Chatbots and conversational interfaces are reshaping how we interact with technology, but building one that truly understands human language requires a solid grasp of Natural Language Processing (NLP). This text-based course walks you through the essential concepts and practical steps to design, build, and deploy your own AI-powered chatbots. You will transition from understanding basic text processing to constructing functional conversational systems. By working through clear explanations and structured code examples, you will learn how to process text, manage conversation flow, and leverage modern AI models to create engaging user experiences. What you'll learn: Understand foundational NLP concepts, including tokenization, lemmatization, and part-of-speech tagging; Design conversational flows and manage user intent detection using pattern matching; Integrate modern language model APIs to enhance chatbot responsiveness and flexibility; Apply basic prompt engineering techniques to guide AI responses effectively; Implement retrieval-augmented generation (RAG) patterns to connect your chatbot to specific knowledge sources; Build and test a complete conversational agent from scratch. The course starts with core NLP definitions and text-processing fundamentals before moving into intent classification, dialog management, and modern API integrations. You will progress systematically from simple rule-based systems to dynamic, context-aware AI assistants.
