WEB-based Expert System Of Course

With the network technology and the rapid development of informationtechnology and the continuous deepening of reform of educational system, electivecourses in secondary vocational schools to carry out daily teaching occupy anincreasingly important position. Students learn through elective courses to expandmore knowledge, only when the rich knowledge, the students future employmentopportunities will be more broad. But not only the traditional manual elective spend alot of manpower and financial resources, but also the efficiency of course quite low.In addition, because part of the student’s own learning situation is not veryunderstanding, resulting in when students choose elective courses of study after aperiod of time only to find themselves on the selected course or not interested enoughto learn their knowledge reserve the selected program, the resulting elective studentslearning ineffective, thus wasting valuable resources and student learning electivetime.According to the above situation, this article how to guide students in secondaryvocational school enrollment issues effectively as the background, through thedevelopment of a student elective can improve the efficiency of elective system,thereby reducing the blind student elective course caused a waste of resources.The system uses a WEB-based expert system (Expert System, ES). WEB-basedexpert system than the traditional expert system has a higher degree of flexibility andsharing. Expert in the design of the system using Three-Layered ServicesApplication mode architecture provides Web browser-based multimedia userinterface.The main research contents are as follows:1、Preclude the use of a rule-based knowledge representation, inference engineand knowledge base using the principle of separation of design makes easy to expandthe knowledge base of knowledge and modify.2、Elective expert system knowledge reasoning is the core part of this paper, therule-based reasoning method, select the appropriate method of reasoning, analysis anddesign of WEB-based intelligent reasoning engine. 3、Combined with expert systems and network technology features, the systemmainly uses.NET-B/S three-tier architecture to plan the structure of the entire system.
