【摘要】 面向对象技术的成熟及其在知识库系统中的应用,赋予了知识库一些新的概念。我们就此进行了较为深入的研究,并对知识表达、推理等作了一些探讨,采用基于面向对象技术的原型-代理机制定义和设计了知识对象,实现了知识共享,并通过对象间的消息传递形成多个推理机场境,从而进行知识的推理。本课题初步实现了一个具有一定推理辅助决策能力的原型知识库系统。更多还原

【Abstract】 With the complete development of the object-oriented technology, the methodology of designing a knowledge base has been improved greatly. In this thesis,we bring forward the method of knowledge representation based on the mechanism of prototype - delegation.We have designed a knowledge base system that helps the managers to make right and effective decisions. In this system, knowledge can be shared and knowledge -reasoning can be carried out through the messaging between, the objects and the formation of inference engines’ environments.更多还原
