In order to analyse the factors and dimensions that customers pay attention to smart hotels, this experiment selects the user reviews of five smart hotels on Ctrip as the research samples, and carries out network text big data collection, text pre-processing and topic mining through the relevant algorithms of Python programming language. The results show that customers’ accommodation experience of smart hotel mainly includes five aspects: breakfast and transportation, staff service level, intelligent service, room environment, and room hardware facilities. Among them, the customer’s attention to the intelligent services of smart hotels and the intelligentization of hardware facilities in guest rooms reflect the difference in customer experience between smart hotels and traditional hotels, which provides a certain reference for the optimization of hotel service levels.
