Overview of ICH Information Extraction
The study addresses the challenges of accurately extracting and understanding information from visual business cards of Intangible Cultural Heritage (ICH) inheritors. These challenges include heterogeneous data sources, diverse layout styles, specialized terminology, and the need for contextual understanding. The proposed **Graph-Retrieval framework** integrates graph-based methods with Retrieval-Augmented Generation (RAG) to enhance information recognition and question answering in the ICH domain.
Key contributions include the construction of a **Chinese ICH inheritor visual card dataset** (5237 cards, 10 information types), a **graph feature enhancement method** for robust extraction, and a **Loop-RAG strategy** for accurate and semantically rich content generation, mitigating hallucination risks inherent in large language models (LLMs).

Case Study: Intelligent Q&A for ICH Inheritors
The Loop-RAG strategy significantly improves question answering accuracy for ICH-related queries, especially for complex and domain-specific information. By dynamically integrating external knowledge and refining retrieval through inner-outer loops, the system effectively mitigates LLM hallucinations and enhances factual consistency.
For example, the **Loop-RAG-GPT4** model achieved an F1 score of **0.941** in the Q&A task, demonstrating a **7.05% improvement** over the original GPT-4 model. This ensures more accurate and contextually rich responses, crucial for preserving and disseminating intangible cultural heritage.
The system excels in few-shot learning, where it maintains high accuracy even with limited examples. In 3-shot conditions, Loop-RAG-GPT4 reached an F1 of **0.954**, significantly outperforming other models.
