expressions (MWEs) and idioms requires a deep understanding of the cultural nuances of both the source and target languages. This challenge is further amplified by the one-to-many nature of idiomatic translations, where a single source idiom can have multiple target-language equivalents depending on cultural references and contextual variations. Traditional static knowledge graphs (KGs) and prompt-based approaches struggle to capture these complex relationships, often leading to suboptimal translations. To address this, we propose an IdiomCE, an adaptive graph neural network (GNN) based methodology that learns intricate mappings between idiomatic expressions, effectively generalizing to both seen and unseen nodes during training. Our proposed method enhances translation quality even in resource-constrained settings, facilitating improved idiomatic translation in smaller models. We evaluate our approach on multiple idiomatic translation datasets using reference-less metrics, demonstrating significant improvements in translating idioms from English to various Indian languages
Question Answering in Climate Adaptation for Agriculture: Model Development and Evaluation with Expert Feedback
Authors: Vincent Nguyen; Sarvnaz Karimi; Willow Hallgren; Mahesh Prakash
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: The generative capabilities of the large language models (LLMs) are deployed for domain-specific question answering systems. However, their ability to answer climate adaptation questions remains unclear. In particular, can they be used by agronomists and climate scientists to answer questions on the best climate adaptation strategies? Answering questions in this domain requires knowledge of climate data and its uncertainties, and the ability to link them to the broader climate literature while accommodating the unique constraints of users and experts. We investigate the generative and evaluative capabilities of several state-of-the-art LLMs, open-source and proprietary, on climate adaptation for agriculture questions posed by domain experts using evaluation criteria designed by the experts.We propose an iterative exploration framework that enables LLMs to dynamically aggregate information from heterogeneous sources, such as text from climate literature and structured tabular climate data from climate model projections and historical observations. Our experiments demonstrate that LLMs can aggregate heterogeneous data to (1) answer questions, but at a trade-off between presentation quality and epistemological accuracy; and, (2) evaluate answers, but are not as competent at identifying high-quality answers and erroneous information compared to domain experts.
AGRec: Adapting Autoregressive Decoders with Graph Reasoning for LLM-based Sequential Recommendation
Authors: Xinfeng Wang; Jin Cui; Fumiyo Fukumoto; Yoshimi Suzuki
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: Autoregressive decoders in large language models (LLMs) excel at capturing users’ sequential behaviors for generative recommendations. However, they inherently struggle to leverage graph-structured user-item interactions, which are widely recognized as beneficial. This paper presents AGRec, adapting LLMs’ decoders with graph reasoning for recommendation. We reveal that LLMs and graph neural networks (GNNs) manifest complementary strengths in distinct user domains. Building on this, we augment the decoding logits of LLMs with an auxiliary GNN model to optimize token generation. Moreover, we introduce a rankable finite state machine to tackle two challenges: (1) adjusting autoregressive generation with discriminative decoders that directly predict user-item similarity, and (2) token homogeneity, where LLMs often generate items with similar prefix tokens, narrowing the scope of beam search. This approach offers a novel perspective to enhance LLMs with graph knowledge. Our AGRec outperforms state-of-the-art models in sequential recommendations. Our code is available online.
Causal Denoising Prototypical Network for Few-Shot Multi-label Aspect Category Detection
Authors: Jin Cui; Xinfeng Wang; Yoshimi Suzuki; Fumiyo Fukumoto
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: The multi-label aspect category detection (MACD) task has attracted great attention in sentiment analysis. Many recent methods have formulated the MACD task by learning robust prototypes to represent categories with limited support samples. However, few of them address the noise categories in the support set that hinder their models from effective prototype generations. To this end, we propose a causal denoising prototypical network (CDPN) for few-shot MACD. We reveal the underlying relation between causal inference and contrastive learning, and present causal contrastive learning (CCL) using discrete and continuous noise as negative samples. We empirically found that CCL can (1) prevent models from overly predicting more categories and (2) mitigate semantic ambiguity issues among categories. Experimental results show that CDPN outperforms competitive baselines. Our code is available online.

Abstract: With the rapid advancement of Large Language Models (LLMs), there is an increasing need for challenging benchmarks to evaluate their capabilities in handling complex tabular data. However, existing benchmarks are either based on outdated data setups or focus solely on simple, flat table structures. In this paper, we introduce **RealHiTBench**, a comprehensive benchmark designed to evaluate the performance of both LLMs and Multimodal LLMs (MLLMs) across a variety of input formats for complex tabular data, including LaTeX, HTML, and PNG. RealHiTBench also includes a diverse collection of tables with intricate structures, spanning a wide range of task types. Our experimental results, using **25** state-of-the-art LLMs, demonstrate that RealHiTBench is indeed a challenging benchmark. Moreover, we also develop TreeThinker, a tree-based agent that organizes hierarchical headers into a tree structure for enhanced tabular reasoning, validating the importance of improving LLMs’ perception of table hierarchies. We hope that our work will inspire further research on tabular data reasoning and the development of more robust models. The code and data are available at https://github.com/cspzyy/RealHiTBench.
A Query-Response Framework for Whole-Page Complex-Layout Document Image Translation with Relevant Regional Concentration
Authors: Zhiyang Zhang; Yaping Zhang; Yupu Liang; Zhiyuan Chen; Lu Xiang; Yang Zhao; Yu Zhou; Chengqing Zong
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: Document Image Translation (DIT), which aims at translating documents in images from source language to the target, plays an important role in Document Intelligence. It requires a comprehensive understanding of document multi-modalities and a focused concentration on relevant textual regions during translation. However, most existing methods usually rely on the vanilla encoder-decoder paradigm, severely losing concentration on key regions that are especially crucial for complex-layout document translation. To tackle this issue, in this paper, we propose a new Query-Response DIT framework (QRDIT). QRDIT reformulates the DIT task into a parallel response/translation process of the multiple queries (i.e., relevant source texts), explicitly centralizing its focus toward the most relevant textual regions to ensure translation accuracy. A novel dynamic aggregation mechanism is also designed to enhance the text semantics in query features toward translation. Extensive experiments in four translation directions on three benchmarks demonstrate its state-of-the-art performance, showing significant translation quality improvements toward whole-page complex-layout document images.
DependEval: Benchmarking LLMs for Repository Dependency Understanding
Authors: Junjia Du; Yadi Liu; Hongcheng Guo; Jiawei Wang; Haojian Huang; Yunyi Ni; Zhoujun Li
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: While large language models (LLMs) have shown considerable promise in code generation, real-world software development demands advanced repository-level reasoning. This includes understanding dependencies, project structures, and managing multi-file changes. However, the ability of LLMs to effectively comprehend and handle complex code repositories has yet to be fully explored. To address these challenges, we introduce a hierarchical benchmark designed to evaluate repository dependency understanding(DependEval) for LLMs. The benchmark is based on 2683 repositories collected from real-world websites. It evaluates models on three core tasks: Dependency Recognition, Repository Construction, and Multi-file Editing, across 8 programming languages from actual code repositories. Our evaluation of over 25 LLMs reveals substantial performance gaps and provides valuable insights into repository-level code understanding.
A General Knowledge Injection Framework for ICD Coding
Authors: Xu Zhang; Kun Zhang; Wenxin Ma; Rongsheng Wang; Chenxu Wu; Yingtai Li; S Kevin Zhou
Venue: ACL 2025 (Findings of the Association for Computational Linguistics: ACL 2025)

Abstract: ICD Coding aims to assign a wide range of medical codes to a medical text document, which is a popular and challenging task in the healthcare domain. To alleviate the problems of long-tail distribution and the lack of annotations of code-specific evidence, many previous works have proposed incorporating code knowledge to improve coding performance. However, existing methods often focus on a single type of knowledge and design specialized modules that are complex and incompatible with each other, thereby limiting their scalability and effectiveness. To address this issue, we propose GKI-ICD, a novel, general knowledge injection framework that integrates three key types of knowledge, namely ICD Description, ICD Synonym, and ICD Hierarchy, without specialized design of additional modules. The comprehensive utilization of the above knowledge, which exhibits both differences and complementarity, can effectively enhance the ICD coding performance. Extensive experiments on existing popular ICD coding benchmarks demonstrate the effectiveness of GKI-ICD, which achieves the state-of-the-art performance on most evaluation metrics. Code is available at https://github.com/xuzhang0112/GKI-ICD.
