Context Modeling for Developing a Database System of Authentic Case in Training Cyber Police

As the number of computer crime increase fast and the crime technologies update quickly, cyber police need ongoing training. In order to supply better training case resources, we developed a database system of authentic case. The previous case representations which are content-based are not suitable for the crime case. In this paper, we propose a new context model to represent authentic case context. The model includes entity, character, event and episode. The model has been used in the database system, and the system has been used in training cyber police. The practice result shows that the context model is effective and reasonable.
