Abstract:

Information extraction is crucial for building and updating the knowledge base of expert systems. Large language models face challenges with prompt sensitivity and model hallucinations during information extraction. This study introduces the TIME (Tourism, Individuals, Moments, Events) model, which organizes figure-related information into four main dimensions: attributes, relationships, events, and their linkage to tourism resources. Then present a unified information extraction framework for figures, termed TIME-UIE. This framework integrates a unified task definition, a format output constraint, carefully selected demonstrations, and knowledge injection to verify consistency across different inference chains. Experimental results show that TIME-UIE outperforms baseline models in deciphering complex relationships between historical figures by 26.2% and in extracting event triplets by 11.1%. The study also proposes a loose matching metric for model performance evaluation, which holds significant implications for the practical application of the research methods.
