摘要
由于农业生产的复杂性,玉米病虫草害的诊断对于农业技术人员经验的依赖很大。而玉米病虫草害诊断专家系统可以将这一复杂的工作变得更有成效。针对传统专家系统知识获取的"瓶颈"问题,在对玉米病虫草害症状框架描述的基础上,利用知识工程方法和技术,结合不确定性推理、匹配冲突消解策略和多媒体技术,实现了基于框架表示的玉米病虫草害诊治专家系统,用于模仿该领域专家思维,补充或代替农业专家指导玉米生产。本文主要阐述该系统的总体结构、知识表示、推理机制和系统实现与应用等方面问题。
The diagnosis and treatment of corn＇s diseases, pests and weeds depend on the experience of agricultural technicians greatly because of complexity of agricultural production. While the diagnosis and treatment of corn＇ s diseases, pests and weeds is able to make it complex task more effective, so it has been regarded to an expert stayed in rural areas. This paper in the view of the ＇ bottle neck＇ problem based on the frame description of symptom of corn＇s diseases, pests and weeds, this paper took advantage of knowledge project＇s method and technology, and combined uncertainty inference and dispelling strategy of matching conflict and technology of multimedia to realize the expert system of corn＇s diseases, pests and weeds which expressed on the basis of frame, and this system was used to imitate domain expert＇s thinking and supplement or substitute for agricultural experts to guide production. This paper emphatically expounded the questions which were the totality structure of system, knowledge express, inference mechanism, the realization and apply system and so on.
