The Application Of CBR On Diagnosis Expert System Of Ginseng Disease And Insect Pests

Case Based Reasoning(CBR)has become one of the novel important reasoning ways because of its flexible approaches of reasoning,high efficient and intelligent reasoning mechanism and so on.It is a kind of reasoning method by calculating the similarity between the new cases and the existed cases in expert system. It only can be carried out by the minority ginseng experts that predicting ginseng disease and insect pests because it is many troubles. For example, there are too many kinds of insect pests and diseases during the ginsengs are growing,they usually burst out quickly, and the symptoms of them are similar and etc. It can not only be performed the predictive and treating work by ginseng farmers themselves, but also it can be drawn the new conclusions according to reasoning from unknown cases that reasoning technologies based on CBR are used. At the same times, it can improve the ability of the ginseng experts by using reasoning technologies base on CBR are used. At the same times, it can impove the ability of the ginseng experts by using reasoning technologies based on CBR when they solved actual problems. The important problems and algorithms which are used in the expert system of ginseng disease and insect pests based on CBR are mainly introdeuced in the thesis.
