I. Introduction
One of the defining features of human progress in the twenty-first century is artificial intelligence (AI), which is also a crucial component of cutting-edge digitization [1]. A number of transformational applications have emerged as a result of the rapid breakthroughs in AI. The development of chatbots, which are intended to mimic human-to-human interactions, is one particularly noteworthy application. Chatbots have been very popular at educational institutions in recent years. They have shown to be useful resources for answering user questions and spreading information without the need for direct human engagement.
