Cultural relics are the valuable wealth left behind by ancestors in the process of historical development, and they are an important carrier connecting the past and the present. The development of digital technology provides more development paths for the display of cultural relics. In this paper, we use BERT-BiLSTM-CRF modeling technology to extract the cultural relic entities, construct the knowledge graph ontology and RDF triad, and propose the cultural relics knowledge graph expression model. Combined with the reasoning engine based on the TBCRM model, the determination of cultural relic entities and relationships in the knowledge graph is realized. By adopting the cultural relics knowledge mapping expression model to integrate cultural relics resources and digitally display them, a digital cultural relics museum system construction method is proposed with the back-end data service layer, intermediate application layer and front-end Web browsing layer as the main framework. The application of this method assists in the establishment of a digital display system for the cultural relics museum in Province B. The overall function obtains an average user rating between 70-90, showing a high practical effect.
