Chatbots for Beginners: A Complete Guide to Build Chatbots - Machine Learning-Based Chatbots: Rule-Based Chatbots

This video tutorial covers the development of a rule-based chatbot using NLTK. It begins with package installation, followed by creating a corpus with Python. The tutorial then explains text preprocessing and helper function development. It also covers generating responses using term frequency-inverse document frequency (TF-IDF) and concludes with training and testing the chatbot.
