Research in this area is limited due to the lack of large-scale datasets. Moreover, timely studies are indeed necessary under pandemic conditions. This study employs quantitative methods to analyze the temporal and spatial changes in social interaction in 160 urban parks before, during, and after the COVID-19 pandemic, and assesses their correlation with the built environment. Social media data from the Dianping platform were collected for this purpose. A two-step analytical approach was employed: first, machine learning-based keyword analysis identified review data related to social interaction, leading to the construction of two indicators: social interaction intensity and social interaction recovery rate. Second, we applied regression models to explore the correlation between the two indicators in urban parks and 18 characteristics of the built environment. The built environment characteristics associated with social interaction intensity varied across different periods, with seven factors, including natural landscapes, perceptual experience, building density, and road intersections, showing significant correlations with the recovery of social interaction capabilities in the post-pandemic era. Based on these findings, it is recommended that urban planners consider integrating more flexible design element, such as adding greenery and enriching the audio-visual experience for visitors. Furthermore, enhancing the quality and accessibility of park amenities can foster social interaction, thereby contributing to public health resilience in future crises. This research recommends that urban park design should not only support communities\u2019 immediate needs but also prepare for unforeseen challenges.<\/jats:p>","DOI":"10.3390\/ijgi14020087","type":"journal-article","created":{"date-parts":[[2025,2,17]],"date-time":"2025-02-17T12:36:57Z","timestamp":1739795817000},"page":"87","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Understanding Urban Park-Based Social Interaction in Shanghai During the COVID-19 Pandemic: Insights from Large-Scale Social Media Analysis"],"prefix":"10.3390","volume":"14","author":[{"given":"Haotian","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Land Surveying and Geo-Informatics, The Hong Kong Polytechnic University, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1702-8600","authenticated-orcid":false,"given":"Tianyu","family":"Su","sequence":"additional","affiliation":[{"name":"Graduate School of Design, Harvard University, Cambridge, MA 02138, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wanting","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Architecture, Southeast University, Nanjing 211189, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1016\/j.progress.2009.03.001","article-title":"Hot, congested, crowded and diverse: Emerging research agendas in planning","volume":"71","author":"Blanco","year":"2009","journal-title":"Prog.
