远程教育系统中知识表示的研究

Research on Knowledge Representation in Tele-Education

针对现有远程教育系统智能化低、知识表达能力差、结构化不清晰等方面的问题,引进了基于扩展标记语言XML(extesiblemarkuplanguage)的表示方法,并通过分析指出基于XML的表示方法在远程教育系统中的巨大优势;给出了一个通用的远程教育系统的体系结构,并用形式化的语言描述了该系统,最后将该形式化的语言转换为XML语言.

This paper discusses some problems existed in tele-education, such as low intelligence, weakness in the expression of knowledge expression, vagueness in configuration and so on, introduces into the ways of expression based on XML(extesible markup language), and points out the tremendous advantage of this means used in tele-education. Moreover, we present a universal system architecture of tele-education system and describe this system by adopting formalization language, and transform this formalization language into XML in the end.
