【Abstract】 DGTS (Descriptive Geometry Teaching System) was a AI-based descriptive geometry teaching system. In this paper, the structure, function and the implementation of DGTS was described. A combinative representation scheme of combining semantic network and production rule was used for the teaching-constant of descriptive geomentry. The student model and teacher model was included in DGTS . The student model could be renewed in time, and the teacher model might lead the student study. The natural language interface was adopted , so that the interactive mobility was enhanced greatly.更多还原
