Knowledge-based Native Xml Database System Application

The knowledgebase is expert system' s core. Each domain's knowledge has its own characteristic and exists overlapping and overlaps, therefore knowledge sharing and reusing is very essential. Many researchers have established the different knowledgebase system, because these system's knowledge has the greatly independence and closeness, therefore realize knowledge sharing and reusing is difficulty. This kind of situation caused the knowledgebase system which established with the massive energy has narrow application, and have little efficiency. Therefore the well design sharing and reusing system not only to reduce knowledgebase' s redundancy, guarantee knowledgebase' s succinct, but also enhance the knowledgebase' s performance and developming efficiency.Therefore this Dissertation based on the superiority technology of the XML, researched and realized one knowledgebase system based on Native the XML database, and applied this knowledgebase in the expert system of citrus. The key research points include: proposed production regular knowledge expression method based on the XML, this method has realized the knowledge unification and built the foundation for the knowledge interactive useing. Using one open source database system - - eXist pure XML database system to manage XML data, simultaneously has realized client knowledge demonstrates and the knowledge inquires based on XSP and the XSLT technology, as well as knowledge integration methods. This system solute the problem of knowledge independence and closeness, realized knowledge sharing, exchangeing and reusing, enhanced the development efficiency of knowledgebase enormously.
