Toward sustainable and differentiated protection of cultural heritage illustrated by a multisensory analysis of Suzhou and Kyoto using deep learning
摘要
Residents’ perception is essential to cultural heritage (CH) and place identity, making its integration into sustainable conservation important. This study analyzes online reviews from Suzhou and Kyoto using deep learning to extract multisensory descriptions and physical elements. Sentiment analysis shows that overall perceptions are predominantly positive. In Suzhou, visual perception dominates, with a dynamic spatial experience, while other sensory inputs are limited. Kyoto offers richer multisensory engagement and greater openness, though with less spatial variation. Visitors differ significantly in their perceptions of sensory experiences and physical settings. Multiple linear regression indicates that multisensory engagement enhances overall perception, shaped by the environment. However, cost and accessibility are key negative factors influencing impressions. This study highlights the importance of incorporating multisensory public perceptions into CH conservation and supports differentiated, site-specific strategies. The findings contribute to a nuanced understanding of sustainable heritage space optimization based on multisensory experiences and contextual factors.
