A Design of Mixed-Initiative Learning System : European Geography Learning System

Recently, several researches on CAI (Computer-Assisted Instruction) system utilizing the information network have been developed. They intend the system to have mixed-initiative, that is, both the system and the student can initiate conversation by asking questions each other. As one of such approaches, we design the ”European geography learning system” based on the concept of Quillian's ”semantic net”. This system is programmed by the symbol manupulating language LISP, and both the student's input and the system's output are simple English sentences.
