Introduction to natural language processing: Building a basic chatbot

Abstract

Natural Language Processing (NLP) has become an increasingly important field in artificial intelligence, enabling machines to understand, interpret, and generate human language. This paper provides an introduction to NLP concepts and techniques, focusing on the development of a basic chatbot. We explore the fundamental principles of NLP, including tokenization, part-of-speech tagging, named entity recognition, and sentiment analysis. The paper then delves into the architecture and implementation of a simple rule-based chatbot, followed by an introduction to more advanced techniques using machine learning and deep learning approaches. We discuss the challenges and limitations of current chatbot technologies and provide insights into future research directions. The paper concludes with a practical demonstration of building a basic chatbot using Python, showcasing the application of NLP techniques in a real-world scenario.
