摘要
提出了一个基于远程虚拟实验的实时智能指导系统(intelligent tutoring system,ITS),该系统用来模拟教师的决策,在虚拟实验过程中给学生提供实时指导.该系统扩展了传统的ITS四库体系结构,并运用面向对象的技术,设计和实现了多级知识库结构和混合模式的多级目标推理机.详述了该实时智能指导系统的知识库结构、知识表示和推理技术,并通过实例验证了该系统的可行性和有效性.
A real-time intelligent tutoring system （ITS） for distance virtual experiment （DVE） was presented to simulate teachers＇ decisions, providing real-time instructions to help students in the process of a virtual experiment. The typical four-module architecture structure of the old ITS was extended in this system, and the object-oriented technology was used to design and implement the multilevel knowledge base structure and the multilevel target, mix mode reasoning machine. The structure of knowledge base, knowledge representation and reasoning machine were technically considered, and a sample was built to show the feasibility and efficiency of this approach.
