【Purpose/significance】 By constructing a knowledge graph of the former residences of celebrities in Shanghai, we can

strengthen the knowledge organization problem of unstructured data of the former residences of celebrities in Shanghai, provide ideas and reference methods for subsequent research on academic resources of historical celebrity residences, and also facilitate tourists' choice of celebrity residences tours.【Method/process】 In this paper, based on the needs of users of the former residences of celebrities in Shanghai and related industry standards in the field of tourism, we firstly design the knowledge graph framework of the former resi⁃dences of celebrities in Shanghai using a top-down approach, and then fill in the entities, relationships and attributes of the graph based on this framework through sequence annotation and machine learning methods to provide data support for the construction of the knowledge graph of the former residences of celebrities in Shanghai, and finally apply the Neo4j graph database to the knowledge graph of the former residences of celebrities in Shanghai. Finally, we use Neo4j graph database to visualize and store the knowledge graphs of Shanghai's famous houses.【Result/conclusion】 The knowledge graph of Shanghai's famous houses is constructed to realize the visual storage and semantic retrieval of resources, which can provide data browsing and knowledge display, data query and knowl⁃edge retrieval, knowledge association and information recommendation, and lay the foundation for the subsequent application research of intelligent question and answer and intelligent information recommendation.【Innovation/limitation】 This study constructs a knowl⁃edge mapping framework of the former residences of celebrities in Shanghai by combining user requirements and data structure charac⁃teristics of the former residences of celebrities in Shanghai, which provides ideas for subsequent research related to knowledge organi⁃zation of celebrity residences. The selection of data in this paper is limited to the well-known celebrity residences in Shanghai, and the relevant research data should be further expanded to better study the applicability of the article method.
