Framework and Implementation of the Virtual Item Bank System

Bagua, I Ching was applied to tell the fortune of people in ancient Chinese. In the modern era, we apply tests to infer the intelligence, future development direction and potential of people. However, it is not easy to design tests, and the security issue has also become a difficulty for test designers. This study has employed Item Response Theory (IRT) and Content-based image retrieval (CBIR) to establish an item bank. There are no actual items in the item bank. What replaces it is a Virtual Item Bank system (VIBs). In the VIBs, there are only the basic objects and processes in the VIBs. The items that are created by adopting the systems are directly created through the objects and processes. The system completely resolves the security issue of the item bank, and a variety of exercise systems created by adopting the system also have considerable help in enhancing students’ abilities.
