[Abstract]:In order to solve the problem that it is difficult for architects to retrieve architectural images from the Internet quickly, a semantic acquisition method of architectural images based on Web tagging technology is proposed. Firstly, the concept and types of architectural image and architectural image semantics are defined from the architectural point of view. Secondly, the overall framework and operation flow of this method are given. Finally, a case study of famous construction website is presented. The feasibility and effectiveness of the method are verified. The operation flow is subdivided into three steps to establish the architectural semantic dictionary by manual addition and online learning, and to collect the image name, image annotation and the text around the image from the web page of the building image by using the data acquisition software. The title of the web page, the body of the web page, the image hyperlink page title, 6 items of image related text, and the architectural image semantics are extracted from the text according to the rules of image semantic extraction. After establishing an association with the image file, it is stored in the building image database. The results of case study show that the method is feasible and has strong maneuverability. It can automatically and batch download building images from the Internet, and collect image names, image categories, image themes, project names, etc. More than 30 features, such as project types, effectively overcome the problem of low efficiency of architectural image query, and then enhance the ability of architects to create images on the Internet.
