With the growing popularity of the internet, customers can easily share their experiences and information in online reviews. Consumers recognize online reviews as a useful source of information prior to consumption, and many online reviews influence consumer purchasing decisions. Understanding the customer experience in online reviews is thus necessary to maintain customer satisfaction and repurchase intention for the sustainable development of the hotel business. This study assessed the fundamental selection attributes of customers from online reviews reflecting the hotel customer experience, and investigated their association with customer satisfaction. A total of 8229 reviews were collected from Google travel websites from December 2019 to July 2021. Text mining and semantic network analysis were adopted for big data analysis. Factor and regression analyses were then used for quantitative analysis. Based on linear regression analysis, the Service and Dining factors significantly affected customer satisfaction. Service is a critical selection attribute for customers, and the provision of more particular services is necessary, especially after COVID-19. These results indicate that understanding online reviews can provide theoretical and practical implications for developing sustainable strategies for the hotel industry.

The purpose of this study was to identify the problems of online education perceived by learners in a time when non-face-to-face online lectures are conducted due to the spread of COVID-19, and suggest measures to improve educational outcomes. Therefore, the structural influence of cooking practice on the quality of online lessons, learning immersion, learning satisfaction, and the achievement felt by learners was verified. The sample of the study was a college student majoring in cooking, and a total of 509 responses were used for analysis. The results of the study are as follows: First, it was analyzed that there was a significant influence on learning immersion in the order of content, interaction, and educational environment among the quality of online classes. Second, among the quality of online classes, class content and educational environment showed positive (+) influence on learning satisfaction. Third, learning immersion and learning satisfaction showed a positive influence on academic achievement. Fourth, in the direct effect of online class quality on academic achievement, it was analyzed that only class content had a positive (+) effect. Based on the results of this study, the provision of learning materials with detailed explanations was suggested in the online cooking practice class rather than providing a simple cooking video. In addition, it was suggested that as a way to improve academic achievement of online education, it is necessary to provide content that allows learners to immerse themselves in class, as well as class content and educational environment, and consider learning satisfaction.
