Design and Development of An Automated Conversational Chatbot Using Natural Language Processing and NLTK

Abstract

The Emergence of chatbots represents a pivotal advancement in Artificial Intelligence (AI) and Machine Learning (ML), impacting various sectors like Healthcare, Sports, Automation, and Education. Specifically, a recent application in education involves crafting chatbots capable of engaging with students, aiming to enhance the learning experience. This research paper targets Bachelor's programs, particularly in Computer Science Engineering and allied programs, by introducing a software bot named AI Sciences chatbot. Leveraging NLTK-Corpus library and Machine Learning models, this bot focuses on aiding the learning process of fundamental AI Science concepts within B.Sc Computer Science. The proposed system is to develop an online software bot that enables direct interaction between users and the bot, empowering students to pose queries without human intervention by using NLTK features and the ML model. The chatterbot is capable and proficient in comprehending and responding to inquiries based on a pre-defined dictionary, supplementing its knowledge by autonomously seeking information. The primary objective of this research is to implement a software bot within an online learning platform, facilitating seamless access for students to seek guidance, ask questions, and receive support 24/7, fostering a more efficient approach to their studies without constant human intervention.
