Research on Classification Method of Building Function Oriented to Urban Building Stock Management

Abstract

With the development of human society, the urban population and the urban building stock have been continuously increasing. Environmental issues such as greenhouse gases emissions, air pollution, and construction waste have gradually emerged. Due to the lack of an urban functional area database, it is very time-consuming to manually identify building functional areas. As a result, most of the current research on urban building functions are estimated at a large regional scale or only detailed calculations of individual buildings. The building functions classification method needs to be further improved. Based on the traditional methods, this paper proposes a building function classification method with higher recognition accuracy and is less time-consuming. The method is then applied to a certain area of Chaoyang District, Beijing, for validation and verification. The results show that the urban building function classification method in this paper has a recognition rate of 96.18%, an overall classification accuracy of 94.37%, and a kappa coefficient of 0.9089. The classification results are in good agreement with the virtual interpretation. In addition, automatic classification of building functions is implemented using ArcPy in ArcGIS, which significantly improves the classification efficiency.

Semantic enrichment of building functions through geospatial data integration and ontological inference

“…Deng et al (2022) propose a hierarchical data-mining model to identify building functions using freely accessible auxiliary data. Xiao et al (2022) improve the existing building function classification method with data scraping to obtain POI data, building footprint data, and real estate information. Despite a considerable body of literature focused on inferring building functions, there is a dearth of research on how to effectively integrate and enrich multiple data sources using semantic web technologies for classification of buildings by their functions.…”
