Abstract
In many expert systems classifier technique is successfully applied. Expert system means the system which makes decision based on provided knowledge by human expert and displays the result. Expert System contains knowledge provided by field expert in terms of rules. These rules are match with the system input and display the appropriate result of it. To minimize the effort of rule matching we apply classifier technique. By using decision tree classifier we reduce the size of the records for compare with previously design rules. After find the reduced set we apply rule matching on it and find out the exact rule match with user input
