In this paper, a website for teaching artificial intelligence (AI) is developed based on the system of AI concepts. The concept system is used to link the course content with more AI resources such as papers, books, technique reports, multimedia materials, virtual experiments, and etc. Consequently, a student can easily and orderly browses through AI knowledge which is beyond the classroom. It is beneficial to self-learning and self-improvement of students. Furthermore, we attach great importance to the communication between teachers and students.
