Exam Questions Classification Based on Bloom's Taxonomy: Approaches and Techniques

One of the most popular guidelines used to write and evaluate the exam questions is Bloom's Taxonomy (BT). Since the past recent years, many researchers have worked on the automation of exam question classification into BT. This paper gives a through overview of the standard approaches and techniques used in question classification (QC) into BT cognitive levels including the preprocessing, the dimensionality reduction, the classification and the evaluation stages. A comparison of some recent works related to the subject is also presented in this study.
