Research Of Construction Of Expert System Based OOP

Expert system, simulating the reasoning of mankind through mechanism or electronic methods, is a field of artificial intelligence. Mature expert system has important economical and social values. OOP is a milestone in software industry, though it is only the changes of symbols, brings the revolution of the software construction.Based the deeply researches of the reasoning mechanism of expert system and the design pattern of OOP, I bring forward and explain the application of design pattern on expert system, the composition and resolving methods in the reasoning procedure, the algorism of removing loop rules, the related key algorism for reasoning, the knowledge base based on relation database, the construction of prototype medicine expert system, the model of how to construct an expert system based on Web.The main research of the article focused on the Construction of the expert system with design pattern of OOP, at the same time, some researches of reasoning mechanism.
