The Characteristics of Digital Twin in Cyberspace: A Knowledge Perspective

The essence of digital twin is to realize orderly flow and evolution innovation of knowledge as a computable knowledge extractor as well as carrier. In view of the urgency and scarcity of the current research on digital twin from the perspective of knowledge, this paper starts with the main factors that promote the origin, development and formation of the concept of digital twin from a temporal point of view, analyses the connotation of knowledge in cyberspace, and make further efforts to expound several significant characteristics of digital twin in cyberspace. The purpose of this study is to open up a new field of vision for the theoretical research of digital twin, and show a clear direction for future work to deal with a series of important issues of digital twin such as model integration and construction, model interaction and collaboration, individual and group self-evolution, and open extensible architecture construction.
