Knowledge-Based System Task Three

In this task, I have suggested some alternative for characters that were misidentify in task NN3. Table below shows some of the number characters that have been incorrectly identify as alphabet characters.


Rules have been written in such away that if any of the alphabets in the above table was entered in char3 or char4 (to simulate misidentification), the alphabet will be changed to the respective number. I have set the variable mark to become altered if the character has been change. It will then fire the rule altered_mark and the amended registration marks will be printed out from the console.
Finally all the codes for the three tasks were integrated together and add on to the file GET_MARK.KSL. An overview of how the program works in a forward chain are shown in the flowchart below
