Objective of Research
This objective of the research work is the design and development of an expert system for the diagnosis of the diseases in the rice plant. Such an expert system is very essential for the farmers as experts are not always available with the farmers when the farmers required the advice from them and the diseases are one of the important factors for unproductivity of rice. When a farmer needs the advice of an expert, this expert system would provide the decision support to the farmer.
Artificial Intelligence and Expert System
Artificial Intelligence(AI) is a branch of computer science research.
It is intelligence of machines which aims at creating scientific goals and to understand intelligence by building computer programs that exhibits intelligent behavior.
AI has many branches such as expert systems, natural language, neural networks and robotics etc.
Expert System is a branch of AI program that achieves expert level competence in solving problems in task areas by bringing to bear a body of knowledge about specific tasks.
An expert system can explain their reasoning or suggested decisions, display intelligent behavior, draw conclusions from complex relationships.
Suitability and Feasibility of ES in Agriculture
Expert System can generate the information to the farmers by using its knowledge base and reasoning mechanism from human experts and other sources.
Expert System makes easier for a user to identify or describe symptoms with the information like image bases/textual bases as it is very difficult to describe in words.
The applications of expert system in agriculture are mainly found in the area of diseases diagnosis and pest controls. In agriculture, many domain specific expert systems are being used at different levels.
“An Expert System for diagnosis of diseases in Rice Plant,” is an application of expert system in agriculture. In this system, the expert system is developed with rule-based expert system, using ESTA (Expert System Shell for Text Animation).
