Enhancement of Online Computerized Examination by Incorporating Artificial Intelligence to One Word Answer Questions Along with Multiple Choice Questions

Abstract

Today due to the increased number of various courses and increased number of appearing students, the process of examination has become more complex. Many hours of examiners and human efforts are required for effective evaluation of such examination. Computer is a powerful tool that can be used as a solution for such a complex problem. Many educational institutes, software industries, organizations, colleges, departments and universities have employed computerized on-line examinations which consisting of multiple choice questions that does not only perform the error free evaluation but also generates the fast result. It is a good solution than none but what about the evaluation of subjective type theoretical examination in which examiners have to decide and assign marks to the answers. To design such an intelligence system that automatically evaluates subjective type question answers require tremendous efforts including building of knowledge base for various subjects’ knowledge. Recently computer is widely used for online examination but in most of the cases only objective type multiple choice questions are involved. It is easier for a computer to evaluate objective type multiple choice questions but it is too much difficult for a computer to evaluate subjective type questions as similar as intelligent human efforts require. In this research paper here the effort is being made for the one word answer or fill in the blanks type subjective type questions with added intelligence at some extent. The examination process becomes interesting and interacting in which examinee is required to enter one word answer. The solution is obtained that will automatically evaluate, identify the answer text entered by the user and generating the correct text pattern suggestions which are phonetically nearer to the entered word only if it contains typographical mistakes. The solution can be implemented for on-line examination involving “Fill in the blanks” or “one word question’s answer”. This may be quite helpful for filling up the correct answers to the students who know the correct answers but not the correct spelling of the answer which encourage the students by suggestions, reliable effective evaluation, save time of teacher’s community and obtaining quick and error free result of examination.
