A Dual-Mind Framework for Strategic and Expressive Negotiation Agent (2025.acl-long)
Copied to clipboard
| Challenge: | Existing approaches to negotiation dialogue focus on only one aspect, ignoring the synergistic effect of their combined synergies. |
| Approach: | They propose a dual-mind negotiation agent framework that integrates an intuitive and a deliberative module for slow, expression optimization. |
| Outcome: | The proposed framework achieves state-of-the-art on negotiation datasets showing that it improves negotiation ability. |
Enhancing Multimodal Large Language Models for Ancient Chinese Character Evolution Analysis via Glyph-Driven Fine-Tuning (2026.acl-long)
Copied to clipboard
| Challenge: | Existing studies have explored the evolutionary analysis of ancient scripts, with particular attention to the transformation of character forms from oracle bone inscriptions to regular script. |
| Approach: | They propose a benchmark framework that leverages MLLMs to analyze the evolution of ancient Chinese scripts. |
| Outcome: | The proposed framework improves performance on core tasks and character recognition and evolutionary reasoning tasks while limiting performance on other tasks. |
A Simple Contrastive Learning Framework for Interactive Argument Pair Identification via Argument-Context Extraction (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing work on argument mining uses context-based methods to identify whether two arguments are interactively related. |
| Approach: | They propose a contrastive learning framework to extract valuable information from the context. |
| Outcome: | The proposed framework achieves state-of-the-art performance on the benchmark dataset and visually displays more compact representations. |
ACSE: An Ancient Character Semantic-Aware Embedding for Large Language Models (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing studies on pre-Qin documents are insufficient to understand ancient characters . ancient characters have a low level of digitization and training corpora are extremely scarce . |
| Approach: | They propose a semantic-aware embedding for ancient Chinese characters that integrates glyphs and lexicality into modern Chinese semantic space. |
| Outcome: | The proposed model integrates glyph and lexicality of ancient characters and maps them to the modern Chinese semantic space. |
Self-supervised Preference Optimization: Enhance Your Language Model with Preference Degree Awareness (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Recent studies have focused on replacing the reward model in Reinforcement Learning with Human Feedback (RLHF) methods for Large Language Models (LLMs). |
| Approach: | They propose a self-supervised preference optimization framework that replaces the reward model with a preference loss and alignment loss to improve LLMs' ability to understand human preferences. |
| Outcome: | The proposed framework can be integrated with existing preference optimization methods and significantly boost their performance. |
