AgPest is a Console User Interface based application. This expert system interacts with the user in textual mode. It gathers information from the user during runtime and keeps track of user response about environment, accordingly it
gives final decision. AgPest domain is agriculture and it is built for diagnosing rice and wheat pest disease management.
The development of AgPest involves following processes
Knowledge Acquisition
Knowledge Representation
Implementation in CLIPS 6.0
A. Decision procedure for Rice Pest-Management
As mentioned in earlier Knowledge Acquisition, knowledge Representation plays major role in performance of the overall expert system. These two stages are very important in development of any Expert System. In this paper ,for AgPest the domain knowledge information isgathered from Agroweb.
The rule base for Rice pest management contains various modules that contains different set conditions for testing diseases belongs to that module. These conditions are nothing but symptoms of a particular disease. During the execution/runtime expert system checks these conditions based on user responses to the set of fired questions. This evaluation of conditions is done at runtime, for this purpose AgPest keeps track of user responses.
