专家系统在果树中的应用及研究进展

专家系统是一种模拟人类专家解决领域问题的计算机系统,它主要分为知识库、综合数据库、推理机、解释器、接口等几部分。现今,国内果树专家系统的应用类型主要分为果树栽培生产专家系统和果树营养、病虫害诊断防治决策系统两类;在果树专家系统上的应用研究最多的计算机理论主要是：人工神经网络、模糊神经网络、多媒体技术、Web技术等;果树专家系统的开发手段主要是利用现成的农业专家系统平台直接进行二次开发,还有少数是直接利用程序语言进行原型系统开发。今后随着信息技术的不断发展,利用果树学的特点结合先进的计算机理论和技术,将开发出动态的、更具智能化的果树专家系统。     

An Expert Knowledge-acquisition Method on Line of Automatic Excluding Errors

Aimed at soving the problem existing in the knowledge-acquisition directing-operation expert systems, a new method is proposed to acquire knowledge of expert-operation, excluding errors existed in examples and reinforce the accuracy of examples,the goal of knowledge acquisition can be achieved, the method presented in this paper solves the problem of self-enhancement of expert knowledge on line efficiently.     

农业专家系统开发平台的研究现状及发展趋势

在中国，特殊的国情造成农业专家一般对计算机及其相关技术十分陌生，知识工程师对于农业知识知之更少，使得开发农业专家系统十分困难。专家系统开发平台的出现，使这个问题得到了缓解。农业专家无需掌握过多的编程知识就能建造性能良好的专家系统，而知识工程师只需研制开发平台，并根据领域使用要求，修改完善平台，无需掌握领域知识，两者相得益彰。在此，综述了近几十年国内外农业专家系统开发平台的研究及应用现状，提出了存在的问题，并介绍了农业专家系统开发平台的发展趋势，为农业专家系统开发平台在中国农业信息化中更好地服务提供参考依据。
