A Machine-Learning Based Approach to Validating Learning Materials

In this paper, we propose a Machine Learning-based approach to validate suggested learning materials. Learning material validation is an essential part of the learning process, ensuring that learners have access to relevant and accurate information. However, the process of manual validation can be time-consuming and may not be scalable. Traditional learning contents are often only updated or changed in the yearly course revisions. This can be presented with some challenges, especially to courses on emerging subjects and catering to diversified learners, which includes the ability to provide adaptive and updated learning contents to the learners, and the opportunity to continually incorporate feedback. We present a solution and framework that utilizes machine learning algorithms to validate learning materials in an open learning content creation platform. Our approach involves pre-processing the data using Natural Language Processing techniques, creating vectors using TF-IDF and training a Machine Learning model to classify the subject of the learning material. We then calculate the similarity with existing materials for the given course to make sure there is not an existing mate-rial with same content and the new material will add new value. Using an augmented TF-IDF score, we check if the suggested learning materials satisfies the key phrases for the course. We evaluate our approach by comparing the Machine-Learning based approach to manual validation. Not only does the machine-learning based approach reduce the time and effort needed for validation, but it also achieves high accuracy in detecting duplicates and similarity matches.
