Cyber-Individual (Cyber-I) is a cyber-counterpart of a real individual (Real-I) in the physical world. It involves a comprehensive description of Real-I and facilitates the digital existence of Real-I in the cyber world. As a copy or digital clone of Real-I, Cyber-I has a life cycle comprising birth, growth, and death processes. One of the basic characteristics of the growth of Cyber-I is to continuously process successive and life-long data for approximation of its Real-I. That is, the model of a Cyber-I should be built incrementally and refined successively. Therefore, this study focuses on an incremental mechanism for a growable Cyber-I. The web browsing logs of a user-as a type of personal data-are collected daily, weekly, and monthly for incremental modeling of the online activity patterns of the user. With incremental processing of the collected data, the model of Cyber-I can be enhanced with detailed and precise feature descriptions of the online activities of the user. A prototype system is implemented to demonstrate the proposed incremental modeling method for Cyber-I growth along with successive data coming and processing. The actual browsing data are used to test and evaluate the developed system.
