The aim is to develop a knowledge graph-based model for effective data management and personalized information services in university libraries.
Constructed a hierarchical model with five core layers: data source, data processing, knowledge construction, service application, and user interaction.
Integrated multi-source heterogeneous data resources into a unified knowledge framework.
Utilized dynamic fusion methods combining large language models and graph embedding for data integration.
Implemented knowledge graph semantic associations for personalized information recommendations.
User experience score improved from 3.03 to 4.40, a 45.2% increase.
Search result accuracy increased by 41.1%.
Service quality and learning effectiveness enhanced by 32.5% and 41.7%, respectively.
All 16 technical indexes met or exceeded established standards.
