Abstract:Based on a summary of literature review and 4,062 valid sample data collected, through model construction, variable definition, data acquisition and analysis, combined with semantic analysis of open questions, the audience satisfaction of China Science and Technology Museum is studied. The audience satisfaction model of the science and technology museum is mainly built of 4 dimensions: user expectations, service perception, user trust and user complaint; through exploratory factor analysis of the observed variables, three common factors of service content, exhibit status and visit effect are extracted. According to the variance contribution rate, each factor is given a different weight. Through data analysis of effective samples, as well as text analysis and semantic understanding of open questions, practical suggestions for the China Science and Technology Museum are provided to improve audience satisfaction.
