基于产生式规则的形式推理系统研究与实现
 
摘要：目前专家系统在各个领域中的使用非常广泛，而要建立1个好的专家系统除了需要有良好的领域知识以外，还需要对专家系统有着深入的了解，例如需要深入研究适合该领域的知识表示形式、知识存储方式、推理方式等等。本文主要介绍了动物识别专家系统的设计与实现过程，包括研究专家系统的理论基础、总体架构、知识库的组织形势和存储结构、推理机系统等等。并采用面向对象与面向过程相结合的方法设计实现了1个动物识别专家系统。第1章是绪论，介绍了专家系统研究的1般特点，回顾了国内外专家系统的发展概况和研究现状，并对本文做出了概述。第2章研究了各种知识表示方式。第3章主要介绍了推理的控制策略和推理策略。第4章对可以改进的地方进行了探讨。第5章对总体结构进行了分析和设计，给出了系统类结构、类定义和系统各模块的主要功能。第6章对本文工作进行了总结。

Studying and Implementation of Inference System on Production Rule
 
Abstract: Today expert system was widely applied in many fields. In order to build a well ES, besides well fields knowledge, understand in-depth was needed, for example, knowledge representation method、knowledge save method and reasoning model etc. This paper mainly introduced designing and realization of animal‘s recognizing system, that includes theory basis、integer construction of expert system; organization and save method of knowledge base、reasoning machine system etc. And designed and implemented a animal’s recognizing expert system by combined object orient analysis and process orient analysis. The chapters 1 introduced function of expert system, and reviewed its general development and status in quo overseas and internal, and introduce the article briefly. The chapter 2 studied mainly knowledge representation methods. The chapters 3 introduce the reasoning machine system. The chapters 4 discussed its shortpoints and improve it. The chapter 5 analyzed and designed the system collectivity structure, and given system class configuration、system class definition、system structure figure and functions of every module. The chapter 6 summed up this paper, and discussed some aspects that can be improved. （转载自http://zw.ＮＳＥaＣ.com科教作文网）
