Can Multi-agent Help Disambiguation in Multi-domain Translation? (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing multi-agent systems have shown strong potential for machine translation (MT) but their performance in multidomain translation remains unsatisfactory due to cross-domain word ambiguity . |
| Approach: | They propose a multi-agent collaborative disambiguation framework for MDT that leverages the collaborative capabilities of LLMs for disambiguations. |
| Outcome: | The proposed framework improves translation performance across multiple domains and improves disambiguation accuracy. |

| Challenge: | Recent advances in Automated Theorem Proving have shown the effectiveness of leveraging a (large) language model that generates tactics (i.e. proof steps) to search through proof states. |
| Approach: | They propose to use a large language model that generates tactics to search through proof states. |
| Outcome: | The proposed model solves more unseen theorems with lower trial searches than the current model, which only learns from failed attempts. |
DMDTEval: An Evaluation and Analysis of LLMs on Disambiguation in Multi-domain Translation (2025.emnlp-main)

| Challenge: | Currently, Large Language Models (LLMs) have achieved remarkable results in machine translation, but their performance in multidomain translation (MDT) is less satisfactory. |
| Approach: | They propose to evaluate the disambiguation ability of Large Language Models in multi-domain translation . they construct a translation test set with multi- domain ambiguous word annotation . |
| Outcome: | The proposed framework evaluates LLMs on disambiguation in multi-domain translation (DMDTEval) the results show that LLM's perform poorly in multidomain translation, highlighting ambiguity in translation. |

| Challenge: | Recent Large Multimodal Models (LMMs) have shown promising potential for performing end-to-end KIE directly from document images. |
| Approach: | They propose a benchmark to evaluate the performance of Large Multimodal Models (LMMs) using a constrained-category KIE track and an open-categorical KIE Track. |
| Outcome: | Experiments on 15 state-of-the-art LMMs show performance degradation under diverse schema definitions, long-tail key fields, and complex layouts, along with pronounced performance disparities across different document types and scenarios. |
SoT: Structured-of-Thought Prompting Guides Multilingual Reasoning in Large Language Models (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Large Language Models struggle with multilingual reasoning tasks due to resource constraints . a training-free method improves performance on multilingual thinking tasks . |
| Approach: | They propose a training-free method that transforms language-specific semantic information into language-agnostic structured representations. |
| Outcome: | The proposed method outperforms strong baselines on multilingual reasoning tasks. |
ICL: Iterative Continual Learning for Multi-domain Neural Machine Translation (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Existing studies have focused on learning domain knowledge from multiple domains, but task-specific parameters hinder mutual transfer of knowledge between new domains. |
| Approach: | They propose an iterative Continual learning framework for multi-domain neural machine translation that leverages previously acquired domain knowledge. |
| Outcome: | The proposed model outperforms baseline models on UM-Corpus and OPUS datasets. |
SEAL: Structure and Element Aware Learning Improves Long Structured Document Retrieval (2025.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for document retrieval use contrastive learning on datasets lacking explicit structural information. |
| Approach: | They propose a contrastive learning framework that preserves semantic hierarchies and masked element alignment for fine-grained semantic discrimination. |
| Outcome: | The proposed framework preserves semantic hierarchies and masked element alignment for fine-grained semantic discrimination. |
