Abstract
It is essential to give full consideration to the potential barriers facing urban parks from their better functions and meeting residents' needs in terms of collective perception and satisfaction. This paper presents the methods of using social media (Dianping) data to investigate the potential factors affecting people's satisfaction with urban parks in Shenzhen, China. Textual analysis and sentiment analysis make it feasible to identify the factors influencing people's experience in parks. By measuring emotions towards these factors, a multiple linear regression model helps to explore the relationships between the factors and people's satisfaction, and among them, determines the key ones. The results present the nine key factors of urban parks that affect the users' satisfaction, in addition to the common factors by previous studies including park size, vegetation, recreation facility, landscape visual effect, maintenance of facilities and plants, and environment cleanliness. A series of contextual factors also significantly influence people's satisfaction, such as sign system, mosquito and air quality. Among these, sign system has the strongest influence. The results increase the understanding of the human-urban park relationship and identify the characteristics of urban parks that facilitate the degree of satisfaction promotion. Our findings may provide the managerial guidelines for planners and decision-makers to optimize people's imperative qualities of urban life.
