Construction and Implementation of Tibetan Cultural Relics Question and Answer System Based on Knowledge Graph

Abstract

Tibet is a region with a long history and culture, with a large number of precious cultural relics resources. In the digital age, building a question-and-answer system based on the Knowledge map of Tibetan cultural relics can better protect and pass on Tibetan cultural heritage. Firstly, the Tibetan cultural relics data were obtained by crawler technology and stored in neo4j database to complete the knowledge graph construction. Secondly, in order to make the system understand the semantic information of the user's question, the bert_bilstm_crf model is used to recognize the entity information of the question, and the bert_textcnn model is used to recognize the intention of the question, and finally the answer result is returned by constructing the cypher query graph.
