CONSTRUCTION OF 3D DESIGN KNOWLEDGE SYSTEM BASED ON MICROBLOG MINING
ABSTRACT
With the advent of the era of big data, this article aims to briefly describe the related issues of 3D design knowledge in Weibo. Through text analysis of the articles on 3D knowledge in Weibo, the domestic 3D design knowledge system is constructed. Use Python code to mine the knowledge about 3D design in Weibo, then analyze the content, complete the correction and selection of the excavated data, form a keyword list, and according to the intersection and complexity of 3D design knowledge Innovative, clarify the knowledge domain of the 3D design knowledge system, and summarize the structure diagram of the 3D design knowledge system, thereby further forming a knowledge system. Through the construction of the 3D design knowledge system, it can be seen that the public is very interested in 3D design, and the development of 3D design in China is very rapid. Understanding 3D design knowledge correctly and clearly can enable everyone to better grasp and use it. Therefore, constructing a threedimensional design knowledge system can realize a full range of perception and application for teachers and researchers. This article uses the meaning of the 3D design knowledge system and the relevant components required for the relevant construction to realize a forming idea for the 3D design knowledge system. It has practical significance for the improvement of my countrys 3D design, and at the same time, it can provide materials for subsequent related research. At the same time, there are more and more fields to study and apply 3D design knowledge. This article is based on the number of related blog posts and related entry data in Weibo, according to the relevant theory of the knowledge system, combined with the text analysis method, the analyzed knowledge unit and its summarized knowledge body. Established a threedimensional design knowledge system.
