摘要
采用“描述框架+规则组”的两级知识表示方法,“描述框架”定义问题域涉及的因素,“规则组”描述问题域内求解的问题.基于这种知识表示技术,设计实现了农业专家系统开发工具的知识管理子系统,并给出知识管理子系统中因素分类、知识检测、知识求精和知识发现等构件的实现方法.
Knowledge is described by ＂Depictive frame ＋ Rule group＂ in two stages, ＂Depictive frame＂ is used to reflect the factors concerning question field, ＂Rule group＂ reflects the son-question in question field. Based on this research, design and realize the knowledge management subsystem of developed tools of Agricultural Expert System in this paper. It presents the realizing methods of factor classifying, knowledge inspecting, knowledge refinement and knowledge discovery component in knowledge management subsystem.
