Expert System Of Cow Based On WEB

In this paper, we present the construction of Web-based Cow Expert System. After analyzing foreign and domestic agricultural expert systems, we put forward the scheme of the system, which uses the structure of Browser/Web Server/Database. Due to Active Server Pages and XML, the Cow Expert System can be accessible through Internet/Intranet, and has good backward compatibility, meanwhile, needs less effort to update the system. Following technologies are introduced: knowledge representation method based on fuzzy production rules; forward and backward chaining; approximate reasoning based on CF model; departed knowledge base and inference engine; ASP/ADO, XML technology.These technologies ensure the extensibility of system and lower the complexity of system maintenance.
