Understanding sentiment changes in tourist flow is critical in designing exciting experiences for tourists and promoting sustainable tourism development This paper proposes a novel analytical framework to investigate the tourist sentiment changes between different attractions based on geotagged social media data Our framework mainly focuses on visualizing the detailed sentiment changes of tourists and exploring the valuable spatiotemporal pattern of the sentiment changes in tourist flow The tourists were first identified from social media users Then, we accurately evaluated the tourist sentiment by constructing a Chinese sentiment dictionary, grammatical rule, and sentiment score Based on the location information of social media data, we built and visualized the tourist flow network Last, to further reveal the impact of attractions on the sentiment of tourist flow, the positive and negative sentiment profiles were generated by mining social media texts We took Beijing, a famous tourist destination in China, as a case study Our results revealed the following: (1) the temporal trend of tourist sentiment has seasonal characteristics and is significantly influenced by government control policies against COVID-19;(2) due to the impact of the attraction's historical background, some tourist flows with highly decreased sentiment strength are linked to attractions;(3) on the long journey to the attraction, the sentiment strength of tourists decreases;and (4) bad traffic conditions can significantly decrease tourist sentiment This study highlights the methodological implications of visualizing sentiment changes during collective tourist movement and provides comprehensive insight into the spatiotemporal pattern of tourist sentiment [ABSTRACT FROM AUTHOR] Copyright of ISPRS International Journal of Geo-Information is the property of MDPI Publishing and its content may not be copied or emailed to multiple sites or posted to a listserv without the copyright holder's express written permission However, users may print, download, or email articles for individual use This abstract may be abridged No warranty is given about the accuracy of the copy Users should refer to the original published version of the material for the full abstract (Copyright applies to all Abstracts )
