Research on expert system for ginseng diseases and pests based on CBR

Abstract

In this paper, a kind of expert system for diagnosing of ginseng disease and insect pest-ES based on case-based reasoning (CBR) is introduced. Rule-based reasoning (RBR) is adopted in the expert system, and there are some problems in RBR usually, for example, system is difficult to defending, knowledge is troublesome to obtain, reasoning fragile and so on. The previously knowledge and experience of explaining similar question for proceeding reasoning may be used when the system based on CBR answers some questions, so that we can acquire the result of the present question. The core of CBR lies in abstraction of similarity and reasoning of history cases. This diagnosis thinking for something which is similar to actually expert diagnosis course, for another, we can full use previous experience of diagnosing and treating when diagnosing and treating ginseng disease and insect pests, which refrains from repetition work. There is well developing prospect on studying of similar agriculture expert system. © 2012 Springer-Verlag GmbH.
