online courses(MOOKs platforms) to advance their knowledge. However, the sheer volume of available courses makes it difficult to identify the ones that truly align with a learner’s specific needs. Traditional course discovery methods are often generic and lack personalization, resulting in time-consuming searches and courses that may not match the user’s goals, prior experience, available time, or budget. +To address this challenge,we have derived a solution that simplifies the course selection process by providing personalized recommendations.
