专家系统(ES,Expert System)是人工智能(AI,Artificial In-telligence)研究领域中最重要的分支,是计算机科学商品化的前沿.专家系统被认为是一种智能系统,它利用知识库和推理过程来解决那些需要有特殊专长的人类专家才能解决的复杂问题,并认为所运用的知识库和推理过程是该领域内最优秀专业人员的经验模型.它分4个逻辑部分:知识库、综合数据库、控制结构或推理机、人/机接口.
Expert system (ES) is the most important branch in the research field of Artificial Intelligence (AI) and the frontier of the commercialization of computer science.An expert system is considered as an intelligent system, which uses knowledge base and Reasoning process to solve the complex problem that can be solved by human experts who need special expertise and think the knowledge base and reasoning process used are the empirical models of the best professionals in the field.It is divided into four logical parts: Integrated database, control structure or inference engine, man / machine interface.
