作为“电业职工智能培训系统关键技术研究”系列文章中的第二篇 ,主要研究智能培训的知识表示问题。智能培训系统中的知识 ,包括系统讲授的领域知识和在教学过程中积累的经验知识。详细介绍了领域知识和经验知识的表示 ,以及如何建立通用的知识库 ,以便使没有编程经验的领域专家也能在此基础上建立自己的知识库 As the second part of the series of articles on “Research on Key Technology of Intelligent Training System for Electric Workers,” it mainly studies the knowledge representation of intelligent training. Knowledge in the intelligent training system includes domain knowledge taught by the system and empirical knowledge gained during the teaching process. Described in detail the domain knowledge and experience knowledge representation, and how to establish a common knowledge base, so that there is no programming experience in the field of experts can also build on their own knowledge base
