VietMed-MCQ: A Consistency-Filtered Data Synthesis Framework for Vietnamese Traditional Medicine Evaluation

VietMed-MCQ:面向越南传统医学评估的一致性过滤数据合成框架

Huynh Trung Kiet, Dao Sy Duy Minh, Nguyen Dinh Ha Duong, Le Hoang Minh Huy, Long Nguyen, Dien Dinh

专题命中 RAG评测 :RAG(abstract,abstract_cn);retrieval-augmented generation(abstract);分类 cs.CL

AI总结 提出基于检索增强生成和一致性过滤的VietMed-MCQ数据集,含3190道多选题,经专家验证准确率94.2%,基准测试显示通用模型优于越南语模型。

Comments The authors have withdrawn this article because the current version is still undergoing substantial revision. Several components of the data synthesis framework, consistency-filtering procedure, evaluation protocol, and experimental analysis are being refined and expanded. As a result, the current manuscript should not be considered a complete or final representation of the work
