Based Expert System Web Elective System

Expert System is one of the most important and active fields in the artificial intellegence. With the realization that artificial intellegence comes into practical use from theoretical research, Expert System simulates all kinds of problems, which usually can be solved only by human experts, and becomes a computer intellegence progam system that has the equal problem-solving ability with the human experts.With the rapid development of Internet, designing and building Expert System through Internet is inevitable.Expert System (ES) in the Internet has higher share degree than conventional individual one. The Expert System design is based on the B/S of JSP/Server and provided with the multimedia interface on the Web Browser.The paper discusses the research situation home and abroad, its research purpose and meaning in detail and highly explores the expert knowledge expression and reasoning mechanism. It analyzes the developing trend of Expert System and comes up with one Expert System intergrated Web and reasoning technology. Meanwhile, according to the developing situatiion and tendency of Expert System home and abroad, teaching requirements and actual situation in our university education, the paper does the primary research on how to exploit course-choosing Expert System and its relative developing technology based on how the students effeciently choose the courses.The main researh features are listed as they follow:1.Based on the regular knowledge expression and the separation theory of knowledge base's design and reasoning mechanism, knowledge in the base can be easily corrected and expanded.2.Analysis on the knowledge reasoning mechanism, which is the key point of artificial intellegence course-choosing Expert System. The paper will discuss the artificail intellegence reasoning engine on WEB in the way of regular reasoning .3.Analysis on the realizing way and practicability according to the common WEB design language.
