The Design And Implementation Of A Heuristic Natural Language Interface In Icai System

The natural language interface is an important component in Intelligent Computer Assisted Instruction (ICAI) system. This paper describes in detail the designing method and implementation techniques of a heuristic natural language interface In an ICAI system which is oriented to the chemistry course for students in middle school (the system is named CCICAI). The designing method and implementation techniques integrate properly the natural language and speech processing techniques and also the characteristics of heuristic teaching. The natural language interface of CCICAI system not only increases the flexibility and adaptability of human-computer interaction, but also enhances the functions of the system.
