A Query-Response Framework for Whole-Page Complex-Layout Document Image Translation with Relevant Regional Concentration

ACL 2025finding

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…

From Chaotic OCR Words to Coherent Document: A Fine-to-Coarse Zoom-Out Network for Complex-Layout Document Image Translation

COLING 2025main

Document Image Translation (DIT) aims to translate documents in images from one language to another. It requires visual layouts and textual contents understanding, as well as document coherence capturing. However, current methods often rely on the quality of OCR output, which, particularly in comple…

From Generic Empathy to Personalized Emotional Support: A Self-Evolution Framework for User Preference Alignment

EMNLP 2025

Effective emotional support hinges on understanding users’ emotions and needs to provide meaningful comfort during multi-turn interactions. Large Language Models (LLMs) show great potential for expressing empathy; however, they often deliver generic responses that fail to address users’ specific nee

Improving MLLM’s Document Image Machine Translation via Synchronously Self-reviewing Its OCR Proficiency

ACL 2025finding

Multimodal Large Language Models (MLLMs) have shown strong performance in document image tasks, especially Optical Character Recognition (OCR). However, they struggle with Document Image Machine Translation (DIMT), which requires handling both cross-modal and cross-lingual challenges. Previous effor…

Single-to-mix Modality Alignment with Multimodal Large Language Model for Document Image Machine Translation

ACL 2025long

Document Image Machine Translation (DIMT) aims to translate text within document images, facing generalization challenges due to limited training data and the complex interplay between visual and textual information. To address these challenges, we introduce M4Doc, a novel single-to-mix Modality ali…

SweetieChat: A Strategy-Enhanced Role-playing Framework for Diverse Scenarios Handling Emotional Support Agent

COLING 2025main

Large Language Models (LLMs) have demonstrated promising potential in providing empathetic support during interactions. However, their responses often become verbose or overly formulaic, failing to adequately address the diverse emotional support needs of real-world scenarios. To tackle this challen…

Document Image Machine Translation with Dynamic Multi-pre-trained Models Assembling

NAACL 2024long

Text image machine translation (TIMT) is a task that translates source texts embedded in the image to target translations. The existing TIMT task mainly focuses on text-line-level images. In this paper, we extend the current TIMT task and propose a novel task, **D**ocument **I**mage **M**achine **T*…

LayoutDIT: Layout-Aware End-to-End Document Image Translation with Multi-Step Conductive Decoder

EMNLP 2023long findings

Document image translation (DIT) aims to translate text embedded in images from one language to another. It is a challenging task that needs to understand visual layout with text semantics simultaneously. However, existing methods struggle to capture the crucial visual layout in real-world complex d…

Other Roles Matter! Enhancing Role-Oriented Dialogue Summarization via Role Interactions

ACL 2022long

Role-oriented dialogue summarization is to generate summaries for different roles in the dialogue, e.g., merchants and consumers. Existing methods handle this task by summarizing each role’s content separately and thus are prone to ignore the information from other roles. However, we believe that ot…

CSDS: A Fine-Grained Chinese Dataset for Customer Service Dialogue Summarization

EMNLP 2021main

Dialogue summarization has drawn much attention recently. Especially in the customer service domain, agents could use dialogue summaries to help boost their works by quickly knowing customer’s issues and service progress. These applications require summaries to contain the perspective of a single sp…

Knowledge Graph Enhanced Neural Machine Translation via Multi-task Learning on Sub-entity Granularity

COLING 2020main

Previous studies combining knowledge graph (KG) with neural machine translation (NMT) have two problems: i) Knowledge under-utilization: they only focus on the entities that appear in both KG and training sentence pairs, making much knowledge in KG unable to be fully utilized. ii) Granularity mismat…
